The Factor Structure of Mutual Fund Flows ABSTRACT Common flow factors explain significant fractions of annual and quarterly flows to US mutual funds. Common flow factors are highly autocorrelated and are correlated with financial market yields, macroeconomic variables, investor confidence and market volatility at various leads and lags. The systematic components of flows differ across funds according to funds’ “flow betas.” Equity fund flow betas depend on past performance and fund characteristics, such as size, age and expense ratios. High flow beta funds offer significantly lower subsequent returns. Decomposing mutual fund flows into common and idiosyncratic components also generates new insights about the “flow-performance” relation in equity funds first observed by Ippolito (1992) and the “smart money” effect in fund flows first documented by Gruber (1996).
1. Introduction
The determinants of the flows of money into mutual funds are important to understand for
macroeconomic, microeconomic, financial economic and practical reasons. From a macroeconomic
perspective mutual funds capture a substantial fraction of consumer savings, affect the allocation of
that capital, and are likely to be a key factor in retirement outcomes for many households. Money
market funds are key lenders in the repurchase markets, important in funding fixed-income broker-
dealer operations and for implementing Federal Reserve policy. From a microeconomic perspective,
fund flows are a window into individuals' investment decisions. Financial economists study mutual
fund flows for insights about fund managers' incentives, investor behavior and the efficiency of
financial markets. The flows of moneys in and out of mutual funds may affect prices in financial
markets. Finally, mutual fund managers care deeply about fund flows, as their compensation is
linked to flows through the levels of assets under management.
Like asset returns and liquidity, the flows of money into mutual funds have common
components and fund-specific or idiosyncratic components.1 This paper explores mutual fund flows
from this perspective. Previous studies have extracted common factors from mutual fund returns (e.g.
Elton, Gruber and Blake (1999) and Brown, Goetzmann and Grinblatt (2004)) but less is known about
the common factors in mutual fund flows. Goetzmann, Massa and Rouwenhorst (2008) study factors
in a small sample of daily fund flows during 18 months of 1998-99. We focus on quarterly and annual
flows for a large sample of stock, bond and money market funds during 1981-2009. Decomposing the
flows into common and idiosyncratic components generates a number of new insights.
The systematic components of fund flows represent significant fractions of the
variation in individual fund flows over time. In a statistical factor analysis the first common factor
captures about 11% of the variance of percentage flows for US equity funds during 1981-2009, and the
first six factors capture more than 43%. For bond funds the figures are in a similar range, and slightly
lower for money market funds.
1 Common factors in stock returns have been explored since King (1966) and common factors in liquidity since

The common factor in percentage equity fund flows are related to contemporaneous
values of macroeconomic and financial market variables such as aggregate stock market returns,
consumer confidence, the value of the US dollar and the growth rate of industrial production and
stock market volatility. A time-series regression of the first equity factor on a collection of a dozen
contemporaneously measured macroeconomic and financial variables produces an adjusted R-
squared of 39%. For bond funds we get 37% and for money funds, 30%. While the finance literature
finds it difficult to explain much of the variance in financial asset prices using macroeconomic
variables, the common factors in mutual fund flows respond strongly to macroeconomic conditions.2
We examine the predictability of the common factors in mutual fund flows. The flow factors display
significant and complex autocorrelation structure with substantial persistence, and some relation to
lagged macroeconomic and financial market variables. In the sample, we find adjusted R-squares
exceeding 60% in regressions predicting flow factors for bond funds, using lagged flows and
economic variables, and the R-squares are about 25% for equity funds and 13% for money market
funds. Lagged flows also bear a predictive relation to future values of variables that represent
economic conditions, suggesting that in the aggregate, fund investors do not simply chase the past
(performance), but look to expected future economic conditions.
Common flow factors are closely related to sector-wide flows. Value-weighted and
equal-weighted flows for each fund sector (stock, bond and money market) have correlations with the
first common statistical factors in that sector of at least 76% annually and 55% quarterly. Thus, the
first common factor may be roughly interpreted as the sector-wide flow.
There is substantial variation across individual mutual funds in the sensitivity of their
flows to the common flow factors. The “flow betas” that describe this sensitivity may be roughly
interpreted as the marginal “market share” of new sector flows that a fund receives. We find that
flow betas depend on characteristics of a fund such as its size, age, expense ratio and recent return
Chordia, Roll and Subrahmanyam (2000). 2 Other studies have observed that aggregate mutual fund flows are related to economic conditions. See for example, Warther (1995) and Chalmers, Kaul and Phillips (2007).

performance. Equity fund flow betas are also asymmetric. High-performing funds have lower flow
betas when the aggregate flow is negative. Thus, when flows are strong, high performing funds
increase their market share and when there are negative sector flows, their market share loss is
smaller than funds with weaker recent return performance. High-performing funds’ common factor
flows bear an option-like relation to the aggregate flows.
We find that equity funds with higher flow betas on large sector outflows offer lower
subsequent performance. Such funds have to sell assets when other funds in the sector are selling.
The difference between the average returns of the high and low quintile of equity funds, sorted
quarterly on the lagged flow beta on sector outflows, is 23-30 basis points per month and significant
after adjustment for standard return factors. This effect adds a new dimension to the “fire sales”
phenomenon studied by Coval and Stafford (2007), who examined the individual stocks held by funds
experiencing large negative total flows.
Studying the common and idiosyncratic components of funds’ flows refines our
understanding of other stylized facts in the mutual fund literature. One is the “flow-performance”
relation documented by Ippolitto (1992), Sirri and Tufano (1998) and Chevalier and Ellison (1997).
Here we find that common and idiosyncratic flows behave differently in flow-performance
regressions, and these differences are related to changes in the overall relation over time. A second
application is the "smart money" effect of Gruber (1996), who finds that new money flows into US
equity mutual funds earn higher returns than existing shareholders. We find that this effect, to the
extent that it exists in our data, is concentrated in the common factor component of fund flows.
The rest of the paper is organized as follows. Section 2 describes our data and
empirical methods. Section 3 presents the analysis of fund flows and their common factors. In Section
4 we examine the relation between flow betas and fund performance and summarize the implications
of common and idiosyncratic flows for the flow-performance relation and smart money effects.
Section 5 concludes and offers suggestions for future research.

2. Data and Methods
We study data for 1980-2009 from Morningstar on US Equity funds, bond funds and taxable money
market funds. We use Morningstar's fund classifications. The Equity funds exclude balanced funds,
asset allocation funds, closed-end funds and index funds identified by Morningstar from the funds'
prospectuses. The bond funds exclude closed-end and municipal bond funds, and the money market
funds exclude tax-exempt funds.
We subject the funds to a number of screens. To minimize incubation and the
associated back-fill bias (e.g. Evans, 2010) we exclude funds that had less than $5 million in total net
assets at the end of the previous year, and we exclude the first year for each new fund. We also
exclude funds for the year in which they record an extreme flow observation (less than -100% or
greater than 500%). This leaves us with a total of 28,078 fund years, where the number of equity funds
is 183 in 1981, rising to 2,046 in 2009. For bond funds and money market funds, the number of fund
years is 15,801 and 9,774, respectively (data start from 1992). Table A.2 in the Appendix provides
summary statistics for the mutual fund sample.
The percentage flows of new money are defined in the usual way as:
Fit = [TNAit - TNAit-1(1+rit)]/TNAit-1, (1)
where TNAit represents the total net assets of fund i at time t and rit is the reported return for the
period from t-1 to t. We use annual and quarterly flows.3
Figure 1 presents time-series plots of (value and equally-weighted) aggregate flows for
the three fund sectors. Broadly speaking, the series appear stationary, but display some persistent
multi-year swings (we examine the autocorrelations below). For example, money market fund flows
3 When mutual funds merge, the calculation in (1) is adjusted for the effects of the merger to avoid the appearance of spurious flow to the acquirer. Given a merger the selling fund dies and we reduce the buying fund’s reported, newly-combined TNAt by TNAs,t-1(1+rst)f, where s indicates the selling fund, rst is the selling fund’s return for the period during which the merger took place and f is the fraction of the period prior to the recorded merger date.

recover from a negative position around 2005 and increase until around 2008, declining through the
end of the sample. Bond fund flows turn negative in the 1990s and the year 2000, then rise
dramatically from 2005 to the end of the sample on an equally-weighted basis, but the value-weighted
(and total dollar) flows turn briefly negative during 2003-2004 and 2008-2009. Equity fund flows
appear to trend downward since the 1990s, but remain positive on an equally-weighted basis. The
total dollar flows to equity funds turn negative during 2002-2003 and from mid-2007 to 2008. These
figures suggest that there have been periods where flows move across market sectors, such as the late
1990s, and also periods of inflows and outflows for the whole industry, such as in 2003.
2.1 Factor Extraction Methods
We decompose the fund flows into systematic and fund-specific or idiosyncratic
components using a factor model:
F = 1Ta' + YB + u, E(u)=0, E(u'Y)=0, (2)
where F is a T x N matrix of flows for T periods on N funds, Y is a T x K matrix of common flow
factors, B is a K x N matrix of factor loadings, a is an N-vector of intercepts, 1T is a T-vector of ones
and u is the idiosyncratic residual. The residuals are assumed to be idiosyncratic in the sense that
E(uu’/N) has bounded eigenvalues as N goes to infinity, while E(FF’/N) has K unbounded
eigenvalues. Connor and Korajczyk (1986) provide conditions under which the first K eigenvectors of
(FF'/N) converge to the common factors, Y, to within a K x K rotation, as N goes to infinity. We use
these scaled eigenvectors as the common factors in mutual fund flows.
The Connor and Korajczyk approach to factor extraction is attractive here, compared
with traditional factor analyses or principal components based on the N x N covariance matrix. There
are many mutual funds with short time series, so N is large compared to T. The T x T matrix (FF'/N)
is therefore more tractable, and it makes more sense to rely on N-asymptotics. Leaving out the funds
6
with missing data could create sample selection biases. Fortunately, Connor and Korajczyk (1988)
show that we can use their approach with missing data, by simply averaging over the available funds
for each date-pair corresponding to an element of the FF' matrix. The result is K factor time series of
length T, with no missing observations.
We extract fund flow factors separately for equity, bond and money market funds, but
we are also interested in common factors across the market sectors. To this end we use the approach
advocated by Goyal, et al (2008). This approach starts with the common factors extracted separately
for each sector. Let xis be the i-th orthonormal eigenvector from sector s. The eigenprojection matrix
ΣiΣs (xis xis’) is formed and its principal components are extracted. This allows for common factors
that may be sector-specific or shared across sectors.
The factor extraction assumes that the factor loading matrices are fixed over time. This
may not be true, and we find strong evidence for time-varying "flow betas." To avoid internal
inconsistency we estimate the common factors using a conventional rolling estimation scheme. Here
we take rolling overlapping subsamples with T=12 years (or T=48 quarters), extract the eigenvectors
and associate the last value of the common factor realization in each subsample with the last period in
the subsample. We roll the whole procedure forward to obtain a time series of common factors that
are not forward looking and admit that the loadings may be time varying.4
2.2 Factor Extraction Results
We examine Scree plots (Cattell, 1966) of the eigenvalues. Here we look for a number K
such that the next smaller eigenvalue drops off dramatically. A number of formal tests are available
(see Connor and Korajczyk (1993) and Brown, 1989). In the context of an approximate factor structure
we should see that the pervasive eigenvectors have exploding eigenvalues as N gets large, so the
number of eigenvalues below any finite cutoff point is an N-consistent estimator (e.g., Bai and Ng
4 Fund flows might represent fertile grounds for future work using dynamic factor models. However, as the results of our two approaches are similar, we resist putting the additional structure on the data.

(2002), Onatski (2006)). Ahn and Horenstein (2009) propose a test based on the ratios of adjacent
ordered eigenvalues which exploits this feature of an approximate factor structure.
The ratios of the adjacent ordered eigenvalues are plotted in Figure 2 for the equity,
bond and money market sectors. In the left-hand panels the full 1981-2009 sample is used for equity
funds (1992-2009 for bond and money funds). In the right-hand panels we present the averages for
the rolling subsamples.5 We evaluate these figures informally. As is common in applications of factor
analysis on stock returns, the first factor appears to dominate in most cases, and we see a big spike at
K=1. But there are peaks that suggest that 6-8 factors may be important for equity fund flows. Rolling
estimation suggests a smaller number, typically three equity flow factors. The ratios for bond funds in
Panel B suggest four dominant factors in annual data, and five in quarterly data, but maybe only one
in the rolling estimation. For money market funds the graphs in Panel C suggest one, or at most three
common factors.
It makes sense that rolling estimation indicates a smaller number of common factors. It
is well-known that a factor model for returns with time-varying betas can generate an unconditional
model with fixed betas and more factors (e.g. Cochrane (1996), Jagannathan and Wang, 1996). A
similar phenomenon likely occurs for fund flows.
2.3 Factors Common across Sectors
The analysis combining the sectors is summarized in Figure 3. Here we combine the
six common equity flow factors with three bond and two money fund flow factors. The approach thus
produces a maximum of eleven nonzero eigenvalues, and the smallest estimated eigenvalue is often
very close to zero. This generates a spike in the last eigenvalue ratio, which we interpret as spurious.
Figure 3 shows the first ten raw eigenvalues, which are more informative for this analysis. Given that
the eigenprojection matrix ΣiΣs (xis xis’) is constructed with unit weights on the eigenvectors its
eigenvalues have a special interpretation. The number of eigenvalues equal to 1.0 is the number of
5 We also examined the individual rolling estimation results but did not find any notable trends.

sector-specific common factors. If two sectors share a common factor it will be “double counted” and
its eigenvalue is 2.0. Similarly, a factor common across all three sectors produces an eigenvalue equal
to 3.0.
Of course, estimation error affects these calculations. Measurement error reduces the
eigenvalues, on the assumption that the true and measured eigenvectors are both orthonormalized.
Under these assumptions imperfect correlation across sectors means that a factor common across two
sectors has an eigenvalue of (1+ρ)<2, where ρ is the correlation. Thus, instead of the idealized step
function we expect a smoothed graph in practice and that is what we find in figure 3. Figure 3
suggests that there is at least one factor that is common across all three sectors, and one or two more
with two sectors in common.
3. Empirical Results for Flow Factors
In this section we first deal with seasonality in quarterly fund flows and illustrate the common flow
factors. We then explore the relation of the common flow factors to contemporaneous macroeconomic
and financial variables. Third, we explore predictive relations involving the common flow factors.
Fourth, we examine the determinants of funds’ flow betas.
3.1 Seasonality
Quarterly fund flow data may have seasonal patterns. Table 1 summarizes regressions
of individual fund flows on four dummy variables for the quarter of the year. The seasonal patterns
are not strong, but often statistically significant. The mean adjusted R-squares of the regressions are
between 6% and 14% for the three fund sectors; highest in the money fund sector. The distributions
of the R-squares across funds are slightly skewed to the right, with the medians between 2% and 7%.
The extreme 5% right-tail values are greater than 50%. The coefficients in Panel B show that equity
flows are larger in the first half of the year, while money fund flows are negative in the second quarter
and largest in the fourth quarter on average. We use a seasonally-adjusted quarterly flow series in all
9
of our analyses, including the factor extraction described above. For each fund the quarterly
seasonally-adjusted flow is the sample mean flow for that fund plus the residuals of the dummy
variable regression for that fund.
3.2 Time Series Plots and Summary Statistics
Figure 4 shows the annual time-series of the first common factors for each sector and
the first overall common factor. These may be compared to the aggregate flows depicted in Figure 1.
Since the factor analysis only identifies common factors to within a rotation, we scale the first
common factors so that the beta of a value-weighted portfolio of funds on the factor is equal to 1.0.
The first common factors display a great deal of similarity to the aggregate sector flows, picking up
most of the peaks and troughs, although sometimes with different amplitudes. This foreshadows
results below that suggest the first factors well represent the sector aggregates.
Panel C of Table 1 presents the simple correlations among the first factors in each sector and
the first overall common factor. The overall factor is highly correlated with the first factor in equity
fund flows (72%-73%) and has moderate positive correlation with money fund flows (34-43%) in
quarterly data but bears little correlation to bond fund flows.
3.3 The Explanatory Power of Common Factors for Individual Funds’ Flows
Table 2 summarizes the adjusted R-squares, regressing the flows of individual funds on
the common factors over time. Each fund's regression uses all of the flow data for that fund, provided
at least K+3 observations are available when K factors are in the regression. The means of the
adjusted R-squares taken across all of the funds are shown for various values of K, as well as other
statistics of the cross-sectional distributions, including the values at various fractiles of the
distributions.
Panel A of Table 2 presents the results for equity funds. The average R-squares have an
interpretation similar to the communalities in a traditional factor analysis. On average the first
10
common factor explains about 11% of the variance of annual flows and 8% of the seasonally-adjusted
quarterly flows. With six factors the R-squares increase to about 43% annually and 30% quarterly.
Given that the mean R-squared of the seasonal-adjustment regression is about 7%, the overall R-
squares at the quarterly and annual frequencies are similar. Thus, common factors explain a
substantial fraction of equity mutual fund flows. Panel B presents the results for bond funds and
panel C, for money market funds. These regressions show similar R-squares for the bond funds and
slightly smaller for the money market funds, where one factor delivers an average R-squared of 8%-
10% and six factors deliver 18%-44%.
There is substantial dispersion across funds in the R-squares. For example, the cross-
sectional standard deviation of the R-squares on the first factor is at least two or three times the mean
value in each sector. These differences in R-squares reflect the significant heterogeneity in “flow
betas,” or the loadings of the funds’ flows on the common flow factors.
Panel D of Table 2 summarizes the R-squares for the pooled sample of funds, regressed
on the overall common factors extracted using the Goyal et al (2008) technique. The results for
quarterly and annual flows are similar. Using one factor the average R-squared is 9.9% and with six
factors it is 32.4%. The interquartile range with six factors covers 39.8%-60.3%, and more than 5% of
the funds have an adjusted R-squared of 90% or greater with six factors in annual data. Thus, the
common factors in flows are important and the relative importance of common factors differs
substantially across funds.
3.4 Economic Variables, Financial Market Variables and Flow Factors
In this section we examine the relation between fund flow factors and
contemporaneous values of macroeconomic and financial market variables. There may be common
factors in mutual fund flows because many investors are affected by the state of the macroeconomy
and business conditions in similar ways, or because investors respond to financial market information
in similar ways. We examine measures of the macroeconomy, financial markets and investor
11
sentiment. The macroeconomic variables include the growth of personal disposable income,
industrial production, inflation and an index of the relative value of the US dollar against major
trading partners. The financial market variables include stock market volatility, the excess returns of
stocks over bonds, a short-term Treasury bill rate, yield spreads of AAA corporate bonds over
Treasuries, of BAA over AAA bonds, and the difference between the value-weighted dividend yield
and the yield on a 10-year US Treasury Bond. Details about these data are provided in the Appendix,
tables A.1 and A.3.
Goetzmann et al (2008) extract factors from daily flow data over an 18-month sample,
1998-1999 and argue that "behavioral" factors reflecting investor sentiment are important in mutual
fund flows. To investigate this directly we include the index of investor sentiment from Baker and
Wurgler (2006) as an explanatory variable. We also include the change in the Michigan consumer
confidence index.
Table 3 presents simple correlations of the annual first common flow factors from each
sector, and the first overall factor, on contemporaneous values of economic and financial variables.
We find that the first factor in percentage equity fund flows is positively related to the change in the
Michigan sentiment index, the value of the US dollar and industrial production growth, and
negatively related to stock market volatility. The first bond flow factor is positively related to the slope
of the term structure and stock market volatility, but negatively correlated with the level of the short-
term Treasury rate. The correlations to market volatility and sentiment make sense as a “flight to
quality” phenomenon. When the stock market is volatile and sentiment is pessimistic investors
reduce equity fund purchases and increase bond fund purchases. Bonds earn higher average returns
when the slope of the term structure is steep, so the correlation with term spreads is consistent with
bond fund flows systematically chasing the higher expected returns.
The first money market flow factor is positively related to the value of the dollar, the
credit spread and the yield on BAA corporate bonds, and negatively related to consumer confidence,
inflation, and industrial production growth. These correlations generally make intuitive sense.
12
Investor flows into money market funds are high when consumer sentiment is pessimistic, real output
is down and interest rates are high. The opposite signs of the correlations for money market and
equity fund flows reflect the fact that flows cross between stock, bond and money markets. At the
same time, the value of the US dollar is positively related to stock and money fund flows, indicating
common factors that work in the same direction across the sectors.
Common factors spanning the sectors should be captured in the overall common flow
factors. Column D of Table 3 presents the correlations of the first overall common factor and finds
strong correlations with the macroeconomic and financial market variables. Industrial output, the
value of the US dollar, financial market yields and stock market volatility all present significant and
often strong correlations.
Table 4 presents the results of multiple regressions for the common factors on
contemporaneous values of the explanatory variables. Panels A-C present results for the equity, bond
and money market flow factors and panel D presents regressions for the overall common factors.
Four regression models are presented in each case: one isolates the macroeconomic variables and a
second brings in the measures of consumer confidence and sentiment. A third isolates the financial
market variables and a fourth model combines the variables.
Significant fractions of the variance in the sector flow factors are related to the
macroeconomic variables. Previous studies have a hard time associating much of the variance in stock
returns to macroeconomic variables (e.g., Roll 1988). In contrast, Panel A of Table 4 shows that the
macro variables produce an adjusted R-square of 22% for the first equity fund flow factor in annual
data. The financial market variables do not dominate the macro variables in the annual regressions,
and both sets of variables contribute significantly to the explained variance of the combined model.
In quarterly flows the macroeconomic variables deliver smaller R-squares, which could be related to
the larger measurement errors in quarterly macro data, and the financial market variables provide
most of the explanatory power at the quarterly frequency. The combined regression models produce
adjusted R-squares near 40% for the first equity factor at either frequency. The R-squares are slightly
13
higher for the third factor (not tabulated), which seems to be more strongly related to the financial
market variables. The R-squares are generally smaller for higher ordered factors.
The explanatory variables are correlated (their correlations are displayed in the
Appendix Table A.3), so the t-ratios of the multiple regressions help discover which variables survive
on a partial correlation basis. Stock market volatility and the credit spread emerge as important
variables for annual equity fund flows. The BW sentiment index, stock market returns, inflation and
the dividend yield spread also survive in quarterly data, but the signs on sentiment and the dividend
yield spread are counterintuitive in the quarterly data.
The multiple regressions for the bond fund flows are summarized in Panel B of Table 4.
Because of the shorter sample period (1991-2009) we present multiple regressions for the quarterly
flows only, and present results for the first two factors. The adjusted R-squares of the combined
models exceed 37% for the first factor and 64% for the second factor. The first quarterly bond fund
flow factor bears little relation to the macro variables or sentiment with the exception of inflation and
the exchange rate, and appears to be largely driven by interest rate spreads. The second factor in
contrast is significantly related to the BW investor sentiment index (with a negative sign) as well as
financial market variables including stock market volatility and the dividend yield spread.
Panel C of Table 4 presents the regressions for the first two money market fund sector
flow factors, again using quarterly data. The full models have the smallest R-squares of the three
sectors, but are still significant at almost 30% for the first factor. The first factor is mainly driven by
financial market variables, with little relation to the macro variables. The first factor is positively
related to stock market volatility and negatively-related to sentiment, contemporaneous stock market
returns and the dividend yield spread. The second factor, however, is positively related to industrial
production growth. Panel D of Table 4 examines regressions for the overall common factors that
combine the three fund sectors. Again only quarterly data are used. Both the macro and financial
market variables capture significant fractions of the flow variance, but the financial variables
dominate. The financial market yields, inflation, exchange rates and the BW sentiment index (again,
14
with a negative sign) show the strongest relations. The combined models’ R-squares exceed 65% for
the firstfactor, but only reach 18% for the second factor. Thus, the common factors extracted from
mutual fund flows are strongly related to economic conditions.
3.5 Predicting Flow Factors
Several previous studies examine the predictability of mutual fund flows, but do not
break the flows down into their systematic and idiosyncratic parts. Table 5 presents the first eight
autocorrelations of the first common flow factors; Panel A with annual data and Panel B with
quarterly data. To ensure that the factor extraction itself induces no look-ahead bias we use factors
extracted with the rolling method in all of the subsequent analysis in Section 3. The table shows that
the common factors have interesting autocorrelation structure. In annual data, the first order
autocorrelations of the first factor are 0.73 for equity fund flows, 0.43 for bond funds and almost 0.80
for the overall common factor. The first money fund flow factors show much smaller autocorrelation.
Higher ordered factors also have high autocorrelations. There seems to be a lot of persistence in
percentage flow factors. In some cases an AR(1) with a positive coefficient might be a good
approximation, but in others the autocorrelation structure appears more complex, with sign switches
over the periodogram. The quarterly data presents even larger autocorrelations in many cases. This
rich autocorrelation structure indicates significant predictability based on lagged flows.
While the autocorrelations of the flow factors are substantial, the largest value in the
table is less than 0.92. This suggests that the lagged flows may be used as predictors in regressions,
reported below, without undue concerns about spurious regression bias. Ferson, Sarkissian and
Simin (2003) find that these issues arise mainly with autocorrelations larger than 0.95.
Table 6 presents regressions that attempt to predict the first common flow factors using
lagged predictor variables. The predictor variables include the own-lagged flow factors and the
lagged values of all the variables that were measured contemporaneously in Table 4, and we
summarize the results with time-series regressions over the full sample period. Four regressions
15
models are presented, similar to Table 4.
Panel A of Table 6 presents the regressions for equity fund flows, both annual and
quarterly data. The results for the annual regressions are stronger. The regressions suggest
predictability in the flows related to lagged macro variables (mainly, the exchange rate and disposable
income growth) and financial market variables (mainly, market volatility and interest rates). There is
little predictive relation using the lagged investor sentiment indexes. The adjusted R-squares of the
combined models are about 25% both in the annual and the quarterly data. Thus, the common
components of equity mutual fund flows are characterized by substantial predictability over time,
much of it attributed to the relationships with macro and financial conditions.
Ferson and Warther (1996) find that the first differences of aggregate monthly flows
into equity mutual funds may be predicted during 1968-1990 using lagged short term interest rates
and dividend yields, but they do not include macro variables or other lagged flows in the models. We
find significant t-statistics for the annual equity fund flow on the lagged market volatility index and
the lagged term slope, but not on the lagged dividend yield, and the adjusted R-squares of the model
isolating financial market variables is 26% in annual data. In quarterly data only market returns
appear as significant predictors in the model isolating financial market variables, and the adjusted R-
squared of this model is only 11%. However, none of the financial market variables, excepting the
exchange rate, remain significant in the combined model that includes the lagged flows in the
quarterly data.
Panel B presents the predictability regressions for bond funds, using quarterly data
beginning in 1992. Like in the equity funds in quarterly data, lagged flows are main predictors. The
combined model does feature significant t-ratios on the consumer sentiment and the credit spread.
The combined model’s adjusted R-squared is 64%.
Panel C presents the regressions for quarterly money fund flows, where the combined
model produces a smaller adjusted R-square of 13%. The market return survives with a t-ratio of -1.7.
Unlike the case of equity fund flows and bond fund flows and consistent with the relatively low
16
autocorrelations in Table 5, the lagged money fund flows do not deliver much predictive power in the
combined model.
Panel D summarizes the regressions for the first overall common factor. The
predictability appears substantial, with an adjusted R-square of 82% in the combined quarterly model
and significant coefficients for BW sentiment, exchange rate, industry production growth, interest rate
spreads, and especially the lagged flows. Thus, the future values of the common factors in mutual
fund flows are persistent and significantly predictable based on current economic conditions.
The significant predictability in common flow factors has a number of implications. To
the extent that aggregate investor behavior as reflected in fund flows can be predicted, this behavior
can be anticipated by policy makers as a function of economic conditions and recent flows. This
might be useful in planning the deployment of regulatory and supervisory resources, for example.
For the mutual fund industry and individual funds, the ability to predict future sales should be useful
for planning marketing strategies, managing cash inventories and forming investment strategy.
Research on financial market efficiency can exploit predictability, as for example, market prices
should respond differently to the expected and unexpected components of fund flows. Finally, the
predictability in common flow factors informs our empirical specifications in the analysis below.
3.6 The Predictive Content of Flows
While the predictability of common flow factors is interesting, the flip side of that
question is also interesting. Is there information in fund flows that is predictive for future economic
and financial market conditions? Table 7 examines whether the first factors can forecast the
macroeconomic and financial variables. We regress the macroeconomc and financial market
variables on their own lagged values and on the lagged flow factors. Panels A, B, C and D use a single
lagged sector flow factor on the right had side, Panel E uses the three sector flows together and Panel
F uses the overall common flow factor. The table reports the coefficient on the lagged flow, its
Newey-West (1980) standard error (using 3 lags for annual data and 6 lags for quarterly data), and the
17
adjusted R-squares of the multiple regressions. These R-squares are sometimes quite high when the
dependent variable is a highly persistent yield or yield spread, so our main interest is the coefficient
and standard error of the lagged flow factor, indicating the marginal predictive ability of the flow for
the economic variable’s AR(1) residuals.
Table 7 suggests that lagged flow factors bear a predictive relation to several of the
variables. In particular, equity and bond fund flow factors predict innovations in the Michigan
sentiment index. There is also significant predictive ability for industrial production growth,
exchange rates, some interest rate spreads, and market volatility. These results suggest that investors,
as reflected in the aggregate flows, may not simply be irrationally chasing the past (performance) as
some authors have believed (e.g., Sapp and Tiwari (2004) and Frazzini and Lamont (2006)). Their
behavior is actually predictive of future economic and financial market conditions.
3.7 Models of Flow Betas
Individual funds' “unconditional” loadings on the common factors have large cross-
sectional variation. For example, the average beta of annual equity fund flows on the first common
factor is about 0.95, but the standard deviation is higher than 3.4. More than 65% of individual funds’
have positive flow betas on the first factor, half of which are significant at the 5% significance level.
As the common factors in fund flows are important, the cross-sectional variation motivates a deeper
analysis of the structure of funds’ flow betas.
We estimate models that allow the flow betas to vary over time and with fund
characteristics. Specifically, using panel data, we estimate:
Fit = ai + G'Xit-1 + Σj (boj + Bj Xit-1) Yjt + uit, (3)
where (boj + Bj Xit-1) is the linear approximation for fund i's flow beta as a function of its predetermined
characteristics, Xit-1 and uit is a regression error. This is similar to the models for equity returns
18
discussed in Rosenberg and Marathe (1979) and Ferson and Harvey (1997). For fund characteristics,
we use fund age, size, the fund family size, the fund’s monthly return volatility over the past two
years, the lagged fund flow and expense ratios as the characteristics. The lagged performance is
measured as a fractional ranking (a number between zero and 1.0) of the average return over the past
year. We also include year or/and fund dummies, considering that uit may include time and fund
fixed effects.
The regression estimates, standard errors and p-values for equity fund flows are
presented in Table 8. The regression models shown in panels (A) through (D) differ in terms of fixed
effects and a focus on retail versus institutional share classes. The coefficients, Bj, on the
characteristics interacted with the flow factors describe the flow betas and the same characteristics
variables appear in the intercept, in the G'Xit-1 term. We include six equity fund flow factors in the
regression but present only the coefficients for the first factor in the table. The G coefficients, shown in
the bottom part of the table, describe relations between fund flows and these characteristics, similar to
what has been documented in previous studies. Previous studies find that young, small, more
expensive and less volatile funds, and funds in larger families, attract more flows other things equal.
Lagged performance enters the flow regression positively and sometimes nonlinearly, although the
coefficient on the squared performance changes with the specification.
There is strong evidence that for retail share classes, flow betas are functions of the
lagged fund characteristics and are time-varying with the funds’ recent performance. The regressions
in Table 8 also show that for retail share classes, young funds, expensive funds and funds with higher
recent flows are more sensitive to the first common flow factor. In particular, flow betas are positive
functions of the lagged performance. Since the flow betas on the first factor roughly represent the
marginal market share of a fund in the sector flows, the coefficients on the squared performance
suggest that some of the nonlinearity in the relation of funds’ flows to past performance is captured in
the flow beta or market share.
A striking finding in Table 8 is the difference between the results for institutional retail
19
share classes. We find virtually no evidence that the flow betas for institutional share classes are
functions of the lagged characteristics or recent performance. There is some relation to lagged
performance in the intercept term. The R-squares also show that the regressions explain less of the
variance of flows for the institutional share classes. To the extent that institutional flows are driven
by defined-contribution retirement accounts, these flows are likely to vary less with economic
conditions, and it makes sense that the response to aggregate flows are insensitive to short term
changes in fund performance or characteristics.
We also find evidence that flow betas for retail share classes are asymmetric, differing
when the aggregate flow is positive or negative. The models allowing for asymmetry are presented
in Table 9. Here we use a piece-wise estimation around zero value of the common flow factor. We
find that the difference between the coefficient estimates on the positive and the negative flow factor
is significant for retail share classes. The effects are interesting, and are illustrated in Figure 5. Here
we graph the fitted fund flow against the aggregate flow factor for retail funds with performance in
the top 25% and bottom 25% of the lagged performance figures. The other variables in the regression
that interact with the flow factor are set equal to their sample means and the variables in the intercept
terms are ignored. The flow betas for the low-performance funds are positive in both regions, but
with smaller slopes when the aggregate flow is positive. Thus, when the aggregate flow is positive
the poorly performing funds get a smaller marginal market share than their share of the loss when the
aggregate flow is negative. The flow betas of the high-performance funds actually change sign,
turning negative when the aggregate flow is negative. Thus, the relations between the fitted and
aggregate flows appear option-like. The high-performing funds appear to be long a straddle on the
aggregate flows, so their expected flows would be enhanced when the aggregate flow is more volatile.
The low-performance funds have flows that appear to be short a put option on the aggregate: when
the aggregate flow is negative they take the brunt of the loss in market share.
4. Applications
20
Using our models of funds’ flow betas and the implied decomposition of fund flows into common
factor and idiosyncratic components, we pursue three applications. First we explore the relation
between flow betas and subsequent fund performance. Then, we revisit the well known flow-
performance relation and the so-called smart money effect.
4.1 Fund Flow Betas and Fund Performance
We conjecture that funds with larger flow betas might deliver relatively poor
performance. Such funds have more pressure to sell their holdings when other funds are selling, and
may realize depressed selling prices at such times. Edelin (1999) finds evidence that equity fund
trades made in response to flows are less profitable than are discretionary trades. The price effect
should be more pronounced relative to the systematic component of flows.
Table 10 summarizes an exercise where we sort equity mutual funds each quarter
according to estimates of their flow betas and examine the subsequent performance of the funds. The
table reports percentage monthly excess returns over the Treasury Bill rate and various alphas for
portfolios of funds formed based on their flow betas on the first common factor for equity mutual
fund flows. At the end of each quarter, t, from 1984 Q3 to 2009 Q3, flow betas on the first factor are
estimated by rolling panel regressions using the data up to that quarter. The factors are estimated
using principal components analysis and data up to the quarter t. The coefficient estimates from the
panel regression, and the fund characteristics in the quarter t, are used to estimate betas on the first
factor for quarter t. Funds are ranked and grouped into five portfolios from low to high according to
the beta estimates. The portfolios of funds are equally-weighted in Panel (A) and TNA-weighted in
Panel (B). The portfolios are rebalanced and the whole procedure is rolled forward every quarter. We
examine the monthly returns on the portfolios in the following quarter following portfolio formation.
Using the time series of returns for the five quintile portfolios we estimate the performance of the
portfolios as the average excess returns over the risk-free rate, the CAPM alpha, the Fama-French
three-factor alpha or the Carhart four-factor alpha. Table 10 reports the estimates, their standard
21
errors and p-values. High - Low is the high flow beta minus the low beta portfolio. The sample
period is from 1982 to 2009 and the first panel regression uses data up to 1983 Q3. The standard errors
are Newey-West estimates with 4 lags.
The first panel of Table 10 shows that high flow-beta funds earn lower average returns
than low flow-beta funds. When the flow betas from Table 8 are used the difference in raw returns is
only 1.4 basis points per month and is not significant. The differences in the alphas are larger, as
much as 13 basis point for the CAPM alphas, but are not significant. However, Table 9 shows that
flow betas are asymmetric and when we allow for asymmetries the effects are stronger. The next
three panels allow for different flow beta functions on three factors, corresponding to aggregate flows
greater than or less than about one standard deviation of the aggregate flow factor. (The flow values
are greater than 0.01 or less than 0.007.) We include a third factor for aggregate flows in between
those tail areas. This exercise reveals that the poor relative performance of high flow-beta funds is
concentrated using the low-aggregate-flow betas. Here the difference between the low and high flow-
beta funds is 24 basis points, which significant at the 10% level. The CAPM and FF3 alpha difference
are larger and significant at the 2% levels. Controlling for Momentum with the Carhart four-factor
model, however, the 17 basis point difference in alphas is not statistically significant. In Panel B the
TNA-weighted portfolios produce similar results.6
4.2 The Flow-Performance Relation
We use the fitted values from the panel regressions in Tables 8 and 9 to decompose the
flows for a given US equity mutual fund into two components. The systematic flow is the fitted flow
beta, (boj + Bj Xit-1) from equation (3), multiplied by the common flow factor, Yjt and summed across the
six common equity flow factors. The idiosyncratic flow is the total net percentage flow for fund i
6 We have also examined annual flows and flow factors with annually rebalanced fund portfolios, where the first panel regression uses data for 1982-1991 and the results are evaluated during 1992-2009. Using the flow betas from Table 8 the raw return difference between low and high flow-beta funds is 14 basis points per month and the CAPM and FF3 alphas are significant at the 5% level for TNA weighted portfolios. The difference are smaller for the equally-weighted portfolios and none of the other differences are significant.
22
minus the common factor part.
We revisit the classical flow-performance relationship documented in the literature
using the two components of flows. Our goal is to distinguish between the responses of idiosyncratic
flows and systematic flows to past performance. Given that most of the literature looks at retail
investors' money flows into equity mutual funds, we restrict our analysis to equity fund flows. We
also look separately at institutional and retail share classes.
We find, but do not report in the tables, that the two components of fund flows appear to
respond differently to past fund performance. Both components are positively related to lagged
performance but the coefficient for the common part is about three times as large on average. The
common part of flows has a weak negative relation to the squared past performance, while the
idiosyncratic part has a positive relation on average. Furthermore, the relation of the idiosyncratic
part of flows to lagged performance and the other control variables is relatively stable in subsamples,
whereas the common factor component presents less stable relations. Kim (2011) finds that the flow
performance relation changes around the year 2000 from a convex relation in the earlier years to a
linear or even concave relation after 2000. Our results suggest that it is the common factor component
of flows driving these changes, while the relation of the idiosyncratic part of flows to past
performance remains convex and stable during the sample. Thus, the decomposition into common
and idiosyncratic flow factors helps to dissect the dynamics of the flow performance relation.
4.3 The Smart Money Effect
Gruber (1996) and Zheng (1999) find that funds with money inflows subsequently
perform better during the next quarter than funds with outflows. Sapp and Tiwari (2004) confirm
these findings, but note that the differences are not significant when adjusted for Momentum using
the Carhart four-factor model. We replicate these exercises with our data and find similar results.
The smart money effect is stronger when the portfolios weighted according to fund flows are
rebalanced quarterly than when held for a year. However, when we use the two components of fund
23
flows we find that the smart money effect, to the extent that it exists, is concentrated in the common
factor part of funds’ flows. We find little relation using the idiosyncratic flows. This reinforces the
interpretation that the smart money effect has less to do with investors picking out idiosyncratically
good funds, and more with systematic factors such as momentum.
5. Conclusions
The determinants of the flows of money into mutual funds are important to understand, as mutual
funds are significant in consumer savings, and as a window into individuals' investment decisions,
fund manager's incentives and the efficiency of financial markets. This paper explores mutual fund
flows, decomposing the flows into their common factors and idiosyncratic components, and modeling
funds’ “flow betas,” or the sensitivity of their flows to common flow factors.
The systematic components of fund flows capture significant fractions of the variation
in individual fund flows over time. Unlike asset market prices, which the finance literature finds
difficult to explain, the common factors in mutual fund flows respond strongly to macroeconomic
conditions. The common flow factors are also predictable, displaying significant and complex
autocorrelation structure and relations to lagged macroeconomic and financial market variables.
Lagged flows also bear a predictive relation to future economic conditions, suggesting that in the
aggregate fund investors do not simply chase the past (performance), but look to the future in their
investment decisions.
There is substantial variation across individual mutual funds in the sensitivity of their
flows to the common flow factors. These flow betas may be roughly interpreted as the marginal
market share of new sector flows that a fund receives. We find that flow betas can be modeled as
functions of the characteristics of a fund such as its size, age, expense ratio and recent return
performance. These functions are asymmetric. High-performing funds have lower or even negative
flow betas when the aggregate flow is negative. Thus, when flows are strong, high performing funds
increase their market share and when there are negative sector flows, funds with weaker recent return
24
performance lose the most market share.
Equity funds with higher flow betas on large sector outflows offer lower subsequent
performance. Such funds have to sell assets when other funds in the sector are selling. This adds a
new dimension to the “fire sales” phenomenon studied by Coval and Stafford (2007), who examined
the individual stocks held by funds experiencing large negative total flows.
Studying the common and idiosyncratic components of funds’ flows refines our
understanding of other stylized facts in the mutual fund literature. One is the “flow-performance”
relation documented by Ippolitto (1992), Sirri and Tufano (1998) and Chevalier and Ellison (1997).
Here we find that common and idiosyncratic flows behave differently in flow-performance
regressions, and these differences are related to changes in the overall relation over time. A second
application is the "smart money" effect of Gruber (1996), who finds that new money flows into US
equity mutual funds earn higher returns than existing shareholders. We find that this effect is
concentrated in the common factor component of fund flows. We believe that future research
comparing common and idiosyncratic fund flows should lead to further significant refinements of our
understanding.

*Note: The sample correlation between the first common factors and the macroeconomic and financial variables are denoted as ρ. The p-values are computed using the t-distribution with (T-2) degree of freedom for the statistic (T-2)1/2 ([(ρ2)/(1-ρ2)])1/2 where T is the number of time periods. The factors are extracted using asymptotic principal components analysis on fund flows. Panel (D) uses the Goyal et al (2008) method. The Michigan sentiment index is the consumer confidence index from the University of Michigan, and ∆Michigan sentiment is the change in the log of the index. BW sentiment is the variable constructed in Baker and Wurgler (2006). Inflation is the change in log of the consumer price index. Exchange rate is the change in log of the major foreign exchange index. Industrial production growth is the change in log of the index from Federal Reserve Bank of St. Louis Economic data (FRED). Disposable income growth is the change in log of disposable personal income per capita from FRED. Market volatility and return are the standard deviation and the return on S&P500 index respectively, which are obtained using its daily data. D/P ratio is the dividend to price ratio of the value weighed CRSP index. TBill is the yield on the 3-month Treasury bill. Treasury10year is the yield on the 10-year Treasury bond. The sample period is annual, from 1981 to 2009 for US equity funds and from 1992 to 2009 for US bond funds and US money market funds.

*Note: The independent variables are the common factors extracted using a principal components analysis on fund flows for a given sector. Panel (D) combines sectors using the Goyal et al (2008) method. The independent variables are the macro variables and financial variables as listed in the first column. ∆Michigan sentim is the change of the log of the Michigan sentiment index as surveyed by the University of Michigan. BW sentiment is the variable constructed in Baker and Wurgler (2006). Inflation is the change in log of the consumer price index. Exchange rate is the change in log of the major foreign exchange index. IP growth is the change in log of US industrial production. Disp income growth is the change in log of personal disposable income per capita. Market volatility and return are the standard deviation and the return on S&P500 index respectively, which are obtained using its daily data. d/p ratio is the dividend to price ratio of the value weighted CRSP index. T bill is the yield on the 3-month Treasury bill. 10yr is the yield on the 10-year Treasury bond. The tables report the coefficient estimates and their t-ratios, where the standard errors are Newey-West estimates with 2 lags for annual data and 5 lags for quarterly data. The sample includes US equity mutual funds, US bond funds, and US money market funds that have at least 5 million dollars of assets under management at the beginning of the periods and are at least one-year old. The sample period is from 1980 Q1 to 2009 Q4 for US equity funds and from 1991 Q1 to 2009 Q4 for US bond funds and US money market funds.

*Note: The autocorrelations ρ are shown with p-values in parentheses, calculated assuming that (T-2)1/2 ([(ρ2)/(1-ρ2)])1/2 is distributed according to the t-distribution with (T-2) degree of freedom where T is the number of time periods. The common factors are extracted using a principal components analysis on fund flows for funds in the given sector. The combined sector factors use the Goyal et al (2008) method. The sample includes US equity mutual funds, US bond funds, and US money market funds that have at least 5 million dollars in assets under management at the beginning of the period and are at least one-year old. The sample periods are from 1980 to 2009 for equity funds and from 1991 to 2009 for bond funds and money market funds.

*Note: The dependent variable is the net flow into an equity fund in calendar year t. The independent variables are the first common factor for year t (f1), fund performance and characteristics in the year t-1, fund performance in t-2, and interaction terms between the first common factor and the fund variables as listed in the first column. The independent variables also include a constant, the common factors from f2 to f6 and their interaction terms with the fund variables (not presented). The tables report the coefficient estimates, their standard errors and p-values. The standard errors in (A) and (C) are clustered by year and (B) and (D) by year and fund. Performance is measured as the ranking based on lagged annual returns divided by the number of sample funds in each period. Age is the log of the years since the inception date of fund or the first date that the fund return data is available if earlier. Size is the log of TNA of a fund divided by the average TNA of equity mutual funds, including index funds. Expense ratio is the expense ratio for the most recent fiscal year as reported in the fund prospectus and does not include load fees. Volatility is the standard deviation of the monthly return of a fund over the last two years. Family size is the log of size of the family divided by the average size of families. Size of a family is the sum of the total net assets of the funds belonging to the same advisor. The sample period is from 1982 to 2009.

Note: The table reports monthly excess returns (%) over the Treasury Bill rate and alphas (%) for portfolios of funds formed based on betas on the first common factor for equity mutual fund flows. At the end of each quarter from 1984 Q3 to 2009 Q3, flow betas on the first factor are estimated by rolling panel regressions using the data up to that quarter. The panel regression varies in two ways: (1) the linear specification for the first factor f1; and (2) a piecewise linear specification with three factors, defined as {f1>0.1,-0.007<f1 <0.1 and f1< -0.007}. The sample
50
mean flow minus the standard deviation of f1 is about -0.007. The coefficient estimates obtained from the panel regression, fund characteristics in the quarter t and the first factor are used to estimate betas on the first factor. The first factor is estimated using the principal component analysis and the data up to the quarter t. Funds are ranked and grouped into five portfolios from low to high according to the beta estimates for year t. The portfolios of funds are size-weighted in Panel (A) and equally-weighted in Panel (B). The portfolios are rebalanced every quarter. We use monthly returns on the portfolios in the following quarter and estimate the performance of these portfolios as the average excess returns over the risk-free rate, CAPM alphas, Fama-French three-factor alphas and Carhart four-factor alphas. The table reports the estimates, standard errors and their p-values. High - Low reports the estimates on the High minus Low portfolios. Numbers in bold represent significance at a 10% level. The sample period is from 1982 to 2009 and the first panel regression uses data up to 1983 Q3. The standard errors Newey-West estimates with 4 lags.

*Note: The table reports the autocorrelation of the variables listed in the first column. Inflation is the change in log of the consumer price index. Exchange rate is the change in log of the major foreign exchange index. Michigan sentiment index is the consumer confidence index as surveyed by the University of Michigan, and ∆Michigan sentiment is the change of the log of the index. BW sentiment is the variable constructed in Baker and Wurgler (2006) and BW sentiment change is its first difference. IP growth is the change in log of the industry production. Market volatility and return are the standard deviation and the return on S&P500 index respectively, which are obtained using its daily data. dp ratio is the dividend to price ratio of the value weighed CRSP index. 10yr is the yield on the 10-tear Treasury bond. The sample period is from 1980 Q1 to 2009 Q4 except for BW sentiment and BW sentiment change, which are from 1980 Q1 to 2006 Q4.

*Note: The figures plot the ratios of eigenvalues obtained from principal components analysis. The sample period is from 1981 to 2009 (annual) and from 1981 Q4 to 2009 Q4 (quarterly) for equity fund flows and from 1992 to 2009 (annual) and from 1992 Q4 to 2009 Q4 (quarterly) for bond fund flows, money market flows. The “full” method uses the whole sample period and the rolling method uses overlapping rolling samples of 12 years or 48 quarters. The sample includes the net flows of individual funds that have at least 5 million dollars in assets under management at the beginning of the period and are at least 1-year old.

*Note: The eigenvalues of the matrix formed as the sum of the combined eigenprojections from each sector (equity, bond, and money market fund flows). For equity funds we use the first six factors, for bond funds the first three factors, and for money market funds the first two factors. Quarterly flows are residual flows after regressing net flows on quarterly dummies (without the intercept). The sample period is from 1992 to 2009 (annual) and from 1992 Q4 to 2009 Q4 (quarterly). The sample includes the net flows of individual funds that have at least 5 million dollars in assets under management at the beginning of the period and are at least 1-year old.

Note: The figures plot the first common factor extracted using principal components analysis or the Goyal et al
62
(2008) method. The “full” examples use the whole sample period and “rolling” uses overlapping rolling samples of 12 years or 48 quarters. The factor is scaled so that the value-weighted sector flows have the coefficient estimate on the factor equal to one. The sample period is 1981 to 2009 for the equity sector and from 1992 to 2009 for the others. The vertical shaded bars indicate recession periods as defined by the National Bureau of Economic Research.

Figure 5. The first common equity flow factor and the average flows into groups formed by performance ranking
Note: The top figure plots the first common equity factor and the average flows into each group formed based on lagged performance (return relative to the CSRP VW index) ranking. Group 1 is the lowest group and 3 is the highest group. Similarly, the bottom figure plots the first common equity factor and the average betas of each group. Group 2 is not shown. The data period is from 1981 to 2009.
