INTRODUCTION:
The financial market is the driver of the economic growth and
development of any country. A sound financial market can take the country to
the apex. Financial resources were by allocating the resources through one of
the ways such as portfolios, which are combinations of various securities.
Portfolio analysis includes analyzing the range of possible portfolios that can
be constituted from a given set of securities.
A combination of securities with different risk- return characteristics will
constitute the portfolio of the investor. A portfolio is a combination of various
assets and/or instruments of investments. The portfolio is also built up out of
the wealth or income of the investor over a period of time with a view to suit
his risk and return preferences to that of the portfolio that he holds. The
portfolio analysis is an analysis of the risk-return characteristics of individual
securities in the portfolio and changes that may take place in combination with
other securities due to interactions among themselves and impact of each one
of them on others.
As individuals are becoming more and more responsible for ensuring
their own financial future, portfolio or fund management has taken on an
increasingly important role in banks ranges of offerings to their clients. In
addition, as interest rates have come down and the stock market has gone up
and come down again, clients have a choice of leaving their saving in deposit
accounts, or putting those savings in unit trusts or investment portfolios which
invest in equities and/or bonds. Investing in unit trusts or mutual funds is one
way for individuals and corporations alike to potentially enhance the returns
on their saving

RESEARCH METHODOLOGY:
Research design or research methodology is the procedure of collecting,
analyzing and interpreting the data to diagnose the problem and react to the
opportunity in such a way where the costs can be minimized and the desired
level of accuracy can be achieved to arrive at a particular conclusion.
The methodology used in the study for the completion of the project and the
fulfillment of the project objectives, is as follows:
Market prices of the companies have been taken for the years of
different dates, there by dividing the companies into 5 sectors.
A final portfolio is made at the end of the year to know the changes
(increase/decrease) in the portfolio at the end of the year.
Sources of the data:
Primary data:
The primary data information is gathered from SMC fin polis by interviewing
SMC executives.
Secondary data:
The secondary data is collected from various financial books, magazines and

INDUSTRY PROFILE
Bombay Stock Exchange Limited is the oldest stock exchange in Asia with a
rich heritage. Popularly known as "BSE", it was established as "The Native
Share & Stock Brokers Association" in 1875. BSE has played a pioneering
role in the Indian Securities Market - one of the oldest in the world. Much
before actual legislations were enacted, BSE had formulated comprehensive
set of Rules and Regulations for the Indian Capital Markets. It also laid down
best practices adopted by the Indian Capital Markets after India gained its
Independence.
Vision:
"Emerge as the premier Indian stock exchange by establishing global
benchmarks"
BSE is the first stock exchange in the country to obtain permanent
recognition in 1956 from the Government of India under the Securities
Contracts (Regulation) Act, 1956.The Exchange's pivotal and pre-eminent role
in the development of the Indian capital market is widely recognized and its
index, SENSEX, is tracked worldwide. SENSEX, first compiled in 1986 was
calculated on a "Market Capitalization-Weighted" methodology of 30
component stocks representing a sample of large, well-established and
financially sound companies. The base year of SENSEX is 1978-79. From
September 2003, the SENSEX is calculated on a free-float market
capitalization methodology. The "free-float Market Capitalization-Weighted"
7

methodology is a widely followed index construction methodology on which
majority of global equity benchmarks are based.
The launch of SENSEX in 1986 was later followed up in January 1989 by
introduction of BSE National Index (Base: 1983-84 = 100). It comprised of 100
stocks listed at five major stock exchanges in India at Mumbai, Calcutta,
Delhi, Ahmadabad and Madras. The BSE National Index was renamed as
BSE-100 Index from October 14, 1996 and since then it is calculated taking
into consideration only the prices of stocks listed at BSE. The Exchange
launched dollar-linked version of BSE-100 index i.e. Dollex-100 on May 22,
2006. The Exchange constructed and launched on 27th May, 1994, two new
index series viz., the 'BSE-200' and the 'DOLLEX-200' indices. The launch of
BSE-200 Index in 1994 was followed by the launch of BSE-500 Index and 5
sectored indices in 1999. In 2001, BSE launched the BSE-PSU Index,
DOLLEX-30 and the country's first free-float based index - the BSE TECK
Index. The Exchange shifted all its indices to a free-float methodology (except
BSE PSU index).
The Exchange has a nation-wide reach with a presence in 417 cities and
towns of India. The systems and processes of the Exchange are designed to
safeguard market integrity and enhance transparency in operations. During
the year 2004-2005, the trading volumes on the Exchange showed robust
growth.
The Exchange provides an efficient and transparent market for trading in
equity, debt instruments and derivatives. The BSE's On Line Trading System
(BOLT) is a proprietary system of the Exchange and is BS 7799-2-2002

The Exchange is professionally managed under the overall direction of the
Board of Directors. The Board comprises eminent professionals,
representatives of Trading Members and the Managing Director of the
Exchange. The Board is inclusive and is designed to benefit from the
participation of market intermediaries.

In 2002, the name The Stock Exchange, Mumbai, was changed to BSE.
BSE, which had introduced securities trading in India, replaced its open
outcry system of trading in 1995, when the totally automated trading
through the BSE Online trading (BOLT) system was put into practice. The
BOLT network was expanded, nationwide, in 1997. It was at the BSE's
International Convention Hall that Indias 1st Bell ringing ceremony in the
history Capital Markets was held on February 18th, 2002. It was the listing
ceremony of Bharti Tele ventures Ltd.
BSE with its long history of capital market development is fully geared to

report of the High Powered Study Group on Establishment of New Stock

Wholesale Debt Market (WDM) segment in June 1994. The Capital Market
(Equities) segment commenced operations in November 1994 and operations
in Derivatives segment commenced in June 2000.

country. NSE is setting the agenda for change in the securities markets in
India. For last 5 years it has played a major role in bringing investors from 347
cities and towns online, ensuring complete transparency, introducing financial
guarantee to settlements, ensuring scientifically designed and professionally
managed indices and by nurturing the dematerialization effort across the
country.

OVER THE COUNTR EXCHANGE OF INDIA
OTCEI was incorporated in 1990 as a section 25 company under the
companies Act 1956 and is recognized as a stock exchange under section 4
of the securities Contracts Regulation Act, 1956. The exchange was set up to
aid enterprising promotes in raising finance for new projects in a cost effective
manner and to provide investors with a transparent and efficient mode of
trading Modeled along the lines of the NASDAQ market of USA, OTCEI
introduced many novel concepts to the Indian capital markets such as screen-
based nationwide trading, sponsorship of companies, market making and
scrip less trading. As a measure of success of these efforts, the Exchange
today has 115 listings and has assisted in providing capital for enterprises that
have gone on to build successful brands for themselves like VIP Advanta,
Sonora Tiles & Brilliant mineral water, etc.
Need for OTCEI:
12

8/2/2019 Risk Portfolio Management
13/84
Studies by NASSCOM, software technology parks of India, the venture
capitals funds and the governments IT tasks Force, as well as rising interest
in IT, Pharmaceutical, Biotechnology and Media shares have repeatedly
emphasized the need for a national stock market for innovation and high
growth companies.
Innovative companies are critical to developing economics like India, which is
undergoing a major technological revolution. With their abilities to generate
employment opportunities and contribute to the economy, it is essential that
these companies not only expand existing operations but also set up new
units. The key issue for these companies is raising timely, cost effective and
long term capital to sustain their operations and enhance growth. Such
companies, particularly those that have been in operation for a short time, are
unable to raise funds through the traditional financing methods, because they
have not yet been evaluated by the financial world.
Who would find OTCEI helpful?
High-technology enterprises
Companies with high growth potential
Companies focused on new product development
Entrepreneurs seeking finance for specific business projects
The Indian economy is demonstrating signs of recovery and it is essential that
these companies have suitable financing alternative to fund their growth and
maintain competitiveness.

OTCEI, With its entry guidelines and eligibility requirement tailored for such
innovative and growth oriented companies, is ideally positioned as the
preferred route for raising funds through initial public offer(IPOs) or primary
issues, in this country.

REVIEW OF LITERATURE
INTRODUCTION:
A portfolio is a collection of investments held by an institution or a
private individual. In building up an investment portfolio a financial institution
will typically conduct its own investment analysis, whilst a private individual
may make use of the services of a financial advisor or a financial institution
which offers portfolio management services. Holding a portfolio is part of an
investment and risk-limiting strategy called diversification. By owning several
assets, certain types of risk (in particular specific risk) can be reduced. The
23
-
8/2/2019 Risk Portfolio Management
24/84
assets in the portfolio could include stocks, bonds, options, warrants, gold
certificates, real estate, futures contracts, production facilities, or any other
item that is expected to retain its value.
Portfolio management involves deciding what assets to include in the
portfolio, given the goals of the portfolio owner and changing economic
conditions. Selection involves deciding what assets to purchase, how many to
purchase, when to purchase them, and what assets to divest. These
decisions always involve some sort of performance measurement, most
typically expected return on the portfolio, and the risk associated with this
return (i.e. the standard deviation of the return). Typically the expected returns
from portfolios, comprised of different asset bundles are compared.
The unique goals and circumstances of the investor must also be considered.
Some investors are more risk averse than others. Mutual funds have
developed particular techniques to optimize their portfolio holdings.
Thus, portfolio management is all about strengths, weaknesses,
opportunities and threats in the choice of debt vs. equity, domestic vs.
international, growth vs. safety and numerous other trade-offs encounteredin the attempt to maximize return at a given appetite for risk.
Aspects of Portfolio Management:
Basically portfolio management involves
A proper investment decision making of what to buy & sell
Proper money management in terms of investment in a basket of
assets so as to satisfy the asset preferences of investors.

Reduce the risk and increase returns.
OBJECTIVES OF PORTFOLIO MANAGEMENT:
The basic objective of Portfolio Management is to maximize yield and
minimize risk. The other ancillary objectives are as per needs of investors,
namely:
Regular income or stable return
Appreciation of capital
Marketability and liquidity
Safety of investment
Minimizing of tax liability.
NEED FOR PORTFOLIO MANAGEMENT:
The Portfolio Management deals with the process of selection securities from
the number of opportunities available with different expected returns and
carrying different levels of risk and the selection of securities is made with a
view to provide the investors the maximum yield for a given level of risk or
ensure minimum risk for a level of return.
Portfolio Management is a process encompassing many activities of
investment in assets and securities. It is a dynamics and flexible concept and
involves regular and systematic analysis, judgment and actions. The
objectives of this service are to help the unknown investors with the expertise
of professionals in investment Portfolio Management. It involves construction
of a portfolio based upon the investors objectives, constrains, preferences for
risk and return and liability. The portfolio is reviewed and adjusted from time to
25
-
8/2/2019 Risk Portfolio Management
26/84
time with the market conditions. The evaluation of portfolio is to be done in
terms of targets set for risk and return. The changes in portfolio are to be
effected to meet the changing conditions.
Portfolio Construction refers to the allocation of surplus funds in hand among
a variety of financial assets open for investment. Portfolio theory concerns
itself with the principles governing such allocation. The modern view of
investment is oriented towards the assembly of proper combinations held
together will give beneficial result if they are grouped in a manner to secure
higher return after taking into consideration the risk element.
The modern theory is the view that by diversification, risk can be reduced. The
investor can make diversification either by having a large number of shares of
companies in different regions, in different industries or those producing
different types of product lines. Modern theory believes in the perspectives of
combination of securities under constraints of risk and return.
ELEMENTS:
Portfolio Management is an on-going process involving the following basic
tasks.
Identification of the investors objective, constrains and preferences
which help formulated the invest policy.
Strategies are to be developed and implemented in tune with invest
policy formulated. This will help the selection of asset classes and
securities in each class depending upon their risk-return attributes.
26
-

27/84
Review and monitoring of the performance of the portfolio by
continuous overview of the market conditions, companys performance
and investors circumstances.
Finally, the evaluation of portfolio for the results to compare with the
targets and needed adjustments have to be made in the portfolio to the
emerging conditions and to make up for any shortfalls in achievements
(targets).

six-stage process helps ensure that the investments match investors unique
needs, both now and in the future.
1. IDENTIFY GOALS AND OBJECTIVES:
When will you need the money from your investments? What are you
saving your money for? With the assistance of financial advisor, the
Investment Profile Questionnaire will guide through a series of questions
to help identify the goals and objectives for the investments.
2. DETERMINE OPTIMAL INVESTMENT MIX:
Once the Investment Profile Questionnaire is completed, investors optimal
investment mix or asset allocation will be determined. An asset allocation
represents the mix of investments (cash, fixed income and equities) that
match individual risk and return needs.
This step represents one of the most important decisions in your
portfolio construction, as asset allocation has been found to be the major
determinant of long-term portfolio performance.
29
-
8/2/2019 Risk Portfolio Management
30/84
3. CREATE A CUSTOMIZED INVESTMENT POLICY STATEMENT
When the optimal investment mix is determined, the next step is to
formalize our goals and objectives in order to utilize them as a benchmark
to monitor progress and future updates.
4. SELECT INVESTMENTS
The customized portfolio is created using an allocation of select QFM
Funds. Each QFM Fund is designed to satisfy the requirements of a
specific asset class, and is selected in the necessary proportion to match
the optimal investment mix.5 MONITOR PROGRESS
Building an optimal investment mix is only part of the process. It is equally
important to maintain the optimal mix when varying market conditions
cause investment mix to drift away from its target. To ensure that mix of
asset classes stays in line with investors unique needs, the portfolio will
be monitored and rebalanced back to the optimal investment mix
6. REASSESS NEEDS AND GOALS
Just as markets shift, so do the goals and objectives of investors. With the
flexibility of the Portfolio Program andAsset Management Program, when
the investors needs or other life circumstances change, the portfolio has
the flexibility to accommodate such changes.
RISK:
Risk refers to the probability that the return and therefore the value of an
asset or security may have alternative outcomes. Risk is the uncertainty
30
-
8/2/2019 Risk Portfolio Management
31/84
(today) surrounding the eventual outcome of an event which will occur in the
future. Risk is uncertainty of the income/capital appreciation or loss of both.
All investments are risky. The higher the risk taken, the higher is the return.
But proper management of risk involves the right choice of investments whose
risks are compensation.
RETURN:
Return-yield or return differs from the nature of instruments, maturity period
and the creditor or debtor nature of the instrument and a host of other factors.
The most important factor influencing return is risk return is measured by
taking the price income plus the price change.
PORTFOLIO RISK:
Risk on portfolio is different from the risk on individual securities. This risk is
reflected by in the variability of the returns from zero to infinity. The expected
return depends on probability of the returns and their weighted contribution to
the risk of the portfolio.
RETURN ON PORTFOLIO:
Each security in a portfolio contributes returns in the proportion of its
investment in security. Thus the portfolio of expected returns, from each of the
securities with weights representing the proportionate share of security in the
total investments.
RISK RETURN RELATIONSHIP:
31
-
8/2/2019 Risk Portfolio Management
32/84
The risk/return relationship is a fundamental concept in not only financial
analysis, but in every aspect of life. If decisions are to lead to benefit
maximization, it is necessary that individuals/institutions consider the
combined influence on expected (future) return or benefit as well as on
risk/cost. The requirement that expected return/benefit be commensurate with
risk/cost is known as the "risk/return trade-off" in finance.
All investments have some risks. An investment in shares of companies has
its own risks or uncertainty. These risks arise out of variability of returns or
yields and uncertainty of appreciation or depreciation of share prices, loss of
liquidity etc. and the overtime can be represented by the variance of the
returns. Normally, higher the risk that the investors take, the higher is the
return.
.
.
TYPES OF RISKS: risk consists of two components. They are
32
-
8/2/2019 Risk Portfolio Management
33/84
1. Systematic Risk2. Un-systematic Risk
1. SYSTEMATIC RISK:
Systematic risk refers to that portion of total variability in return caused by
factors affecting the prices of all securities. Economic, Political and
sociological changes are sources of systematic risk. Their effect is to cause
prices of nearly all individual common stocks and/or all individual bonds to
move together in the same manner.
i. Market Risk:
Variability in return on most common stocks that are due to basic sweeping
changes in investor expectations is referred to as market risk. Market risk is
caused by investor reaction to tangible as well as intangible events.
ii. Interest rate-Risk:
Interest rate risk refers to the uncertainty of future market values and of the
size of future income, caused by fluctuations in the general level of interest
rates.
iii. Purchasing-Power Risk:
Purchasing power risk is the uncertainty of the purchasing power of the
amounts to be received. In more events everyday terms, purchasing power
risk refers to the impact of or deflation on an investment.
2. UNSYSTEMATIC RISK:
Unsystematic risk is the portion of total risk that is unique to a firm or industry.
33
-
8/2/2019 Risk Portfolio Management
34/84
Factors such as management capability, consumer preferences, and labor
strikes Cause systematic variability of return in a firm. Unsystematic factors
are largely independent of factors affecting securities markets in general.
Because these factors affect one firm, they must be examined for each firm.
Unsystematic risk that portion of risk that is unique or peculiar to a firm or
an industry, above and beyond that affecting securities markets in general.
Factors such as management capability, consumer preferences, and labor
strikes can cause unsystematic variability of return for a companys stock.
i. Business Risk:
Business risk is a function of the operating conditions faced by a firm and the
variability these conditions inject into operating income and expected
dividends.
Business risk can be divided into two broad categories
a. Internal Business Risk
b. External Business Risk
a. Internal business risk is associated with the operational efficiency of the
firm. The operational efficiency differs from company to company. The
efficiency of operation is reflected on the companys achievement of its
pre-set goals and the fulfillment of the promises to its investors.
b. External business risk is the result of operating conditions imposed on
the firm by circumstances beyond its control. The external environments in
which it operates exert some pressure on the firm. The external factors are
34
-
8/2/2019 Risk Portfolio Management
35/84
social and regulatory factors, monetary and fiscal policies of the
government, business cycle and the general economic environment within
which a firm or an industry operates.
ii. Financial Risk:
Financial risk is associated with the way in which a company finances its
activities. Financial risk is avoided risk to the extent that management has the
freedom to decide to borrow or not to borrow funds. A firm with no debit
financing has no financial risk
MARKOWITZ MODEL
THE MEAN VARIANCE CRITERION:
Dr. Harry M. Markowitz is credited with developing the first modern portfolio
analysis model in order to arrange for the optimum allocation of assets with in
portfolio. To reach these objectives, Markowitz generated portfolio with in a
reward risk context. In essence, Markowitz model is a theoretical framework
for the analysis of risk return choices. Decisions are based on the concept of
efficient portfolios.
Markowitz model is a theoretical framework for the analysis of risk, return
choices and this approach determines an efficient set of portfolio return
through three important variable that is,
Return
Standard Deviation
Coefficient of correlation
Markowitz model is also called as a Full Covariance Model. Through this
model the investor can find out the efficient set of portfolio by finding out the
tradeoff between risk and return, between the limits of zero and infinity.

According to this theory, the effect of one security purchase over the effects of
the other security purchase is taken into consideration and then the results
are evaluated. Markowitz had given up the single stock portfolio and
introduced diversification. The single stock portfolio would be preferable if the
investor is perfectly certain that his expectation of highest return would turn
out to be real. In the world of uncertainty, most of the risk averse investors
would like to join Markowitz rather than keeping a single stock, because
diversification reduces the risk.
A portfolio is efficient when it is expected to yield the highest return for the
level of risk accepted or, alternatively the smallest portfolio risk for a specified
level of expected return level chosen, and asset are substituted until the
portfolio combination expected returns, set of efficient portfolio is generated.
Assumptions:
The Markowitz model is based on several assumptions regarding investor
behavior:
1. Investors consider each investment alternative as being represented by
a probability distribution of expected returns over some holding period.
2. Investors maximize one period-expected utility and possess utilitycurve, which demonstrates diminishing marginal utility of wealth.
3. Individuals estimate risk on the basis of variability of expected return.
4. Investors base decisions solely on expected return and variance of
return only.
36
-
8/2/2019 Risk Portfolio Management
37/84
5. For a given risk level, investors prefer high returns to lower returns.
Similarly for a given level of expected return, investors prefer less risk
to more risk.
Under these assumptions, a single asset or portfolio of assets is considered to
be efficient if no other asset or portfolio of assets higher expected return with
the same expected return.
THE SPECIFIC MODEL:
In developing this model, Markowitz first disposed of the investor behavior
rule that the investor should maximize expected return. This rule implies non-
diversified single security analysis portfolio with the highest expected return is
the most desirable portfolio. Only by buying that single security portfolio would
obviously be preferable if the investor were perfectly certain that this highest
expected return would turn out to be the actual return. However, under real
world conditions of uncertainty, most risk adverse investors join with
Markowitz in discarding the role of calling for maximizing the expected
returns. As an alternative, Markowitz offers the expected returns/variance
rule.
Markowitz has shown the effect of diversification by regarding the risk of
securities. According to him, the security with the covariance, which is either
negative or low amongst them, is the best manner to reduce risk. Markowitz
has been able to show that securities, which have, less than positive
correlation will reduce risk without, in any way, bringing the return down.
According to his research study a low correlation level between securities in
the portfolio will show less risk. According to him, investing in a large number
37

of securities is not the right method of investment. It is the right kind of
security that brings the maximum results.
Henry Markowitz has given the following formula for a two-security portfolio
and three security portfolios.
= (x1)2 (1)2 + (X2)2(2)2 + 2(X1)(X2)(r12)(1) (2)
= (x1)2(1)2+(X2)2(2)2 + (X3)2(3)2 +2(X1)(X2)(r12)(1) (2)+ 2(X1)(X3)(r13)(1)

CAPITAL ASSET PRICING MODEL: (CAPM)
38
-
8/2/2019 Risk Portfolio Management
39/84
The CAPM is a model for pricing an individual security (asset) or a
portfolio. For individual security perspective, the security market line (SML) is
used and its relation to expected return and systematic risk (beta) to show
how the market must price individual securities in relation to their security risk
class. The SML enables us to calculate the reward-to-risk ratio for any
security in relation to that of the overall market. Therefore, when the expected
rate of return for any security is deflated by its beta coefficient, the reward-to-
risk ratio for any individual security in the market is equal to the market
reward-to-risk ratio, thus:
Individual securitys / beta = Markets securities (portfolio)
Reward-to-risk ratio Reward-to-risk ratio
,
The Security Market Line, seen here in a graph, describes a relation between
the beta and the asset's expected rate of return

The market reward-to-risk ratio is effectively the market risk premium and by
rearranging the above equation and solving for E (Ri), we obtain the Capital
Asset Pricing Model (CAPM).
Where:
is the expected return on the capital asset
is the risk-free rate of interest
(the beta coefficient) the sensitivity of the asset returns to market
returns, or also ,
is the expected return of the market
is sometimes known as the market premium orrisk premium
(the difference between the expected market rate of return and the risk-free
rate of return).
Beta measures the volatility of the security, relative to the asset class. The
equation is saying that investors require higher levels of expected returns to
compensate them for higher expected risk. We can think of the formula as
predicting a security's behavior as a function of beta:
CAPM says that if we know a security's beta then we know the value
of r that investors expect it to have.

Assumptions of CAPM:
All investors have rational expectations.
There are no arbitrage opportunities.
Returns are distributed normally.
Fixed quantity ofassets.
Perfectly efficient capital markets.
Investors are solely concerned with level and uncertainty of future
wealth
Separation of financial and production sectors. Thus, production plans
are fixed.
Risk-free rates exist with limitless borrowing capacity and universal
access.
The Risk-free borrowing and lending rates are equal.
No inflation and no change in the level of interest rate exists.
Perfect information, hence all investors have the same expectations
about security returns for any given time period.
S hortcomings Of CAPM:
The model assumes that asset returns are (jointly) normally distributed
random variables. It is however frequently observed that returns in
equity and other markets are not normally distributed.
The model assumes that the variance of returns is an adequate
measurement of risk.

The model does not appear to adequately explain the variation in stock
returns.
The model assumes those given a certain expected return investors
will prefer lower risk (lower variance) to higher risk and conversely
given a certain level of risk will prefer higher returns to lower ones.
The model assumes that all investors have access to the same
information and agree about the risk and expected return of all assets.
(Homogeneous expectations assumption)
The model assumes that there are no taxes or transaction costs.
The market portfolio consists of all assets in all markets, where each
asset is weighted by its market capitalization. This assumes no
preference between markets and assets for individual investors, and
that investors choose assets solely as a function of their risk-return
profile. It also assumes that all assets are infinitely divisible as to the
amount which may be held or transacted.
The market portfolio should in theory include all types of assets that are
held by anyone as an investment (including works of art, real estate,
human capital...)
Unfortunately, it has been shown that this substitution is not innocuous
and can lead to false inferences as to the validity of the CAPM, and
it has been said that due to the in observability of the true market
portfolio, the CAPM might not be empirically testable.

The efficient frontier:
The CAPM assumes that the risk-return profile of a portfolio can be optimized
- an optimal portfolio displays the lowest possible level of risk for its level of
return. Additionally, since each additional asset introduced into a portfolio
further diversifies the portfolio, the optimal portfolio must comprise every
asset, with each asset value-weighted to achieve the above. All such optimal
portfolios, i.e., one for each level of return, comprise the efficient frontier.
A line created from the risk-reward graph, comprised of optimal portfolios.
The optimal portfolios plotted along the curve have the highest expected
return possible for the given amount of risk.

Because the un systemic risk is diversifiable, the total risk of a portfolio can be
viewed as beta.
Note 1: The expected market rate of return is usually measured by
looking at the arithmetic average of the historical returns on a market
portfolio.
Note 2: The risk free rate of return used for determining the risk premium
is usually the arithmetic average of historical risk free rates of return andnot the current risk free rate of return.
Measuring the Expected Return and Standard Deviation of a Portfolio
The expected return on a portfolio is the weighted average of the returns of
individual assets, where each asset's weight is determined by its weight in the
portfolio.

The formula is:
E (Rp) = [WaX E (Ra)] + [WaX E (Ra)]
Where
E= is stands for expected
Rp= Return on the portfolio
Wa= Weight of asset n where n my stand for asset a, betc.
Ra= Return on asset n where n may stand for asset a, betc
The portfolio standard deviation (p) measure the risk associated with the
expected return of the portfolio.
The formula is p = wa2 2+ wa2 2 + 2wawbrab a b
The term rab represents the correlation between the returns of investments a
and b. The correlation coefficient, r, will always reduce the portfolio standard
deviation as long as it is less than +1.00.
Portfolio diversification:
Diversification occurs when different assets make up a portfolio.
The benefit of diversification is risk reduction; the extent of this benefit
depends upon how the returns of various assets behave over time. The
market rewards diversification. We can lower risk without sacrificing expected
return, and/or we can increase expected return without having to assume
more risk. Diversifying among different kinds of assets is called asset
allocation.
45
-
8/2/2019 Risk Portfolio Management
46/84
The diversification can either be vertical or horizontal.
In vertical diversification a portfolio can have scripts of different companies
within the same industry. In horizontal diversification one can have different
scripts chosen from different industries.
An important way to reduce the risk of investing is to diversify your
investments. Diversification is akin to "not putting all your eggs in one
basket."
For example: Ifportfolio only consisted of stocks of technology companies, it
would likely face a substantial loss in value if a major event adversely affected
the technology industry.
There are different ways to diversify a portfolio whose holdings are
concentrated in one industry. We can invest in the stocks of companies
belonging to other industry groups. We can allocate our portfolio among
different categories of stocks, such as growth, value, or income stocks. We
can include bonds and cash investments in our asset-allocation decisions. We
can also diversify by investing in foreign stocks and bonds.
Diversification requires us to invest in securities whose investment returns do
not move together. In other words, the investment returns have a low
correlation. The correlation coefficient is used to measure the degree to which
returns of two securities are related. As we increase the number of securities
in our portfolio, we reach a point where likely diversified as much as
reasonably possible. Diversification should neither be too much or too less. It
should be adequate according to the size of the portfolio.

The Efficient Frontier and Portfolio Diversification
The graph on the shows how volatility increases the risk of loss of principal,
and how this risk worsens as the time horizon shrinks. So all other things
being equal, volatility is minimized in the portfolio.
If we graph the return rates and standard deviations for a collection of
securities, and for all portfolios we can get by allocating among them.
Markowitz showed that we get a region bounded by an upward-sloping curve,
which he called the efficient frontier.
It's clear that for any given value of standard deviation, we would like to
choose a portfolio that gives you the greatest possible rate of return; so we
always want a portfolio that lies up along the efficient frontier, rather than
lower down, in the interior of the region. This is the first important property of
the efficient frontier: it's where the best portfolios are.
47
-
8/2/2019 Risk Portfolio Management
48/84
The second important property of the efficient frontier is that it's curved, not
straight.
If we take a 50/50 allocation between two securities, assuming that the year-
to-year performance of these two securities is not perfectly in sync -- that is,
assuming that the great years and the lousy years for Security 1 don't
correspond perfectly to the great years and lousy years for Security 2, but that
their cycles are at least a little off -- then the standard deviation of the 50/50
allocation will be less than the average of the standard deviations of the two
securities separately. Graphically, this stretches the possible allocations to
the leftof the straight line joining the two securities

THE FOUR PILLARS OF DIVERSIFICATION:
a. The yield provided by an investment in a portfolio of assets will be
closer to the Mean Yield than an investment in a single asset.
b. When the yields are independent - most yields will be concentrated
around the Mean.
c. When all yields react similarly - the portfolio's variance will equal the
variance of its underlying assets.
d. If the yields are dependent - the portfolio's variance will be equal to or
less than the lowest
Market portfolio:
The efficient frontier is a collection of portfolios, each one optimal for a given
amount of risk. A quantity known as the Sharpe ratio represents a measure of
the amount of additional return (above the risk-free rate) a portfolio provides
compared to the risk it carries. The portfolio on the efficient frontier with the
highest Sharpe Ratio is known as the market portfolio, or sometimes the
super-efficient portfolio.
This portfolio has the property that any combination of it and the risk-free
asset will produce a return that is above the efficient frontier - offering a larger
return for a given amount of risk than a portfolio of risky assets on the frontier
would.

PORTFOLIO PERFORMANCE EVALUATION:
A Portfolio manager evaluates his portfolio performance and identifies the
sources of strengths and weakness. The evaluation of the portfolio provides a
feed back about the performance to evolve better management strategy. Even
though evaluation of portfolio performance is considered to be the last stage
of investment process, it is a continuous process. There are number of
situations in which an evaluation becomes necessary and important.
Evaluation has to take into account:
Rate of returns, or excess return over risk free rate.
Level of risk both systematic (beta) and unsystematic and residual risks
through proper diversification.
Some of the models used to evaluate portfolio performance are:
Sharpes ratio
Treynors ratio
Jensens alpha

-
8/2/2019 Risk Portfolio Management
51/84
Sharpes ratio:
A ratio developed by Nobel Laureate William F. Sharpe to measure risk-
adjusted performance. It is calculated by subtracting the risk-free rate from the
rate of return for a portfolio and dividing the result by the standard deviation of
the portfolio returns.
The Sharpe ratio tells us whether the returns of a portfolio are due to smart
investment decisions or a result of excess risk. This measurement is very
useful because although one portfolio or fund can reap higher returns than its
peers, it is only a good investment if those higher returns do not come with too
much additional risk. The greater a portfolio's Sharpe ratio, the better its risk-
adjusted performance has been.
Treynors ratio:
The Treynor ratio is a measurement of the returns earned in excess of that
which could have been earned on a risk less investment.
The Treynor ratio is also called reward-to-volatility ratio. It relates excess
return over the risk-free rate to the additional risk taken; however systematic
risk instead of total risk is used. The higher the Treynor ratio, the better is the
performance under analysis.
51
http://en.wikipedia.org/wiki/Investmenthttp://en.wikipedia.org/wiki/Investment -
8/2/2019 Risk Portfolio Management
52/84
Treynors ratio = (Average Return of the Portfolio - Average Return of
the Risk-Free Rate) / Beta of the Portfolio
Like the Sharpe ratio, the Treynor ratio (T) does not quantify the value added,
if any, of active portfolio management. It is a ranking criterion only. A ranking
of portfolios based on the Treynor Ratio is only useful if the portfolios under
consideration are sub-portfolios of a broader, fully diversified portfolio. If this is
not the case, portfolios with identical systematic risk, but different total risk,
will be rated the same.
Jensens alpha:
An alternative method of ranking portfolio management is Jensen's alpha,
which quantifies the added return as the excess return above the security
market line in the capital asset pricing model. Jensen's alpha (or Jensen's
Performance Index) is used to determine the excess return of a stock, other
security, orportfolio over the security's required rate of return as determined
by the Capital Asset Pricing Model.
This model is used to adjust for the level of beta risk, so that riskier securities
are expected to have higher returns. The measure was first used in the
evaluation ofmutual fund managers by Michael Jensen in the 1970's.

in portfolio management, a number of brokers and investment consultants
some of whom are also professionally qualified have become portfolio
managers. They have managed the funds of clients on both discretionary and
non-discretionary basis.
The recent CBI probe into the operations of many market dealers has
revealed the unscrupulous practices by banks, dealers and brokers in their
portfolio operations. The SEBI has then imposed stricter rules, which included
their registration, a code of conduct and minimum infrastructure, experience
and expertise etc.
The guidelines of SEBI are in the direction of making portfolio management a
responsible professional service to be rendered by experts in the field.
PORTFOLIO ANALYSIS:
Portfolio analysis includes portfolio construction, selection of securities,
revision of portfolio evaluation and monitoring the performance of the portfolio.
All these are part of subject of portfolio management which is a dynamic
concept. Individual securities have risk-return characteristics of their own.
Portfolios, which are combinations of securities may or may not take on the
aggregate characteristics of their individuals parts.
Portfolio analysis considers the determination of future risk and return
in holding various blends of individual securities. As we know that expected
return from individual securities carries some degree of risk. Various groups of
securities when held together behave in a different manner and give interest

payments and dividends also, which are different to the analysis of individual
securities. A combination of securities held together will give a beneficial
result if they are grouped in a manner to secure higher return after taking into
consideration the risk element.
There are two approaches in construction of the portfolio of securities. They
are
Traditional approach
Modern approach
TRADITIONAL APPROACH:
Traditional approach was based on the fact that risk could be measured on
each individual security through the process of finding out the standard
deviation and that security should be chosen where the deviation was the
lowest. Traditional approach believes that the market is inefficient and the
fundamental analyst can take advantage for the situation. Traditional
approach is a comprehensive financial plan for the individual. It takes into
account the individual needs such as housing, life insurance and pension
plans.
Traditional approach basically deals with two major decisions. They are
a) Determining the objectives of the portfolio
b) Selection of securities to be included in the portfolio

MODERN APPROACH:
Modern approach theory was brought out by Markowitz and Sharpe. It is
the combination of securities to get the most efficient portfolio. Combination of
securities can be made in many ways. Markowitz developed the theory of
diversification through scientific reasoning and method. Modern portfolio
theory believes in the maximization of return through a combination of
securities. The modern approach discusses the relationship between different
securities and then draws inter-relationships of risks between them. Markowitz
gives more attention to the process of selecting the portfolio. It does not deal
with the individual needs.

P = a2*(Xa) 2 + b2*(Xb) 2 + 2rab*a*b*Xa*Xb
Where,
P = portfolio risk
Xa = proportion of investment in security A
Xb = proportion of investment in security B
R12 = correlation co-efficient between security 1 & 2
a = standard deviation of security 1
b = standard deviation of security 2
For three securities:
p =(a)2(Xa)2+(b)2(Xb)2+ (c)2(Xc)2+ 2(Xa)(Xb)(rab)(a)(b) +
