FCS 5510 Formula Sheet

*Note: The formulas I expect you to know are

colored in Red. They are either more conceptually

based, or are more commonly used than the

others. You need to have a passing familiarity with

the rest of the formulas, but I do not expect you to

memorize them. If you see these formulas you do

need to know in general what they are used for.

Note present value (PV) and future value (FV)

formulas are not here because I assume you

learned them somewhere else in one of the

prerequisite classes. You do need to understand

the setup of those formulas.

Unit 01

1. Return computation with cash purchase vs. margin purchase

• P0= the purchase price of the security

• P1= the selling price of the security

• M=margin

• n = number of shares

Return with cash purchase = ( P1 *n - P0 *n)/ (P0 * n)

Return with margin purchase = (P1 *n - P0 *n ) / (P0 * M *n)

If commission/transaction costs C are involved, then

Return with cash purchase = ( ( P1 *n - P0 *n) – C)/ (P0 * n)

Return with margin purchase =( (P1 *n - P0 *n ) –C) / (P0 * M *n)

Unit 02

1. Tax owed or saved

Tax owed or saved = Taxable amount * marginal tax rate

2. Expected Return

• E(r)= the expected return

• E(D)= the expected dividend or interest income

• P= the price of the asset

• E(g)=the expected growth in the value of the asset

3. Realized Return (Note this formula is pretty much the same as the expected

return except the numbers in expected returns are expected instead of real)

• r= the realized return

• D= the realized dividend or interest income

• P= the price of the asset

• g=the realized growth in the value of the asset

4. A Portfolio Standard Deviation (SDP) of Two Assets

• Notations:

– SA = Standard Deviation of asset A

– SB = Standard Deviation of asset B

– WA = Portfolio weight of asset A

– WB = Portfolio weight of asset B

– rAB=Correlation coefficient of assets A & B.

• Portfolio SDP of assets A and B is

5. Beta Coefficient

• Beta coefficient is an index of volatility of an asset relative to the volatility of

the market.

return on the market

18. Times – Interest Earned Ratio

Unit 05:

1. Expected Return

• E(d) = expected dividend

• P = price of the stock

• E (g) = expected growth

E(r) = (E(d)/P) + E(g)

2. Dividend Valuation Model – Assuming No Growth in Dividends Over Time

• V=Valuation

• D=Dividends

• k=Discount rate=Required return

2. Dividend Valuation Model-Dividend grows at rate g

• V=Valuation

• D0=Initial dividend (first year)

• k=Required return

• g=Dividends annual growth rate

3. Required Return (k) – in some other occasions the notation is rs

• rf = the risk free rate (i.e.Treasure Bill rate)

• rM = the return on the market

• β = the stock's beta

K=rf + (rM - rf)β
