Risk and Return
Sarah is a financial analyst of a portfolio consisting of the stocks shown below.
The risk free rate is 3% and the market risk premium is 8%.
Stock H, Investment $2mil, Beta 1.4
Stock I, Investment $3mil, Beta 1.0
Stock J, Investment $5mil, Beta -0.2
Compute beta and expected return of portfolio.
Solutions
Expert Solution
Investment in Stock H = $2 mil
Investment in Stock I = $3 mil
Investment in Stock J = $5 mil
Total investment = 2+3+5 = $10 mil
Weight of stock H in the portfolio = wH = Investment in H/Total investment = 2/10 = 0.2
Weight of stock I in the portfolio = wI = Investment in I/Total investment = 3/10 = 0.3
Weight of stock J in the portfolio = wJ = Investment in J/Total investment = 5/10 = 0.5
Beta of stock H = βH = 1.4
Beta of stock I = βI = 1
Beta of stock J = βJ = -0.2
Beta of the portfolio can be calculated using the formula:
Beta of the portfolio = βP = wH*βH+wI*βI+wJ*βJ = 0.2*1.4 + 0.3*1 + 0.5*(-0.2) = 0.48
Now, we can use the CAPM equation to calculate the expected return on this portfolio
Expected return on the portfolio = E[RP] = RF+βP*MRP
where RF= Risk-free rate = 3%, βP = beta of the portfolio = 0.48, MRP = Market risk premium = 8%
Expected return of portfolio = E[RP] = 3%+(0.48*8%) = 3%+3.84% = 6.84%
Answer
Beta = 0.48
Expected return of portfolio = 6.84%

Portfolio expected return and risk
A collection of financial assets and securities is referred to
as a portfolio. Most individuals and institutions invest in a
portfolio, making portfolio risk analysis an integral part of
finance. Just like standalone assets and securities, portfolios are
also exposed to risk. Portfolio risk refers to the possibility that
an investment portfolio will not generate the expected rate of
return.
Analyzing portfolio risk and return involves the understanding
of expected returns from a portfolio.
