a. Use a calculator with a linear regression function (or a spreadsheet) to determine
Stock ABC™s beta coef¬cient, or else plot these data points on a scatter diagram,
draw in the regression line, and then estimate the value of the beta coef¬cient
“by eye.”
b. Determine the arithmetic average rates of return for Stock ABC and the NYSE
over the period given. Calculate the standard deviations of returns for both
Stock ABC and the NYSE.
c. Assuming (1) that the situation during Years 1 to 7 is expected to hold true in
the future (that is, rABC “ABC; “M rM; and both ABC and bABC in the future
ˆ ˆ
r r
will equal their past values), and (2) that Stock ABC is in equilibrium (that is, it
plots on the SML), what is the implied risk-free rate?
d. Plot the Security Market Line.
e. Suppose you hold a large, well-diversi¬ed portfolio and are considering adding
to the portfolio either Stock ABC or another stock, Stock Y, that has the same
beta as Stock ABC but a higher standard deviation of returns. Stocks ABC and
ˆ ˆ
Y have the same expected returns; that is rABC rY 10.6%. Which stock
should you choose?
(28-17) The beta coef¬cient of an asset can be expressed as a function of the asset™s corre-
SML and CML lation with the market, its standard deviation, and the market™s standard deviation:

i,M i

a. Substitute this expression for beta into the Security Market Line (SML),
Equation 28-16. This results in an alternative form of the SML.
b. Compare your answer to part a with the Capital Market Line (CML), Equation
