Assume that using the Security Market Line (SML) the required rate of return (RA) on stock A is
return on A. Return on market portfolio is denoted by RM. Find the ratio of beta of A (DA) to beta of B
(OB).
c)
Assume that the short-term risk-free rate is 3%, the market index S&P500 is expected to pay
returns of 15% with the standard deviation equal to 20%. Asset A pays on average 5%, has standard
deviation equal to 20% and is NOT correlated with the S&P500. Asset B pays on average 8%, also has
standard deviation equal to 20% and has correlation of 0.5 with the S&P500. Determine whether asset A
and B are overvalued or undervalued and explain why.
