C) Calculate the coefficients of variation for stock A and stock B;

D) If risk free rate is 2%, calculate the Sharpe Ratios for stock A and stock B.

E) What stock is a better investment opportunity?

2. If you have $10,000 to invest and you put $4,000 in stock A and $6,000 in stock B (the two stocks listed in Question 1), then what is the expected return rate of your portfolio (entire investment of $10,000)?.

3. The risk free rate is 2%. The expected return rate of the market portfolio is 8%. If stock C has a beta 1.5 and stock D has a beta 0.8, what are the expected return rates of stock C and stock D?

Explanation / Answer

1.A)

expected return rates E(r) for stock A=15%*0.3+0.6*5%-0.1*3%=7.2%

expected return rates E(r) for stock B=10%*0.3+0.6*8%-0.1*20%=5.8%

2.

the expected return rate of your portfolio=$4,000*7.2%+$6,000*5.8%=$636

3.

the expected return rates of stock C=2%+1.5(8%-2%)=2%+9%=11%

the expected return rates of stock C=2%+0.8(8%-2%)=2%+4.8%=6.8%
