Answer:
Consider the following calculations
Step-by-step explanation:
r=rf + B X (rm-rf)
rf=3%
B=0.84
rm-rf=7%
r=8.88%
So, given the market risk premium and beta, the return should be 8.9% by above equation
If he buys the stock
Total return=Dividend+ capital appreciation
4+(71-69)=6
Return%=8.70% (6/69)
Opprtunity cost is 8.9% as given the beta of stock and market risk premium, 8.9% should be the return.
But, the above stock is expected to give only 8.7% return (dividend and capital gain), so he should not invest, bad buy.
