Answer:
11.11%
Explanation:
The full question with table is attached.
We need the rate of return formula using Capital Asset Pricing Model (CAPM). The formula is:
[tex]R=R_f+\beta(R_m-R_f)[/tex]
Where
R is rate of return (what we need)
[tex]R_f[/tex] is risk-free return rate (5% = 0.05)
[tex]R_m[/tex] is the market rate of return (11% = 0.11)
To get [tex]\beta[/tex], we take the weighted average of the portfolio.
Weight of Stock A = 1,075,000/3,000,000 = 0.3583
Weight of Stock B = 675,000/3,000,000 = 0.225
Weight of Stock C = 750,000/3,000,000 = 0.25
Weight of Stock D = 500,000/3,000,000 = 0.1667
Portfolio Beta = (0.3583*1.2) + (0.225*0.50) + (0.25*1.40) + (0.1667*0.75) = 1.02
Now, we calculate rate of return using CAPM formula:
[tex]R=R_f+\beta(R_m-R_f)\\R=0.05+1.02(0.11-0.05)\\R=0.1112[/tex]
That is 11.12%, or from answer choice, it is 11.11%
