Q4
1.With a risk-free rate of 2.4% and a market risk-premium of 8.6%, a stock's expected rate of return is 10.7%. The following year, the market-risk premium decreases by 1% but the stock's beta and the risk-free rate remain the same. What will be the expected rate of return on the stock for that year? Answer as a percent return to the nearest hundredth of a percent as in xx.xx without entering a percent symbol. For negative returns include a negative sign.
2.In your two-stock portfolio, you invest $25 in stock A and $75 in stock B. If the beta of stock A is 0.97 and the beta of stock B is 0.74, your portfolio beta will be: Input your answer two places to the right of the decimal point as in x.xx
1) Risk free rate = 2.4% ; Market Risk premium = 8.6% ; Required rate of return = 10.7%
Firstly we need to calculate beta of the stock, the formula is as follows
required rate return = risk free rate + beta * market risk premium
10.7% = 2.4% + beta * 8.6%
10.7% - 2.4% = beta * 8.6%
beta = 8.3% / 8.6%
beta = 0.965
Now in the folowing year the Market Risk premium falls by 1% , risk free rate & beta remain same
So the expected rate of return comes out to be
= risk free rate + beta * market risk premium
= 2.4% + 0.965 * 7.6%
= 2.4% + 7.33%
= 9.73 %
So, the required rate of return comes out to be 9.73.
2) Investment in Stock A = $ 25 ; Investment in Stock B = $ 75
Beta of Stock A = 0.97 ; Beta of Stock B = 0.74
Total Investment = $ 100
Weightage of A = Investment in A / Total Investment
= 25 / 100 = 25%
Weightage of B = Investment in B / Total Investment
= 75 / 100 = 75%
Beta of Portfolio = Weighted Beta of Stock A + Weighted Beta of Stock B
Weighted Beta of Stock A = Beta of Stock * Weightage of Stock
= 0.97 * 25%
= 0.2424
Weighted Beta of Stock B = Beta of Stock * Weightage of Stock
= 0.74 * 75%
= 0.555
Beta of Portfolio = 0.2424 + 0.555
= 0.797 or 0.80
So beta of the portfolio is 0.80.
