You have been managing a $5 million portfolio that has a beta of 1.15 and a required rate of return of 8.025%. The current risk-free rate is 4%. Assume that you receive another $500,000. If you invest the money in a stock with a beta of 0.95, what will be the required return on your $5.5 million portfolio? Do not round intermediate calculations. Round your answer to two decimal places.
Rf = Risk free rate = 4%
Beta = 1.15
Required return = 8.025%
Market Risk Premium = (Requied return - Risk free rate) / Beta
= (8.025% - 4%) / 1.15
= 4.025% / 1.15
= 3.5%
WA = Weight of Portfolio = $5,000,000 / $5,500,000 = 0.9090909
WB = Weight of new stock = $500,000 / $5,500,000 = 0.0909090
BA = Beta of Portfolio = 1.15
BB = Beta of new stock = 0.95
New Beta with stock = [WA * BA] + {WB * BB]
= [0.9090909 * 1.15] + [0.0909090 * 0.95]
= 1.04545454 + 0.08636355
= 1.13181809
Required return on $5.5 million portfolio = Rf + (New beta * Market Risk premium)
= 4% + (1.13181809 * 3.5%)
= 4% + 3.96136332%
= 7.96136332%
Therefore, Required return on $5.5 million portfolio is 7.96%
