Final answer:
The expected return on a portfolio equally invested in a stock with a beta of 1.65 and an expected return of 11 percent and a risk-free asset earning 2.6 percent is 6.80 percent.
Step-by-step explanation:
To calculate the expected return on a portfolio that is equally invested in a stock with a beta of 1.65 and an expected return of 11 percent, and a risk-free asset that earns 2.6 percent, you would use the formula for a weighted average. Since the portfolio is equally invested in both assets, the weights are 0.5 for each. The calculation is as follows:
Expected Return on Portfolio = (Weight of Stock × Expected Return of Stock) + (Weight of Risk-free Asset × Expected Return of Risk-free Asset)
Expected Return on Portfolio = (0.5 × 11%) + (0.5 × 2.6%)
Expected Return on Portfolio = 5.5% + 1.3%
Expected Return on Portfolio = 6.80%
