David knows that the beta of his portfolio is equal to 1, but he does not know the risk-free rate of return or the market risk premium. He also knows that the expected return on the market is 7.50 percent. What is the expected return on David’s portfolio?

7.5%

Explanation:

Since the beta of this portfolio is 1, it means that it is perfectly synced with the market rate of return. We are told that the market rate of return is 7.5%, so that means that the expected rate of return of the portfolio should also be equal to 7.5%.

Beta measures the volatility of the portfolio or the stocks in relation to the market. If the stock is less volatile, the beta will  be less than 1, if the stock is more volatile, the beta will be more than 1.
