Beta and required rate of return A stock has a required return of 16%; the risk-free rate is 6.5%; and the market risk premium is 6%. What is the stock's beta? Round your answer to two decimal places. If the market risk premium increased to 10%, what would happen to the stock's required rate of return? Assume that the risk-free rate and the beta remain unchanged. If the stock's beta is greater than 1.0, then the change in required rate...
