Question: Yonan Corporation's stock had a required return of 11.50% last year, when the risk-free rate was 5.50% and the market risk premium was 4.75%. Now suppose there is a shift in investor risk aversion, and the market risk premium increases by 2%. The risk-free rate and Yonan's beta remain unchanged. What is Yonan's new required return? (Hint: First calculate the beta, then find the required return.)
