BETA COEFFICIENT Given the following information, determine the beta coefficient for Stock J that is consistent with equilibrium: r-12.5%; rRF 8-8 4.5% rM-10.5%. 8-9 REQUIRED RATE OF RETURN Stock R has a beta of 1.5, Stock S has a beta of 0.75, the req ured return on an average stock is 13%, and the risk-free rate of return is 7%. By how much does the required return on the riskier stock exceed the required retum on the less risky stock
