- Assume that the CAPM holds. One stock has an expected return of 8% and a beta of 0.3. Another stock has an expected return of 14% and a beta of 1.5. What is the return-to-risk ratio that CAPM assumes equal across all individual stocks?arrow_forwardSuppose 0.3 is the correlation of returns between any two stocks in an equal-weighted portfolio containing N stocks. Suppose the volatility of any stock is 25%.

Rf= 2% and Rm = 12%. Using CAPM, what are the expected returns for each stock? Return of stock = Risk free rate + beta ( market rate of return - risk free rate of return) Return of Stock A = 2% + 1.20 (12% - 2%) = 2.12% Return of Stock B = 2% + 0.80 (12% - 2%) = 2.08% What is the expected return of an equally weighted portfolio of these two stocks? Weight of stock A = 0.50 Weight of Stock B = 0.50 Expected return = (Return of Stock A * weight of Stock A) + (Return of Stock B * weight of stock B) = (2.12 * 0.50) + (2.08*0.50) = 1.06 + 1.04 = 3% What is the beta of an equally weighted portfolio of these two stocks?
