Capital Asset Pricing Model (CAPM):
CAPM is the method of calculating the expected return on investment. The formula to calculate the expected return using the CAPM model is:
The required rate of return (RA) on stock A 1/2 return on stock B. The risk-free rate is 1/4 return on stock A. The market portfolio is RM.
Compute the beta of A (bA), using the equation as shown below:
Rearrange the above-mentioned equation to determine the beta of A as follows:
Hence, the beta of A (bA) is computed above.
Compute the beta of B (bB), using the equation as shown below:
Rearrange the above-mentioned equation to determine the beta of B as follows:
Hence, the beta of B (bB) is computed above.

- The market portfolio (M) has the expected rate of return E(rM) = 0.12. Security A is traded in the market. We know that E(rA) = 0.17 and βA = 1.5. (1) What is the rate of return of the risk-free asset (rf)? (2) Security B is also traded in the market. βB = 0.8. Then what is “fair” expected rate of return of security B according to the CAPM? (3) Security C is a third security traded in the market. βC = 0.6, and from the market price, investors calculate E(rC) = 0.1. Is C overpriced or underpriced? What is αC?arrow_forwardequals the slope of the security market line: one. beta. the market risk premium. the expected return on the market portfolio.arrow_forwardWhat is the Capital Asset Pricing Model (CAPM)?

- When we test CAPM using historical data, a classic test is to regress excess returns of stocks onto the stock betas, using the following regression specification across stocks: - Rp Rf =α+By+ε where Rup - Rf is the average excess return of a security or portfolio, ẞ is the estimated beta of the security or portfolio, & is the regression residual, and a (Alpha) and y (Gamma) are regression coefficients. Based on the regression, which of the following statements are true if CAPM is true? Select all two correct statements. The Alpha is zero The Alpha is positive The Gamma is positive The Gamma is zeroarrow_forwardAssume the CAPM holds and consider stock X, which has a return variance of 0.09 and a correlation of 0.75 with the market portfolio. The market portfolio's Sharpe ratio is 0.30 and the the risk-free rate is 5%. (a) What is Stock X's expected return? (b) What proportion of Stock X's return volatility (i.e. standard deviation) is priced by the market? Explain why this number is less than 1.arrow_forwardThe beta of a portfolio is: A.
