Final answer:
The beta of a stock with an expected return of 10.2%, a risk-free rate of 3.9%, and a market risk premium of 7.2% is 0.875.
Step-by-step explanation:
The student has asked a question related to the calculation of the beta of a stock, using the Capital Asset Pricing Model (CAPM). The CAPM formula is given by:
Expected Return = Risk-Free Rate + (Beta * Market Risk Premium)
Given the expected return of 10.2%, a risk-free rate of 3.9%, and a market risk premium of 7.2%, we can rearrange the CAPM formula to solve for Beta:
Beta = (Expected Return - Risk-Free Rate) / Market Risk Premium
Beta = (10.2% - 3.9%) / 7.2%
Beta = 6.3% / 7.2%
Beta = 0.875
Therefore, the beta of the stock must be 0.875.
