What is the market risk premium if the expected return on a stock is 12% while its beta is 1.5? Assume the risk-free rate is 6% and the return on the market is 10%.
Explanation:
Using the Capital Asset Pricing Model (CAPM):
Formula: Expected return on stock = Risk-free rate + Beta × (Market return - Risk-free rate)
Given:
Calculation: [12% = 6% + 1.5 \times (10% - 6%)] [12% = 6% + 1.5 \times 4%] [12% = 6% + 6%] [12% = 12%] ✓
The market risk premium is defined as: [\text{Market Risk Premium} = \text{Market Return} - \text{Risk-free Rate}] [\text{Market Risk Premium} = 10% - 6% = 4%]
Therefore, the market risk premium is 4%, which corresponds to option B.
