Definition of Market Risk Premium (MRP)
The Market Risk Premium (MRP) is the difference between the expected return on a market portfolio and the risk-free rate. It serves as a vital concept in finance, providing a quantitative measure of the extra return investors expect for taking on additional risk compared to investing in risk-free assets, such as government bonds.
Quick Reference: MRP vs ERP
Here’s a brief comparison of Market Risk Premium (MRP) and Equity Risk Premium (ERP):
| Feature | Market Risk Premium (MRP) | Equity Risk Premium (ERP) |
|---|---|---|
| Scope | Measures risk across the entire market | Focuses solely on the stock market |
| Calculation | Calculated as the expected return on the market portfolio minus the risk-free rate | Similarly calculated, but only considers equity returns |
| Risk Consideration | Incorporates various asset classes | Limited to stocks and equity investments |
| Usage | Integral to CAPM model and asset pricing | Often higher than MRP, reflecting unique stock risks |
| Slope of SML | Equal to the slope of the Security Market Line (SML) | Not directly represented by the SML |
Example Calculation
If the expected return on the market portfolio is 8% and the risk-free rate is 3%, the MRP would be calculated as:
\[ \text{MRP} = \text{Expected Market Return} - \text{Risk-Free Rate} = 8% - 3% = 5% \]
This means investors require an additional 5% return for taking on the risks associated with the market.
