Market Risk Premium is a foundational concept in modern finance that quantifies the excess return an investor expects to earn when investing in the market portfolio compared to the risk-free rate. This premium compensates investors for taking on systematic risk that cannot be eliminated through diversification.
Key Components:
- Expected Market Return (Rm): The anticipated return from the overall market
- Risk-free Rate (Rf): The return on a zero-risk investment, typically government securities
- Risk Premium: The difference between market return and risk-free rate
