The Capital Asset Pricing Model (CAPM) is a foundational framework in finance for determining the expected return of an asset based on its systematic risk, or beta. It posits that an asset’s return should compensate investors for both the time value of money (risk-free rate) and the non-diversifiable risk associated with the overall market. The model’s core principle suggests that higher systematic risk necessitates a higher expected return to attract investment.
Assumption
The traditional CAPM relies on several key assumptions, including efficient markets, rational investors, and normally distributed asset returns. These assumptions are often challenged in the context of cryptocurrency markets, where volatility is high, returns exhibit fat tails (leptokurtosis), and market participants may not always act rationally. The model’s reliance on a single market factor (beta) struggles to capture the complex, multi-factor risk landscape of digital assets.
Application
While direct application of CAPM to crypto assets is problematic due to market microstructure differences, its underlying logic informs risk management and portfolio construction in derivatives trading. Quantitative analysts adapt CAPM principles by incorporating additional risk factors, such as liquidity risk and specific protocol risk, to better estimate the cost of capital for crypto-related investments and derivatives pricing.
