Capital Asset Pricing Model (CAPM)
Capital Asset Pricing Model implementation
AdvancedPosition Management
Overview
The Capital Asset Pricing Model (CAPM), originating in 1964, is an extremely relevant part of financial management that focuses on the relationship between risk and expected return.
CAPM examines the sensitivity of an asset's rate of return to systematic risk - the risk that affects the entire stock market and cannot be diversified away.
The model provides a framework for determining whether an investment is worth the risk by calculating the expected return based on the asset's systematic risk (beta).
