An estimation of the CAPM and the security market line (purple) for the Dow Jones Industrial Average over 3 years for monthly data..

Here’s how CAPM is used, the formula for CAPM, its limitations and more. How CAPM works. ... RFR: Risk-free rate, typically the return on a Treasury security. Beta: ...

Prices here are determined with reference to macroeconomic variables–for the CAPM, the "overall market"; for the CCAPM, overall wealth– such that individual preferences are subsumed.
The Y-intercept of the SML is equal to the risk-free interest rate. The slope of the SML is equal to the market risk premium and reflects the risk return tradeoff at a given time: : = + [()] where: E(R i) is an expected return on security
In 2015, Fama and French extended the model, adding a further two factors — profitability and investment. Defined analogously to the HML factor, the profitability factor (RMW) is the difference between the returns of firms with robust (high) and weak (low) operating profitability; and the investment factor (CMA) is the difference between the returns of firms that invest conservatively and ...
