Security characteristic line

Security characteristic line (SCL) is a regression line, plotting performance of a particular security or portfolio against that of the market portfolio at every point in time. The SCL is plotted on a graph where the Y-axis is the excess return on a security over the risk-free return and the X-axis is the excess return of the market in general. The slope of the SCL is the security's beta, and the intercept is its alpha.

Formula

${\displaystyle \mathrm {SCL} :R_{i,t}-R_{f}=\alpha _{i}+\beta _{i}\,(R_{M,t}-R_{f})+\epsilon _{i,t}}$

where:

?_i is called the asset's alpha (abnormal return)

?_i(R_M,t - R_f) is a nondiversifiable or systematic risk

?_i,t is the non-systematic or diversifiable, non-market or idiosyncratic risk

R_M,t is a market risk

R_f is a risk-free rate
