Therefore, the SML continues in a straight line whether beta is positive or negative. The assets above the line are undervalued because for a given amount of risk (beta), they yield a higher return. Since we only sampled 50 of the data (via the Percent data edit box above), results should. The function should return a spectopo.m plot (below). This will pop up the popspectopo.m window (below). Why SML is a straight line?Īll the correctly priced securities are plotted on the SML. To plot the channel spectra and associated topographical maps, select Plot Channel spectra and maps. A negative-beta asset requires an unusually low expected return because when it is added to a well-diversified portfolio, it reduces the overall portfolio risk.

Interpret the CAPM, II When the covariance is negative, the beta is negative and the expected return is lower than the risk-free rate. Beta is used in the capital asset pricing model (CAPM), which describes the relationship between systematic risk and expected return for assets (usually stocks). Stocks that fall below the line are a poor risk, according to the SML theory.īeta is a measure of the volatility-or systematic risk-of a security or portfolio compared to the market as a whole.
