Downside beta
In investing, downside beta measures how a stock's returns move in relation to the market's returns only during periods when the market underperforms a specified target level, usually the risk-free rate or zero. Downside beta was developed by Hogan and Warren (1974) and later by Bawa and Lindenberg (1977). They extended CAPM to account for investor preferences toward downside risk rather than total variance — leading to the Downside-CAPM (D-CAPM).
