12-Month Downside Risk
Definition phase
Downside risk is implemented as a downside beta. The signal keeps only the dates where the market is weak and measures how strongly each stock covaries with the market on those downside observations.
The economic intuition is that investors dislike assets that deliver their worst relative payoffs precisely when aggregate wealth and risk tolerance are already under pressure. That makes downside beta a bad-state risk characteristic rather than just another version of ordinary market beta.
Inside the finance research stack, the representative implementation sorts the Russell 1000 cross-section on downside beta and compares the high-downside-beta names against the low-downside-beta names in a market-neutral spread.
