Lottery-Stock Avoidance
In plain terms
If a stock had a few wild up-days last month, retail piles in and overpays for it — so it tends to underperform next. We fade those lottery names.
How it works
High recent maximum daily returns predict underperformance (Bali-Cakici-Whitelaw 2011) — used as a fade signal: stay flat or short when the rolling 1- or 3-month max daily return is in the top 10-20% of own history. Two variants per lookback: flat_when_lottery (zero exposure during the lottery regime) and short_when_lottery (active short capturing the full underperformance).

Counterintuitive: high-idiosyncratic-vol stocks UNDERPERFORM. So short the high-IVOL names, long the steady ones.
