We are measuring this pattern on survivorship-free data (delisted names included). Numbers appear here once the study completes.
Win% = share of occurrences with a positive forward return. Avg win / avg loss show the reward-to-risk, which matters as much as the hit rate — a high win rate with a bad reward/risk still loses.
