Scope: these are forward returns vs the S&P among names still covered at each horizon's end, within the curated universe — not a survivorship-clean whole-market backtest. Names later dropped from coverage are counted as attrition (not hidden), and single-session moves beyond ±300% are treated as split/data artifacts and excluded.
