Post-Gap Validation
A validation & avoid-list tool: tracks whether post-earnings gaps hold over 5-day price action. For gap-ups it distinguishes pump-and-dumps from genuine reratings; for gap-downs it separates reversals (dip-buys) from continued selloffs (avoids) — so you know which names to stay away from.

Forward Returns by Classification
Empirical proof the classifier works — for gap-downs, a negative 5d return confirms the AVOID read held. Averages hidden until enough completed trackers exist. (min 5).

How It Works
Gap Ups
🚫 Pump & Dump
- • Gap fills >70% within 5 days
- • Volume decays >60% (no follow-through)
- • Lower highs pattern (distribution)
- • Max drawdown >8% from gap close
✅ Genuine Rerating
- • Gap holds (<20% fill)
- • Volume sustained (<30% decay)
- • Higher highs, peak close day 4-5
- • Strong EPS beat or guidance raise
Gap Downs
✅ Reversal (DIP-BUY)
- • Recovered >70% of the down-gap
- • Selling volume decayed (panic exhausted)
- • Higher lows held above the capitulation low
- • Minimal further downside (<2%)
🚫 Selloff (AVOID)
- • Recovery <20% — stayed down
- • Sustained volume (continued distribution)
- • Peak close day 1, lower lows after
- • EPS miss or lowered guidance supporting the de-rating

Classification requires ≥3 days of data; full confidence requires all 5 trading days. ≥60% directional score = decisive classification, otherwise Uncertain.
