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
Signal weights (both directions): Follow-Through 25% · Volume 20% · Price Trajectory 20% · Drawdown 15% · Fundamentals 20%
Classification requires ≥3 days of data; full confidence requires all 5 trading days. ≥60% directional score = decisive classification, otherwise Uncertain.
