Pre-earnings vol-sell

If realized move historically smaller than implied move + crush ≥50% — sell strangles or iron condors into earnings. Profit from vega bleed + crush.

Post-earnings drift play

Stocks with strong drift edge (winners drift ≥3% over next 3 days) — buy direction in initial reaction. Best for surprise beats with raised guidance.

Avoid: high realized history

Names where realized routinely >1.3× implied (NVDA, TSLA, NFLX historically). Vol-selling = blow-up risk. Better: buy expected-move strangles.
