Illustrative, not advice
- Crowded positioning may already reflect the move
- Counter-catalyst could neutralize the thesis before window closes
- MRK closes below pre-catalyst level on rising volume
- Catalyst narrative is officially walked back or contradicted
- Cross-asset confirmation (rates / FX / vol) reverses direction
- MRK price vs. pre-event level
- MRK volume vs. 20-day average
