    Illustrative, not advice

    Risks
    • Crowded positioning may already reflect the move
    • Counter-catalyst could neutralize the thesis before window closes
    Invalidation
    • ASML closes above pre-catalyst level on rising volume
    • Catalyst narrative is officially walked back or contradicted
    • Cross-asset confirmation (rates / FX / vol) reverses direction
    Monitor
    • ASML price vs. pre-event level
    • ASML volume vs. 20-day average
