Bullish Case: ASML raised 2026 guidance three times (35-38% revenue growth, 56% gross margin), posted a record $13B quarter, and demand still outstrips EUV supply. At $1,662.85 after a 22% drawdown from highs, the term structure shows steep backwardation (67% Nov 7 vs ~42% mid-2027) implying near-term fear is overpriced and should decay. Bullish risk runs 10% above bearish; if AI-capex fears settle and the stock reclaims $1,700, mean reversion toward $1,800+ is plausible.

Bearish Case: The AI trade is cracking: SOXX fell 10.2% in a week, CoreWeave's debt stress and Anthropic valuation cuts signal AI financing fragility. ASML trades at 24.4x book, puts outtraded calls by 77%, Helium's forecast correlation is -0.3, and market PDF mass sits at $1,000-1,390 — far below spot. A MATCH Act or China DUV escalation, or continued neocloud deleveraging, could extend the derating toward $1,300-1,450.

Potential Outcomes:

1. 28% — Continued derating, -8-15% in 4-8 weeks: put-led flow (77% put volume) and SPY downside-wing vol >40 persist; falsified if ASML reclaims $1,700 with IV collapsing below ~50.
2. 27% — Stabilization grind, ±5%: backwardated IV decays into mid-tenors (~39-42% Jan-Sep 2027); mean-reverting tape holds $1,530-1,590 support.
3. 22% — Vol crush rebound, +6-12%: Nov 7's 67% IV collapses post-event; earnings/guidance momentum reasserts; falsified if term structure stays backwardated.
4. 15% — Export-policy shock, -15-25%: MATCH Act passage or Beijing retaliation (Sindlhauser precedent) breaks $1,500.
5. 8% — Broad AI risk-off tail, -25%+: SPY surface red wing steepens further; ASML correlated drawdown.
