Bullish Case: COHR has cratered 44% in 60 days to $169.76, pricing near-worst-case AI de-rating. Calls now out-trade puts by 36% and bullish risk exceeds bearish by 4%—a sharp reversal from July–August put-heavy skew. Heavy call buying in Nov 13/20 strikes (170–210 at 145–285% IV) suggests speculators expect an oversold snapback; the term structure's extreme backwardation (181% one-week IV decaying to ~85% by spring) implies near-term event risk resolves quickly, and the Helium PDF shows dense probability mass at 170–182.5 with a fat tail to the upside.

Bearish Case: The -44% collapse reflects a genuine AI-capex de-grossing: SOX broke below its 200-day, hedge funds turned underweight AI, and optics peers (LITE -18%, CIEN -11%) fell together—COHR's drop is systematic, not idiosyncraatic noise. 7.6x book remains demanding at a cyclical top. Extreme backwardation means the market expects further near-term event risk (midterm de-grossing, macro risk-off); the market PDF shows material mass down at 105–150. Broken momentum plus $150–160 psychological support leaves room for another leg lower.

Potential Outcomes:

1. 35% — Oversold rebound to $180–200: Call-heavy flow (36% call volume lead), 180% one-week IV crush, and capitulation-level drop (-44%/60d) favor mean reversion. Falsifier: close below $150.
2. 30% — Continued de-grossing to $130–150: SOX below 200-day, hedge-fund AI underweighting, midterm de-risking persist. Falsifier: reclaim of $185.
3. 20% — Range $155–180 dead chop: IV decays faster than price; Helium PDF density concentrates here. Falsifier: break of either band.
4. 10% — Crash below $130: AI demand disappointment (Anthropic ARR miss, capex cuts) triggers second leg down.
5. 5% — V-shaped recovery >$200: Confirmed hyperscaler orders/guidance reversal.
