Bullish Case: PALL at $22.17 sits at the bottom of its mean-reverting range; calls traded 69% more volume than puts, and backwardation plus elevated short-dated IV (~43% on Dec 24-strike puts) signals physical tightness. Helium's density places the highest mode at $24 with a secondary bulge near $23, and market-implied density peaks at $23–24—both above spot—suggesting mean reversion toward $23–25 if OEM buying or Russian export friction materializes.

Bearish Case: PALL is down 80% year-over-year, -10.5% in a month, with backwardation signaling continued near-term stress. The IV surface shows fat deep-OTM wings (strikes 14–19 IVs 57–200%) implying crash-hedging demand. Helium's density retains a lower mode near $17–19, and EV substitution, a firm USD, and deteriorating auto demand could break the $21 floor toward $19–20.

Potential Outcomes:

1. 40% Mean reversion to $23–25 by Dec 18 — Helium/market density modes cluster there; falsified by a close below $21.
2. 25% Grind sideways $21.5–23 (backwardation persists, no catalyst).
3. 20% Breakdown to $19–20 on EV substitution or USD strength (IV wings price this tail).
4. 10% Squeeze to $26–28 on supply shock/OEM restock (call-heavy volume supports).
5. 5% Gap below $18 (macro vol shock; SPY downside IV elevated).
