Bullish Case: PLXS at $252.36 has rebounded +5.8% weekly from $238.53, and the Helium density concentrates peak probability near $250 with a fat right shoulder toward $270-300 (density 0.0866 at $260, 0.069 at $270). Call volume runs 20% above puts, bullish risk is 21% higher across tenors, and the AI forecast is +3.57%. The historical return surface weights small-to-moderate positive returns, and mean reversion after the -11.9% 90-day drawdown supports a grind toward $260-270.

Bearish Case: The term structure remains backwardated with deep-OTM short-dated puts at 75-148% IV — thin liquidity and asymmetric tail pricing that preceded every prior dislocation. The Helium forecast's realized correlation is -0.3, historically a contrarian negative signal. Price sits below the 90-day $286.59 level, insider selling and margin pressure persist, and a SPY shock (SPY surface shows 35%+ IV on downside wings) would drag PLXS disproportionately.

Potential Outcomes:

1. Range reversion $245-265 (40%): mean reversion holds; falsified if $240 puts' IV (41.4%) compresses while price breaks $265.
2. Bull reclaim $270+ (25%): A&D contract wins or Oct guidance lift; watch 11/20 270C (40% IV, 474 volume, delta 0.38) as confirmation.
3. Drift lower $225-245 (20%): macro risk-off or catalyst fade; SPY weakness is the trigger.
4. Fast gap < $225 (10%): liquidity tail; deep-OTM put IV spike above 100% at short tenors is the falsifiable signal.
5. M&A/contract surprise (5%): +20-30% gap on announced deal or large award.

Calibration note: my range/reversion and skew-tail calls (July, August) tracked realized behavior best; upside break calls were repeatedly early.
