Bullish Case: PLXS rebounded +8.4% in a week to $239.34 with call volume 91% above puts and bullish risk 13% higher across tenors—flows are leaning into recovery. Mean-reverting price action plus the Helium return surface's concentration at small positive returns supports a grind back toward $250–260. 11/20 240C/240P straddle activity (delta ~0.5, IV ~53%) suggests an event re-rating is possible if Q4 A&D execution lands.

Bearish Case: The stock is still -10.1% monthly and -4.8% quarterly, below the 90-day mean, and the term structure is backwardated—near-term IV (~53% at ATM, rising to 130%+ on wings) pricing event risk into late-November earnings. The Helium AI forecast (+1.64%) carries a -0.3 realized correlation, historically a contrarian warning. Deep-OTM put IV (220P at 56%) and thin ask-side liquidity signal asymmetric downside if guidance disappoints or SPY's fat put-skew (35%+ downside IV) shocks risk appetite.

Potential Outcomes:

1. Range reversion $235–255 (40%): Mean reversion holds post-rebound; falsified if 240P IV compresses while price breaks $245.
2. Bull reclaim $260–275 (20%): Clean earnings beat/A&D wins; confirmation via 11/20 270C delta lift above 0.25.
3. Drift lower $220–235 (25%): SPY weakness or catalyst fade; watch SPY surface's red downside wing widening.
4. Event gap < $215 (10%): Late-Nov guidance cut; falsifiable via short-dated put IV spike >100%.
5. Contract/M&A surprise +15–25% (5%): Large award announced pre-earnings.
