Bullish Case: AI storage demand is structural: Seagate's own Sept 14 survey shows 99% of IT leaders expect AI-driven storage growth with only 38% prepared, and 86% already seeing ROI. STX is up 17.4% in a week with mean-reverting history, bullish risk 11% above bearish across tenors, and Helium's +3.79% forecast. The term structure is flat (~64-70% Helium IV) — no near-term catastrophe is priced, favoring a grind toward $950-$1000.

Bearish Case: STX trades at 37.8x book after a ~775% two-year run and is still -10.3% from 90 days ago — parabolic valuation vulnerable to any memory-demand disappointment. Near-dated IVs hit 78-100% with the left tail (deep OTM puts at 96-120% IV) still rich, signaling hedging demand. Helium IV exceeds market IV by ~2% near-term, and Helium's forecast correlation to realized price is -0.2, weakening directional conviction.

Potential Outcomes:

1. 40%: Mean-reversion grind to $940-$1000; falsified by a weekly close under $880.
2. 28%: Range $880-$960 with IV decay; flat term structure and theta support short-vol.
3. 18%: Macro/SPY risk-off pulls STX to $820-$880; signalled by SPY left-tail IV lifting.
4. 10%: Catalyst rip >$1020 (HDD/AI capex headlines); call-side IV compresses.
5. 4%: Gap down <$840 on guidance/demand shock with IV >100%.
