Bullish Case: IMOS's record Q3 revenue (+37% YoY), AI/memory demand (51% of sales, Micron-linked), and capacity expansion remain intact despite the ~25% pullback from $72.68. Helium's density places peak likelihood near $55–60 (0.1791 at $55), nearly matching spot $54.39, and Helium's AI forecast is +2.25%. The IV surface shows a cooler ~70–75 ATM center versus 180–250 deep-put IV, implying market-priced drift up, not collapse; fat call strikes (12/18 65C IV 84%) suggest upside optionality is affordable.

Bearish Case: IMOS is -25.2% in one month, -5% over sixty days, still ~274% above ten-year levels, and the term structure remains in backwardation—a classic post-parabolic mean-reversion signature. Helium's density shows a fat left shoulder at $40–45 (0.147–0.164), heavier than the market's implied downside. Extreme deep-put IVs (151–205%) price gap/tail risk; October's record 28 Strait of Hormuz ship attacks keep macro tail risk elevated while SPY's calm ~10–20 IV surface won't cushion idiosyncratic Taiwan-semi weakness.

Potential Outcomes: 1. Range $50–58 (40%) — Helium/market PDFs peak at $55; falsified by break outside band.
2. Recovery $58–66 (22%) — AI/memory guidance; falsified if ATM IV (>70%) stays elevated without price lift.
3. Further slide $44–50 (20%) — momentum unwind; falsified if put skew flattens.
4. Beat + IV crush pop (12%) — falsified via raised guidance.
5. Macro/Hormuz tail < $44 (6%) — falsified if deep-put IV spikes >230%.
