Bullish Case: GKOS at $168.115 grinds higher (+4% week, +7% 90d) with bullish risk 34% above bearish across tenors and Helium's PDF mass concentrated 155–175 (peak ~165–170 density 0.134). The term structure's Nov-21 IV peak (66.3%) prices the Oct-28 earnings catalyst; a Q3 beat would crush that premium and support a retest of the 60-day high near $185. A September call spread targeting $180 shows institutional upside interest.

Bearish Case: Put volume ran 424% above calls despite a 34% bullish-risk skew—hedging into Oct-28 earnings signals fragility. GKOS is -8.9% off its 60-day high with a 4.5x book multiple and a 102% one-year run already discounting perfection. Nov-21 IV at 66%+ and elevated downside put IV (Nov 145P at 71%) mean any Epioara/iDose launch or margin stumble could drop price into the 145–155 Helium tail region.

Potential Outcomes:

1. 38% — Beat + positive iDose trajectory: close >$175 by Nov-21; Nov ATM IV crushes to ~50%. Marker: hold >$165 pre-print.
2. 34% — In-line/chop: $155–175 range through December; term structure stays flat (Helium IV 53→63). Marker: Nov IV stays 60–68.
3. 22% — Disappointment: lose $160, Helium PDF's $135–150 tail activates (densities 0.05–0.09); Jan-16 IV rises above 58. Marker: Nov 160P volume expands.
4. 6% — Crash tail <$130 (deep-put IV structure); SPY risk-off impulse. Marker: 145P IV >75%.
