Bullish Case: DECK's forward curve moves from backwardated (~77–93% front IV) into a low, flat ~38–45% regime by December–2027, so the front-end fear premium is expiring. Helium's probability density peaks tightly at $85–86 with tails thin below $80, calls out-traded puts by 31%, fundamentals remain solid (FY27 Q1 sales +6%, Hoka +8%, forward P/E ~10.6), and the stock sits near a 52-week low with S&P +13% YTD — supportive of premium decay and a drift back toward $90+ if the sportswear narrative stabilizes.

Bearish Case: The Nike warning (China -26%, weak medium-term sportswear outlook, discounting, layoffs) is a direct demand-channel read for Hoka/UGG, and Williams Trading just cut its DECK target on valuation. Market IV (~93% front) exceeds Helium (~77%), backwardation signals near-term event risk, the market density is fatter in the $80–84 zone than Helium's, and DECK is -46.6% over two years with put strikes 85–86 still showing ~95% IV — downside hedging demand persists.

Potential Outcomes:

1. Range/gradual recovery $84–$92 (45%) — Helium density peaks at $85–86; call>put volume +31%; term structure normalizes. Falsified if spot sustains <$82 with rising IV.
2. Renewed weakness $78–$84 (30%) — Nike contagion, Williams PT cut, backwardated front end; market density fatter below $84 than Helium. Falsified by reclaiming $90 on falling IV.
3. Rally >$92 (15%) — short-covering or sector bottom calls (Motley Fool-style narrative) after IV crushes post-10/23 expiry.
4. Breakdown <$78 (10%) — macro/sector shock; SPY downside surface shows deep left-tail vol (35%+ IV at long tenors) that could spill over.

Oracle: spot <$82 with expanding front IV → bearish; spot >$88 with IV compressing toward ~60% → bullish.
