Bullish Case: BNS at $93.29 sits just below the Helium density peak (92.5–95, density 0.15–0.16) after a flat-to-grinding-higher tape. Helium's term-structure band (9.5–14.6% short-dated) prices far less vol than the market's 24.6%, implying left-tail premium should decay. Call flow runs 41% ahead of puts, the Scotia Global Intelligence wealth launch supports fee-income growth, and Q4 results due ~Dec 1 could push the 97.5–100 call cluster into play.

Bearish Case: Backwardation persists and market IV (24.6% near-term, rising to 25.2% in December) exceeds Helium's own band ceiling near earnings, signaling hedging demand into the Dec 18 expiry. Helium assigns far more mass above 100 than the market (0.06 vs 0.037) and market mass at 90–92.5 (0.154) is anchored just below spot — a December earnings or Canadian macro miss would hit BNS idiosyncratically given its 44.6% one-year run is extended.

Potential Outcomes:

1. 40% — Grind to 95–99 by Dec 19; IV compresses toward low-20s. Falsify: 3 closes <91.
2. 25% — Range 91–95 into January; Helium peak density holds. Falsify: ATM IV >3 pts higher without price gain.
3. 20% — Earnings-driven pullback to 86–90; Dec 90P IV (27.3%) re-rates. Falsify: holds >95 post-Dec 1.
4. 10% — Breakout >100 on credit/ROE beat; June 110C demand (19.3% IV) confirms.
5. 5% — Risk-off shock <85; falsified by tight Canadian bank spreads.
