SPAX snapshot
As of September 29, 2026, spot at $9.98, ATM IV 90.40%, expected move 25.92%. The bull call spread on SPAX below is built from the September 29, 2026 end-of-day chain, with strikes snapped to listed contracts and premiums pulled from the bid/ask midpoint at a 17-day expiry.
Why this bull call spread structure on SPAX specifically: IV rank is unavailable in the current snapshot, so regime-based timing for SPAX is inferred from ATM IV at 90.40% alone, with a market-implied 1-standard-deviation move of approximately 25.92% (roughly $2.59 on the underlying). The 17-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated SPAX expiries trade a higher absolute premium for lower per-day decay. Position sizing on SPAX should anchor to the underlying notional of $9.98 per share and to the trader's directional view on SPAX etf.
SPAX bull call spread setup
The SPAX bull call spread below is built from the September 29, 2026 end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With SPAX at $9.98 on that close, the first option leg uses a $10.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed SPAX chain at a 17-day expiry; the cross-strike IV skew is reflected directly in the per-leg values rather than approximated. Quantity sizing assumes one contract per option leg (or 100 SPAX shares for the stock leg in covered calls and collars).
| Action | Type | Strike / Basis | Premium (est) |

SPAX thesis for this bull call spread
The market-implied 1-standard-deviation range for SPAX extends from approximately $7.39 on the downside to $12.57 on the upside. A SPAX bull call spread caps both the risk and the reward of a bullish position; relative to an outright long call on SPAX, the spread reduces the cost basis but limits the maximum profit to the strike width minus net debit. As a Financial Services name, SPAX options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to SPAX-specific events.
SPAX bull call spread positions are structurally moderately bullish; the modeled P&L assumes European-style exercise at expiration and ignores early assignment, transaction costs, dividends paid before expiry on the stock leg (when present), and the bid-ask spread on the listed chain. SPAX positions also carry Financial Services sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move SPAX alongside the broader basket even when SPAX-specific fundamentals are unchanged. Long-premium structures like a bull call spread on SPAX are particularly exposed to IV-crush risk through scheduled events (earnings, FDA decisions, central-bank meetings) where IV typically contracts post-event regardless of the directional outcome. Always rebuild the position from current SPAX chain quotes before placing a trade.
