STXU snapshot

As of September 29, 2026, spot at $13.50, ATM IV 161.70%, expected move 46.36%. The butterfly on STXU 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 80-day expiry.

Why this butterfly structure on STXU specifically: IV rank is unavailable in the current snapshot, so regime-based timing for STXU is inferred from ATM IV at 161.70% alone, with a market-implied 1-standard-deviation move of approximately 46.36% (roughly $6.26 on the underlying). The 80-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated STXU expiries trade a higher absolute premium for lower per-day decay. Position sizing on STXU should anchor to the underlying notional of $13.50 per share and to the trader's directional view on STXU etf.

STXU butterfly setup

The STXU butterfly 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 STXU at $13.50 on that close, the first option leg uses a $13.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed STXU chain at a 80-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 STXU shares for the stock leg in covered calls and collars).

Buy 1	Call	$13.00	$4.05
Sell 2	Call	$13.00	$4.05
Buy 1	Call	$14.00	$3.73

When traders use butterfly on STXU

Butterflies on STXU are pinning bets - traders use them when they expect STXU to settle near a specific level at expiration (often the prior close, a round number, or the max-pain strike) and want defined-risk exposure to that outcome.

STXU thesis for this butterfly

The market-implied 1-standard-deviation range for STXU extends from approximately $7.24 on the downside to $19.76 on the upside. A STXU long call butterfly is a pinning play: it pays maximum at the middle strike if STXU settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. As a Financial Services name, STXU options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to STXU-specific events.

STXU butterfly positions are structurally neutral / pin (limited-risk, limited-reward); 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. STXU positions also carry Financial Services sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move STXU alongside the broader basket even when STXU-specific fundamentals are unchanged. Always rebuild the position from current STXU chain quotes before placing a trade.
