Current SRTY snapshot
As of May 15, 2026, spot at $27.89, ATM IV 69.50%, IV rank 14.51%, expected move 19.93%. The butterfly on SRTY below is built from the same end-of-day chain, with strikes snapped to listed contracts and premiums pulled from the bid/ask midpoint at a 34-day expiry.
Why this butterfly structure on SRTY specifically: SRTY IV at 69.50% is on the cheap side of its 1-year range, which favors premium-buying structures like a SRTY butterfly, with a market-implied 1-standard-deviation move of approximately 19.93% (roughly $5.56 on the underlying). The 34-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated SRTY expiries trade a higher absolute premium for lower per-day decay. Position sizing on SRTY should anchor to the underlying notional of $27.89 per share and to the trader's directional view on SRTY etf.
SRTY butterfly setup
The SRTY butterfly below is built from the end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With SRTY near $27.89, the first option leg uses a $26.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed SRTY chain at a 34-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 SRTY shares for the stock leg in covered calls and collars).

| Sell 2 | Call | $28.00 | $2.30 |
| Buy 1 | Call | $29.00 | $1.93 |

When traders use butterfly on SRTY
Butterflies on SRTY are pinning bets - traders use them when they expect SRTY 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.
SRTY thesis for this butterfly
The market-implied 1-standard-deviation range for SRTY extends from approximately $22.33 on the downside to $33.45 on the upside. A SRTY long call butterfly is a pinning play: it pays maximum at the middle strike if SRTY settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current SRTY IV rank near 14.51% sits in the lower third of its 1-year distribution, where IV often re-expands toward the mean; this favors premium-buying structures and disadvantages premium-selling structures on SRTY at 69.50%. As a Financial Services name, SRTY options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to SRTY-specific events.
SRTY 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. SRTY positions also carry Financial Services sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move SRTY alongside the broader basket even when SRTY-specific fundamentals are unchanged. Always rebuild the position from current SRTY chain quotes before placing a trade.
