What is a butterfly on SRTS?
A long call butterfly buys one lower-strike call, sells two ATM calls, and buys one higher-strike call, paying a small net debit for a defined-risk position that maxes out if the underlying pins the middle strike at expiration.
Current SRTS snapshot
As of May 15, 2026, spot at $3.63, ATM IV 108.90%, IV rank 23.96%, expected move 31.22%. The butterfly on SRTS 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 SRTS specifically: SRTS IV at 108.90% is on the cheap side of its 1-year range, which favors premium-buying structures like a SRTS butterfly, with a market-implied 1-standard-deviation move of approximately 31.22% (roughly $1.13 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 SRTS expiries trade a higher absolute premium for lower per-day decay. Position sizing on SRTS should anchor to the underlying notional of $3.63 per share and to the trader's directional view on SRTS stock.
SRTS butterfly setup
The SRTS 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 SRTS near $3.63, the first option leg uses a $3.45 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed SRTS 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 SRTS shares for the stock leg in covered calls and collars).

|---|---|---|---|
| Buy 1 | Call | $3.45 | N/A |
| Sell 2 | Call | $3.63 | N/A |
| Buy 1 | Call | $3.81 | N/A |

When traders use butterfly on SRTS
Butterflies on SRTS are pinning bets - traders use them when they expect SRTS 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.
SRTS thesis for this butterfly
The market-implied 1-standard-deviation range for SRTS extends from approximately $2.50 on the downside to $4.76 on the upside. A SRTS long call butterfly is a pinning play: it pays maximum at the middle strike if SRTS settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current SRTS IV rank near 23.96% 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 SRTS at 108.90%. As a Healthcare name, SRTS options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to SRTS-specific events.
SRTS 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. SRTS positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move SRTS alongside the broader basket even when SRTS-specific fundamentals are unchanged. Always rebuild the position from current SRTS chain quotes before placing a trade.
Frequently asked questions
- What is a butterfly on SRTS?

- How are SRTS butterfly max profit and max loss calculated?
