What is a butterfly on MISL?
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 MISL snapshot
As of May 15, 2026, spot at $44.54, ATM IV 30.80%, IV rank 17.33%, expected move 8.83%. The butterfly on MISL 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 MISL specifically: MISL IV at 30.80% is on the cheap side of its 1-year range, which favors premium-buying structures like a MISL butterfly, with a market-implied 1-standard-deviation move of approximately 8.83% (roughly $3.93 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 MISL expiries trade a higher absolute premium for lower per-day decay. Position sizing on MISL should anchor to the underlying notional of $44.54 per share and to the trader's directional view on MISL etf.
MISL butterfly setup
The MISL 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 MISL near $44.54, the first option leg uses a $42.31 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed MISL 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 MISL shares for the stock leg in covered calls and collars).

|---|---|---|---|

| Sell 2 | Call | $44.54 | N/A |
| Buy 1 | Call | $46.77 | N/A |

When traders use butterfly on MISL
Butterflies on MISL are pinning bets - traders use them when they expect MISL 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.
MISL thesis for this butterfly
The market-implied 1-standard-deviation range for MISL extends from approximately $40.61 on the downside to $48.47 on the upside. A MISL long call butterfly is a pinning play: it pays maximum at the middle strike if MISL settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current MISL IV rank near 17.33% 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 MISL at 30.80%. As a Financial Services name, MISL options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to MISL-specific events.
MISL 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. MISL positions also carry Financial Services sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move MISL alongside the broader basket even when MISL-specific fundamentals are unchanged. Always rebuild the position from current MISL chain quotes before placing a trade.
