What is a butterfly on MPB?
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 MPB snapshot
As of May 15, 2026, spot at $31.15, ATM IV 41.50%, IV rank 15.39%, expected move 11.90%. The butterfly on MPB 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 MPB specifically: MPB IV at 41.50% is on the cheap side of its 1-year range, which favors premium-buying structures like a MPB butterfly, with a market-implied 1-standard-deviation move of approximately 11.90% (roughly $3.71 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 MPB expiries trade a higher absolute premium for lower per-day decay. Position sizing on MPB should anchor to the underlying notional of $31.15 per share and to the trader's directional view on MPB stock.
MPB butterfly setup
The MPB 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 MPB near $31.15, the first option leg uses a $29.59 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed MPB 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 MPB shares for the stock leg in covered calls and collars).

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

| Buy 1 | Call | $32.71 | N/A |

MPB thesis for this butterfly
The market-implied 1-standard-deviation range for MPB extends from approximately $27.44 on the downside to $34.86 on the upside. A MPB long call butterfly is a pinning play: it pays maximum at the middle strike if MPB settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current MPB IV rank near 15.39% 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 MPB at 41.50%. As a Financial Services name, MPB options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to MPB-specific events.
MPB 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. MPB positions also carry Financial Services sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move MPB alongside the broader basket even when MPB-specific fundamentals are unchanged. Always rebuild the position from current MPB chain quotes before placing a trade.
