How are MGA butterfly max profit and max loss calculated?

Max profit equals the wing width minus net debit times 100 (reached when the underlying pins the middle strike); max loss equals the net debit times 100. Two breakevens at lower-wing plus debit and upper-wing minus debit. For the MGA butterfly priced from the end-of-day chain at a 30-day expiry (ATM IV 32.50%), the computed maximum profit is $212.22 per contract and the computed maximum loss is -$35.00 per contract. Live intraday quotes will differ as the chain moves through the trading session.

What is the breakeven for a MGA butterfly?

The breakeven for the MGA butterfly priced on this page is roughly $57.85 and $62.15 at expiration, derived from end-of-day chain premiums. Breakeven is the underlying price at which the strategy's P&L crosses zero ignoring transaction costs and assignment risk. The current MGA market-implied 1-standard-deviation expected move is approximately 9.32%; if the move sits well outside the breakeven distance, the structure's risk-reward becomes correspondingly tighter.

How does current MGA implied volatility affect this butterfly?

Current MGA snapshot

As of May 15, 2026, spot at $60.27, ATM IV 32.50%, IV rank 30.42%, expected move 9.32%. The butterfly on MGA 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 MGA specifically: MGA IV at 32.50% is mid-range versus its 1-year history, so strategy selection should anchor more to the directional thesis than to the IV regime, with a market-implied 1-standard-deviation move of approximately 9.32% (roughly $5.62 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 MGA expiries trade a higher absolute premium for lower per-day decay. Position sizing on MGA should anchor to the underlying notional of $60.27 per share and to the trader's directional view on MGA stock.

MGA butterfly setup

The MGA 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 MGA near $60.27, the first option leg uses a $57.50 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed MGA 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 MGA shares for the stock leg in covered calls and collars).

Action	Type	Strike / Basis	Premium (est)
Buy 1	Call	$57.50	$4.40
Sell 2	Call	$60.00	$2.88
Buy 1	Call	$62.50	$1.70

When traders use butterfly on MGA

Butterflies on MGA are pinning bets - traders use them when they expect MGA 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.

MGA thesis for this butterfly

The market-implied 1-standard-deviation range for MGA extends from approximately $54.65 on the downside to $65.89 on the upside. A MGA long call butterfly is a pinning play: it pays maximum at the middle strike if MGA settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current MGA IV rank near 30.42% is mid-range against its 1-year distribution, so the IV signal is neutral; the butterfly thesis on MGA should anchor more to the directional view and the expected-move geometry. As a Consumer Cyclical name, MGA options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to MGA-specific events.

MGA 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. MGA positions also carry Consumer Cyclical sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move MGA alongside the broader basket even when MGA-specific fundamentals are unchanged. Always rebuild the position from current MGA chain quotes before placing a trade.
