How are BAC 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 BAC butterfly priced from the end-of-day chain at a 30-day expiry (ATM IV 24.89%), the computed maximum profit is $193.37 per contract and the computed maximum loss is -$80.00 per contract. Live intraday quotes will differ as the chain moves through the trading session.

What is the breakeven for a BAC butterfly?

The breakeven for the BAC butterfly priced on this page is roughly $55.80 and $60.20 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 BAC market-implied 1-standard-deviation expected move is approximately 7.14%; if the move sits well outside the breakeven distance, the structure's risk-reward becomes correspondingly tighter.

Current BAC snapshot

As of June 29, 2026, spot at $57.97, ATM IV 24.89%, IV rank 27.02%, expected move 7.14%. The butterfly on BAC 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 32-day expiry.

Why this butterfly structure on BAC specifically: BAC IV at 24.89% is on the cheap side of its 1-year range, which favors premium-buying structures like a BAC butterfly, with a market-implied 1-standard-deviation move of approximately 7.14% (roughly $4.14 on the underlying). The 32-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated BAC expiries trade a higher absolute premium for lower per-day decay. Position sizing on BAC should anchor to the underlying notional of $57.97 per share and to the trader's directional view on BAC stock.

BAC butterfly setup

The BAC 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 BAC near $57.97, the first option leg uses a $55.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed BAC chain at a 32-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 BAC shares for the stock leg in covered calls and collars).

Action	Type	Strike / Basis	Premium (est)
Buy 1	Call	$55.00	$3.80
Sell 2	Call	$58.00	$1.83
Buy 1	Call	$61.00	$0.65

When traders use butterfly on BAC

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

BAC thesis for this butterfly

The market-implied 1-standard-deviation range for BAC extends from approximately $53.83 on the downside to $62.11 on the upside. A BAC long call butterfly is a pinning play: it pays maximum at the middle strike if BAC settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current BAC IV rank near 27.02% 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 BAC at 24.89%. As a Financial Services name, BAC options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to BAC-specific events.

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