How are EW 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 EW butterfly priced from the end-of-day chain at a 30-day expiry (ATM IV 26.60%), the computed maximum profit is $376.61 per contract and the computed maximum loss is -$112.50 per contract. Live intraday quotes will differ as the chain moves through the trading session.

What is the breakeven for a EW butterfly?

The breakeven for the EW butterfly priced on this page is roughly $86.13 and $93.88 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 EW market-implied 1-standard-deviation expected move is approximately 7.63%; if the move sits well outside the breakeven distance, the structure's risk-reward becomes correspondingly tighter.

EW ATM IV is at 26.60% with IV rank near 21.52%, which is on the low end of its 1-year range. Premium-buying structures (long call, long put, debit spreads) are relatively cheap in this regime; premium-selling structures collect less credit per unit risk.

What is a butterfly on EW?

Current EW snapshot

As of June 30, 2026, spot at $90.34, ATM IV 26.60%, IV rank 21.52%, expected move 7.63%. The butterfly on EW 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 52-day expiry.

Why this butterfly structure on EW specifically: EW IV at 26.60% is on the cheap side of its 1-year range, which favors premium-buying structures like a EW butterfly, with a market-implied 1-standard-deviation move of approximately 7.63% (roughly $6.89 on the underlying). The 52-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated EW expiries trade a higher absolute premium for lower per-day decay. Position sizing on EW should anchor to the underlying notional of $90.34 per share and to the trader's directional view on EW stock.

EW butterfly setup

The EW 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 EW near $90.34, the first option leg uses a $85.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed EW chain at a 52-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 EW shares for the stock leg in covered calls and collars).

Action	Type	Strike / Basis	Premium (est)
Buy 1	Call	$85.00	$8.10
Sell 2	Call	$90.00	$4.85
Buy 1	Call	$95.00	$2.73

When traders use butterfly on EW

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

EW thesis for this butterfly

The market-implied 1-standard-deviation range for EW extends from approximately $83.45 on the downside to $97.23 on the upside. A EW long call butterfly is a pinning play: it pays maximum at the middle strike if EW settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current EW IV rank near 21.52% 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 EW at 26.60%. As a Healthcare name, EW options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to EW-specific events.

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