How are EME 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 EME butterfly priced from the end-of-day chain at a 30-day expiry (ATM IV 39.50%), the computed maximum profit is $3,125.86 per contract and the computed maximum loss is -$745.00 per contract. Live intraday quotes will differ as the chain moves through the trading session.

What is the breakeven for a EME butterfly?

The breakeven for the EME butterfly priced on this page is roughly $797.43 and $862.55 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 EME market-implied 1-standard-deviation expected move is approximately 11.32%; if the move sits well outside the breakeven distance, the structure's risk-reward becomes correspondingly tighter.

How does current EME implied volatility affect this butterfly?

EME ATM IV is at 39.50% with IV rank near 43.33%, which is mid-range against its 1-year history. Strategy selection depends more on directional thesis and expected move than on a strong IV signal.

What is a butterfly on EME?

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 EME snapshot

As of June 30, 2026, spot at $827.13, ATM IV 39.50%, IV rank 43.33%, expected move 11.32%. The butterfly on EME 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 17-day expiry.

Why this butterfly structure on EME specifically: EME IV at 39.50% 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 11.32% (roughly $93.67 on the underlying). The 17-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated EME expiries trade a higher absolute premium for lower per-day decay. Position sizing on EME should anchor to the underlying notional of $827.13 per share and to the trader's directional view on EME stock.

EME butterfly setup

The EME 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 EME near $827.13, the first option leg uses a $790.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed EME chain at a 17-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 EME shares for the stock leg in covered calls and collars).

Action	Type	Strike / Basis	Premium (est)
Buy 1	Call	$790.00	$52.05
Sell 2	Call	$830.00	$28.25
Buy 1	Call	$870.00	$11.90

When traders use butterfly on EME

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

EME thesis for this butterfly

The market-implied 1-standard-deviation range for EME extends from approximately $733.46 on the downside to $920.80 on the upside. A EME long call butterfly is a pinning play: it pays maximum at the middle strike if EME settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current EME IV rank near 43.33% is mid-range against its 1-year distribution, so the IV signal is neutral; the butterfly thesis on EME should anchor more to the directional view and the expected-move geometry. As a Industrials name, EME options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to EME-specific events.

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