How are EFX 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 EFX butterfly priced from the August 14, 2026 end-of-day chain at a 30-day expiry (ATM IV 36.80%), the computed maximum profit is $463.03 per contract and the computed maximum loss is -$470.00 per contract. Live intraday quotes will differ as the chain moves through the trading session.

What is the breakeven for a EFX butterfly?

The breakeven for the EFX butterfly priced on this page is roughly $185.30 at expiration, derived from the August 14, 2026 end-of-day chain's premiums. Breakeven is the underlying price at which the strategy's P&L crosses zero ignoring transaction costs and assignment risk. The EFX market-implied 1-standard-deviation expected move in the same options snapshot is approximately 10.55%; if the move sits well outside the breakeven distance, the structure's risk-reward becomes correspondingly tighter.

How does current EFX implied volatility affect this butterfly?

EFX ATM IV is at 36.80% with IV rank near 37.83%, 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.

EFX snapshot

As of August 14, 2026, spot at $182.07, ATM IV 36.80%, IV rank 37.83%, expected move 10.55%. The butterfly on EFX below is built from the August 14, 2026 end-of-day chain, with strikes snapped to listed contracts and premiums pulled from the bid/ask midpoint at a 35-day expiry.

Why this butterfly structure on EFX specifically: EFX IV at 36.80% 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 10.55% (roughly $19.21 on the underlying). The 35-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated EFX expiries trade a higher absolute premium for lower per-day decay. Position sizing on EFX should anchor to the underlying notional of $182.07 per share and to the trader's directional view on EFX stock.

EFX butterfly setup

The EFX butterfly below is built from the August 14, 2026 end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With EFX at $182.07 on that close, the first option leg uses a $175.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed EFX chain at a 35-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 EFX shares for the stock leg in covered calls and collars).

Action	Type	Strike / Basis	Premium (est)
Buy 1	Call	$175.00	$13.00
Sell 2	Call	$180.00	$9.05
Buy 1	Call	$190.00	$4.80

When traders use butterfly on EFX

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

EFX thesis for this butterfly

The market-implied 1-standard-deviation range for EFX extends from approximately $162.86 on the downside to $201.28 on the upside. A EFX long call butterfly is a pinning play: it pays maximum at the middle strike if EFX settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current EFX IV rank near 37.83% is mid-range against its 1-year distribution, so the IV signal is neutral; the butterfly thesis on EFX should anchor more to the directional view and the expected-move geometry. As a Industrials name, EFX options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to EFX-specific events.

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