How are EFX straddle max profit and max loss calculated?

Upside max profit is unbounded; downside max profit is bounded at the strike minus the combined call plus put debit (reached at zero). Max loss equals the combined debit times 100 (reached when the underlying pins to the strike). Two breakevens at strike plus debit and strike minus debit. For the EFX straddle priced from the end-of-day chain at a 30-day expiry (ATM IV 39.90%), the computed maximum profit is unbounded per contract and the computed maximum loss is -$1,525.45 per contract. Live intraday quotes will differ as the chain moves through the trading session.

What is the breakeven for a EFX straddle?

The breakeven for the EFX straddle priced on this page is roughly $144.45 and $175.55 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 EFX market-implied 1-standard-deviation expected move is approximately 11.44%; if the move sits well outside the breakeven distance, the structure's risk-reward becomes correspondingly tighter.

Current EFX snapshot

As of May 15, 2026, spot at $157.91, ATM IV 39.90%, IV rank 56.83%, expected move 11.44%. The straddle on EFX 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 straddle structure on EFX specifically: EFX IV at 39.90% 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 11.44% (roughly $18.06 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 EFX expiries trade a higher absolute premium for lower per-day decay. Position sizing on EFX should anchor to the underlying notional of $157.91 per share and to the trader's directional view on EFX stock.

EFX straddle setup

The EFX straddle below is built from the end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With EFX near $157.91, the first option leg uses a $160.00 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 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 EFX shares for the stock leg in covered calls and collars).

Action	Type	Strike / Basis	Premium (est)
Buy 1	Call	$160.00	$6.60
Buy 1	Put	$160.00	$8.95

When traders use straddle on EFX

Straddles on EFX are pure-volatility plays that profit from large moves in either direction; traders typically buy EFX straddles ahead of earnings, FDA decisions, or other catalysts where the realized move is expected to exceed the implied move priced into the chain.

EFX thesis for this straddle

The market-implied 1-standard-deviation range for EFX extends from approximately $139.85 on the downside to $175.97 on the upside. A EFX long straddle is a pure-volatility play: it profits when the underlying moves far enough from the strike in either direction to overcome the combined call plus put debit, regardless of direction. Current EFX IV rank near 56.83% is mid-range against its 1-year distribution, so the IV signal is neutral; the straddle 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 straddle positions are structurally neutral / high-volatility (long premium); 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.
