How are WAB 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 WAB butterfly priced from the end-of-day chain at a 30-day expiry (ATM IV 27.40%), the computed maximum profit is $1,071.91 per contract and the computed maximum loss is -$872.50 per contract. Live intraday quotes will differ as the chain moves through the trading session.

What is the breakeven for a WAB butterfly?

The breakeven for the WAB butterfly priced on this page is roughly $271.28 at expiration, derived from end-of-day chain premiums.

It serves publicly traded railroads; leasing companies; manufacturers of original equipment, including locomotives and freight cars; and utilities. The Transit segment manufactures and services components for new and existing passenger transit vehicles, such as regional trains, high speed trains, subway cars, light-rail vehicles, and buses; refurbishes subway cars; and provides heating, ventilation, and air conditioning equipment, as well as doors for buses and subways. This segment serves public transit authorities and municipalities, leasing companies, and manufacturers of subway cars and buses.

WAB (Westinghouse Air Brake Technologies Corporation) trades in the Industrials sector, specifically Railroads, with a market capitalization of approximately $44.93B, a trailing P/E of 37.20, a beta of 0.97 versus the broader market, a 52-week range of 184.26-275.84, average daily share volume of 964K, a public-listing history dating back to 1995, approximately 30K full-time employees. These structural characteristics shape how WAB stock options price implied volatility around earnings windows, capital events, and macro-driven sector rotations.

A beta of 0.97 places WAB roughly in line with broader market moves, so the strategy payoff and realized volatility track the index-equivalent baseline. The trailing P/E of 37.20 is on the rich side, which tends to correlate with higher earnings-window IV expansion as the market debates whether forward growth supports the multiple. WAB pays a dividend, which adjusts put-call parity and shifts the ex-dividend pricing across the listed chain.

What is a butterfly on WAB?

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 WAB snapshot

As of May 15, 2026, spot at $263.41, ATM IV 27.40%, IV rank 36.75%, expected move 7.86%. The butterfly on WAB 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 butterfly structure on WAB specifically: WAB IV at 27.40% 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 7.86% (roughly $20.69 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 WAB expiries trade a higher absolute premium for lower per-day decay. Position sizing on WAB should anchor to the underlying notional of $263.41 per share and to the trader's directional view on WAB stock.

WAB butterfly setup

The WAB 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 WAB near $263.41, the first option leg uses a $250.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed WAB 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 WAB shares for the stock leg in covered calls and collars).

Action	Type	Strike / Basis	Premium (est)
Buy 1	Call	$250.00	$17.35
Sell 2	Call	$260.00	$10.65
Buy 1	Call	$280.00	$2.68

When traders use butterfly on WAB

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

WAB thesis for this butterfly

The market-implied 1-standard-deviation range for WAB extends from approximately $242.72 on the downside to $284.10 on the upside. A WAB long call butterfly is a pinning play: it pays maximum at the middle strike if WAB settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current WAB IV rank near 36.75% is mid-range against its 1-year distribution, so the IV signal is neutral; the butterfly thesis on WAB should anchor more to the directional view and the expected-move geometry. As a Industrials name, WAB options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to WAB-specific events.

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