How are BYD 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 BYD butterfly priced from the end-of-day chain at a 30-day expiry (ATM IV 26.90%), the computed maximum profit is $258.78 per contract and the computed maximum loss is -$212.50 per contract. Live intraday quotes will differ as the chain moves through the trading session.

What is the breakeven for a BYD butterfly?

The breakeven for the BYD butterfly priced on this page is roughly $77.13 at expiration, derived from end-of-day chain premiums.

BYD Butterfly Strategy

BYD (Boyd Gaming Corporation), in the Consumer Cyclical sector, (Gambling, Resorts & Casinos industry), listed on NYSE.

Boyd Gaming Corporation, together with its subsidiaries, operates as a multi-jurisdictional gaming company. It operates through three segments: Las Vegas Locals, Downtown Las Vegas, and Midwest & South. As of December 31, 2021, the company operated 28 gaming entertainment properties located in Nevada, Illinois, Indiana, Iowa, Kansas, Louisiana, Mississippi, Missouri, Ohio, and Pennsylvania. It also engages in owning and operating a travel agency. The company was founded in 1975 and is headquartered in Las Vegas, Nevada.

BYD (Boyd Gaming Corporation) trades in the Consumer Cyclical sector, specifically Gambling, Resorts & Casinos, with a market capitalization of approximately $5.99B, a trailing P/E of 3.37, a beta of 1.12 versus the broader market, a 52-week range of 72.01-89.96, average daily share volume of 959K, a public-listing history dating back to 1993, approximately 16K full-time employees. These structural characteristics shape how BYD stock options price implied volatility around earnings windows, capital events, and macro-driven sector rotations.

A beta of 1.12 places BYD roughly in line with broader market moves, so the strategy payoff and realized volatility track the index-equivalent baseline. The trailing P/E of 3.37 is on the value side, where IV often compresses outside event windows because forward growth expectations are already discounted into the share price. BYD pays a dividend, which adjusts put-call parity and shifts the ex-dividend pricing across the listed chain.

What is a butterfly on BYD?

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 BYD snapshot

As of May 15, 2026, spot at $79.09, ATM IV 26.90%, IV rank 35.78%, expected move 7.71%. The butterfly on BYD 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 BYD specifically: BYD IV at 26.90% 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 7.71% (roughly $6.10 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 BYD expiries trade a higher absolute premium for lower per-day decay. Position sizing on BYD should anchor to the underlying notional of $79.09 per share and to the trader's directional view on BYD stock.

BYD butterfly setup

The BYD 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 BYD near $79.09, the first option leg uses a $75.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed BYD 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 BYD shares for the stock leg in covered calls and collars).

Action	Type	Strike / Basis	Premium (est)
Buy 1	Call	$75.00	$5.45
Sell 2	Call	$80.00	$2.28
Buy 1	Call	$82.50	$1.23

When traders use butterfly on BYD

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

BYD thesis for this butterfly

The market-implied 1-standard-deviation range for BYD extends from approximately $72.99 on the downside to $85.19 on the upside. A BYD long call butterfly is a pinning play: it pays maximum at the middle strike if BYD settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current BYD IV rank near 35.78% is mid-range against its 1-year distribution, so the IV signal is neutral; the butterfly thesis on BYD should anchor more to the directional view and the expected-move geometry. As a Consumer Cyclical name, BYD options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to BYD-specific events.

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