How are SWBI 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 SWBI butterfly priced from the end-of-day chain at a 30-day expiry (ATM IV 53.20%), the computed maximum profit is $47.50 per contract and the computed maximum loss is -$52.50 per contract. Live intraday quotes will differ as the chain moves through the trading session.

SWBI (Smith & Wesson Brands, Inc.) trades in the Industrials sector, specifically Aerospace & Defense, with a market capitalization of approximately $651.4M, a trailing P/E of 54.18, a beta of 0.93 versus the broader market, a 52-week range of 7.73-15.79, average daily share volume of 578K, a public-listing history dating back to 1999, approximately 2K full-time employees.

Current SWBI snapshot

As of May 15, 2026, spot at $15.41, ATM IV 53.20%, IV rank 44.36%, expected move 15.25%. The butterfly on SWBI 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 SWBI specifically: SWBI IV at 53.20% 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 15.25% (roughly $2.35 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 SWBI expiries trade a higher absolute premium for lower per-day decay. Position sizing on SWBI should anchor to the underlying notional of $15.41 per share and to the trader's directional view on SWBI stock.

SWBI butterfly setup

The SWBI 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 SWBI near $15.41, the first option leg uses a $15.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed SWBI 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 SWBI shares for the stock leg in covered calls and collars).

Action	Type	Strike / Basis	Premium (est)
Buy 1	Call	$15.00	$1.20
Sell 2	Call	$15.00	$1.20
Buy 1	Call	$16.00	$0.73

When traders use butterfly on SWBI

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

SWBI thesis for this butterfly

The market-implied 1-standard-deviation range for SWBI extends from approximately $13.06 on the downside to $17.76 on the upside. A SWBI long call butterfly is a pinning play: it pays maximum at the middle strike if SWBI settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current SWBI IV rank near 44.36% is mid-range against its 1-year distribution, so the IV signal is neutral; the butterfly thesis on SWBI should anchor more to the directional view and the expected-move geometry. As a Industrials name, SWBI options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to SWBI-specific events.

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