How are CSW 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 CSW butterfly priced from the end-of-day chain at a 30-day expiry (ATM IV 33.90%), the computed maximum profit is $758.50 per contract and the computed maximum loss is -$1,142.50 per contract. Live intraday quotes will differ as the chain moves through the trading session.

What is the breakeven for a CSW butterfly?

The breakeven for the CSW butterfly priced on this page is roughly $271.43 and $288.65 at expiration, derived from end-of-day chain premiums.

CSW (CSW Industrials, Inc.) trades in the Industrials sector, specifically Industrial - Machinery, with a market capitalization of approximately $4.61B, a trailing P/E of 42.01, a beta of 0.84 versus the broader market, a 52-week range of 230.45-337.023, average daily share volume of 135K, a public-listing history dating back to 2015, approximately 3K full-time employees.

A beta of 0.84 places CSW roughly in line with broader market moves, so the strategy payoff and realized volatility track the index-equivalent baseline. The trailing P/E of 42.01 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.

Current CSW snapshot

As of June 30, 2026, spot at $277.61, ATM IV 33.90%, IV rank 30.27%, expected move 9.72%. The butterfly on CSW 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 17-day expiry.

Why this butterfly structure on CSW specifically: CSW IV at 33.90% 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 9.72% (roughly $26.98 on the underlying). The 17-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated CSW expiries trade a higher absolute premium for lower per-day decay. Position sizing on CSW should anchor to the underlying notional of $277.61 per share and to the trader's directional view on CSW stock.

CSW butterfly setup

The CSW 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 CSW near $277.61, the first option leg uses a $260.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed CSW chain at a 17-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 CSW shares for the stock leg in covered calls and collars).

Action	Type	Strike / Basis	Premium (est)
Buy 1	Call	$260.00	$21.40
Sell 2	Call	$280.00	$7.50
Buy 1	Call	$290.00	$5.03

When traders use butterfly on CSW

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

CSW thesis for this butterfly

The market-implied 1-standard-deviation range for CSW extends from approximately $250.63 on the downside to $304.59 on the upside. A CSW long call butterfly is a pinning play: it pays maximum at the middle strike if CSW settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current CSW IV rank near 30.27% is mid-range against its 1-year distribution, so the IV signal is neutral; the butterfly thesis on CSW should anchor more to the directional view and the expected-move geometry. As a Industrials name, CSW options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to CSW-specific events.

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