How are PSMT 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 PSMT butterfly priced from the August 14, 2026 end-of-day chain at a 30-day expiry (ATM IV 30.60%), the computed maximum profit is $779.39 per contract and the computed maximum loss is -$200.00 per contract.

What is the breakeven for a PSMT butterfly?

The breakeven for the PSMT butterfly priced on this page is roughly $172.00 and $188.00 at expiration, derived from the August 14, 2026 end-of-day chain's premiums.

PSMT snapshot

As of August 14, 2026, spot at $178.89, ATM IV 30.60%, IV rank 19.48%, expected move 8.77%. The butterfly on PSMT below is built from the August 14, 2026 end-of-day chain, with strikes snapped to listed contracts and premiums pulled from the bid/ask midpoint at a 35-day expiry.

Why this butterfly structure on PSMT specifically: PSMT IV at 30.60% is on the cheap side of its 1-year range, which favors premium-buying structures like a PSMT butterfly, with a market-implied 1-standard-deviation move of approximately 8.77% (roughly $15.69 on the underlying). The 35-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated PSMT expiries trade a higher absolute premium for lower per-day decay. Position sizing on PSMT should anchor to the underlying notional of $178.89 per share and to the trader's directional view on PSMT stock.

PSMT butterfly setup

The PSMT butterfly below is built from the August 14, 2026 end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With PSMT at $178.89 on that close, the first option leg uses a $170.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed PSMT chain at a 35-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 PSMT shares for the stock leg in covered calls and collars).

Action	Type	Strike / Basis	Premium (est)
Buy 1	Call	$170.00	$12.00
Sell 2	Call	$180.00	$6.40
Buy 1	Call	$190.00	$2.80

When traders use butterfly on PSMT

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

PSMT thesis for this butterfly

The market-implied 1-standard-deviation range for PSMT extends from approximately $163.20 on the downside to $194.58 on the upside. A PSMT long call butterfly is a pinning play: it pays maximum at the middle strike if PSMT settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current PSMT IV rank near 19.48% sits in the lower third of its 1-year distribution, where IV often re-expands toward the mean; this favors premium-buying structures and disadvantages premium-selling structures on PSMT at 30.60%. As a Consumer Defensive name, PSMT options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to PSMT-specific events.

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