How are SA 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 SA butterfly priced from the end-of-day chain at a 30-day expiry (ATM IV 66.50%), the computed maximum profit is $112.17 per contract and the computed maximum loss is -$85.00 per contract. Live intraday quotes will differ as the chain moves through the trading session.

What is the breakeven for a SA butterfly?

The breakeven for the SA butterfly priced on this page is roughly $30.15 at expiration, derived from end-of-day chain premiums. Breakeven is the underlying price at which the strategy's P&L crosses zero ignoring transaction costs and assignment risk. The current SA market-implied 1-standard-deviation expected move is approximately 19.06%; if the move sits well outside the breakeven distance, the structure's risk-reward becomes correspondingly tighter.

How does current SA implied volatility affect this butterfly?

SA ATM IV is at 66.50% with IV rank near 51.85%, which is mid-range against its 1-year history. Strategy selection depends more on directional thesis and expected move than on a strong IV signal.

Current SA snapshot

As of May 15, 2026, spot at $29.41, ATM IV 66.50%, IV rank 51.85%, expected move 19.06%. The butterfly on SA 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 SA specifically: SA IV at 66.50% 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 19.06% (roughly $5.61 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 SA expiries trade a higher absolute premium for lower per-day decay. Position sizing on SA should anchor to the underlying notional of $29.41 per share and to the trader's directional view on SA stock.

SA butterfly setup

The SA 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 SA near $29.41, the first option leg uses a $28.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed SA 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 SA shares for the stock leg in covered calls and collars).

Action	Type	Strike / Basis	Premium (est)
Buy 1	Call	$28.00	$3.25
Sell 2	Call	$29.00	$2.65
Buy 1	Call	$31.00	$1.90

When traders use butterfly on SA

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

SA thesis for this butterfly

The market-implied 1-standard-deviation range for SA extends from approximately $23.80 on the downside to $35.02 on the upside. A SA long call butterfly is a pinning play: it pays maximum at the middle strike if SA settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current SA IV rank near 51.85% is mid-range against its 1-year distribution, so the IV signal is neutral; the butterfly thesis on SA should anchor more to the directional view and the expected-move geometry. As a Basic Materials name, SA options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to SA-specific events.

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