How are SPGI 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 SPGI butterfly priced from the end-of-day chain at a 30-day expiry (ATM IV 34.95%), the computed maximum profit is $1,404.20 per contract and the computed maximum loss is -$535.00 per contract. Live intraday quotes will differ as the chain moves through the trading session.

What is the breakeven for a SPGI butterfly?

The breakeven for the SPGI butterfly priced on this page is roughly $395.35 and $424.65 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 SPGI market-implied 1-standard-deviation expected move is approximately 10.02%; if the move sits well outside the breakeven distance, the structure's risk-reward becomes correspondingly tighter.

How does current SPGI implied volatility affect this butterfly?

SPGI ATM IV is at 34.95% with IV rank near 73.95%, which is elevated relative to its 1-year range. Premium-selling structures (covered call, cash-secured put, iron condor) generally look more attractive when IV rank is high; premium-buying structures (long call, long put, debit spreads) are more expensive in that regime.

Current SPGI snapshot

As of June 29, 2026, spot at $408.55, ATM IV 34.95%, IV rank 73.95%, expected move 10.02%. The butterfly on SPGI 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 31-day expiry.

Why this butterfly structure on SPGI specifically: SPGI IV at 34.95% is rich versus its 1-year range, which makes a premium-buying SPGI butterfly relatively expensive in absolute-cost terms, with a market-implied 1-standard-deviation move of approximately 10.02% (roughly $40.94 on the underlying). The 31-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated SPGI expiries trade a higher absolute premium for lower per-day decay. Position sizing on SPGI should anchor to the underlying notional of $408.55 per share and to the trader's directional view on SPGI stock.

SPGI butterfly setup

The SPGI 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 SPGI near $408.55, the first option leg uses a $390.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed SPGI chain at a 31-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 SPGI shares for the stock leg in covered calls and collars).

Action	Type	Strike / Basis	Premium (est)
Buy 1	Call	$390.00	$27.30
Sell 2	Call	$410.00	$14.50
Buy 1	Call	$430.00	$7.05

When traders use butterfly on SPGI

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

SPGI thesis for this butterfly

The market-implied 1-standard-deviation range for SPGI extends from approximately $367.61 on the downside to $449.49 on the upside. A SPGI long call butterfly is a pinning play: it pays maximum at the middle strike if SPGI settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current SPGI IV rank near 73.95% sits in the upper third of its 1-year distribution, which historically reverts; this raises the bar for premium-buying structures and lowers it for premium-selling structures on SPGI at 34.95%. As a Financial Services name, SPGI options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to SPGI-specific events.

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