How are GPC 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 GPC butterfly priced from the end-of-day chain at a 30-day expiry (ATM IV 29.40%), the computed maximum profit is $441.97 per contract and the computed maximum loss is -$542.50 per contract. Live intraday quotes will differ as the chain moves through the trading session.

What is the breakeven for a GPC butterfly?

The breakeven for the GPC butterfly priced on this page is roughly $115.43 and $124.58 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 GPC market-implied 1-standard-deviation expected move is approximately 8.43%; if the move sits well outside the breakeven distance, the structure's risk-reward becomes correspondingly tighter.

How does current GPC implied volatility affect this butterfly?

The company’s operations are segmented into its Automotive Parts Group and Industrial Parts Group. The Automotive Parts Group supplies an extensive inventory of replacement components for a wide spectrum of vehicles, including hybrid and electric models, trucks, SUVs, buses, motorcycles, recreational and farm vehicles, small engines, marine equipment, and heavy-duty machinery, as well as various accessory and supply items. Its diverse clientele encompasses automotive repair facilities, service stations, fleet operators, vehicle dealerships (cars and trucks), leasing firms, bus and truck lines, large-scale retailers, farms, industrial enterprises, and individual consumers.

GPC (Genuine Parts Company) trades in the Consumer Cyclical sector, specifically Specialty Retail, with a market capitalization of approximately $16.14B, a trailing P/E of 265.73, a beta of 0.68 versus the broader market, a 52-week range of 90.78-151.57, average daily share volume of 1.8M, a public-listing history dating back to 1980, approximately 63K full-time employees. These structural characteristics shape how GPC stock options price implied volatility around earnings windows, capital events, and macro-driven sector rotations.

A beta of 0.68 indicates GPC has historically moved less than the broader market, dampening realized volatility and producing tighter expected-move bands per unit of dollar exposure. The trailing P/E of 265.73 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. GPC pays a dividend, which adjusts put-call parity and shifts the ex-dividend pricing across the listed chain.

What is a butterfly on GPC?

A long call butterfly buys one lower-strike call, sells two ATM calls, and buys one higher-strike call, paying a small net debit for a defined-risk position that maxes out if the underlying pins the middle strike at expiration.

Current GPC snapshot

As of June 30, 2026, spot at $118.06, ATM IV 29.40%, IV rank 48.15%, expected move 8.43%. The butterfly on GPC 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 GPC specifically: GPC IV at 29.40% 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 8.43% (roughly $9.95 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 GPC expiries trade a higher absolute premium for lower per-day decay. Position sizing on GPC should anchor to the underlying notional of $118.06 per share and to the trader's directional view on GPC stock.

GPC butterfly setup

The GPC 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 GPC near $118.06, the first option leg uses a $110.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed GPC 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 GPC shares for the stock leg in covered calls and collars).

Action	Type	Strike / Basis	Premium (est)
Buy 1	Call	$110.00	$9.00
Sell 2	Call	$120.00	$2.20
Buy 1	Call	$125.00	$0.83

When traders use butterfly on GPC

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

GPC thesis for this butterfly

The market-implied 1-standard-deviation range for GPC extends from approximately $108.11 on the downside to $128.01 on the upside. A GPC long call butterfly is a pinning play: it pays maximum at the middle strike if GPC settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current GPC IV rank near 48.15% is mid-range against its 1-year distribution, so the IV signal is neutral; the butterfly thesis on GPC should anchor more to the directional view and the expected-move geometry. As a Consumer Cyclical name, GPC options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to GPC-specific events.

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