How are GNRC 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 GNRC butterfly priced from the end-of-day chain at a 30-day expiry (ATM IV 67.59%), the computed maximum profit is $1,297.41 per contract and the computed maximum loss is -$140.00 per contract. Live intraday quotes will differ as the chain moves through the trading session.

What is the breakeven for a GNRC butterfly?

The breakeven for the GNRC butterfly priced on this page is roughly $266.40 and $293.70 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 GNRC market-implied 1-standard-deviation expected move is approximately 19.38%; if the move sits well outside the breakeven distance, the structure's risk-reward becomes correspondingly tighter.

How does current GNRC implied volatility affect this butterfly?

GNRC ATM IV is at 67.59% with IV rank near 100.00%, 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 GNRC snapshot

As of June 29, 2026, spot at $280.78, ATM IV 67.59%, IV rank 100.00%, expected move 19.38%. The butterfly on GNRC 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 32-day expiry.

Why this butterfly structure on GNRC specifically: GNRC IV at 67.59% is rich versus its 1-year range, which makes a premium-buying GNRC butterfly relatively expensive in absolute-cost terms, with a market-implied 1-standard-deviation move of approximately 19.38% (roughly $54.41 on the underlying). The 32-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated GNRC expiries trade a higher absolute premium for lower per-day decay. Position sizing on GNRC should anchor to the underlying notional of $280.78 per share and to the trader's directional view on GNRC stock.

GNRC butterfly setup

The GNRC 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 GNRC near $280.78, the first option leg uses a $265.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed GNRC chain at a 32-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 GNRC shares for the stock leg in covered calls and collars).

Action	Type	Strike / Basis	Premium (est)
Buy 1	Call	$265.00	$32.85
Sell 2	Call	$280.00	$24.90
Buy 1	Call	$295.00	$18.35

When traders use butterfly on GNRC

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

GNRC thesis for this butterfly

The market-implied 1-standard-deviation range for GNRC extends from approximately $226.37 on the downside to $335.19 on the upside. A GNRC long call butterfly is a pinning play: it pays maximum at the middle strike if GNRC settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current GNRC IV rank near 100.00% 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 GNRC at 67.59%. As a Industrials name, GNRC options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to GNRC-specific events.

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