How are ATRO 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 ATRO butterfly priced from the August 14, 2026 end-of-day chain at a 30-day expiry (ATM IV 59.40%), the computed maximum profit is $471.45 per contract and the computed maximum loss is -$20.00 per contract. Live intraday quotes will differ as the chain moves through the trading session.

What is the breakeven for a ATRO butterfly?

The breakeven for the ATRO butterfly priced on this page is roughly $90.15 and $100.07 at expiration, derived from the August 14, 2026 end-of-day chain's premiums. Breakeven is the underlying price at which the strategy's P&L crosses zero ignoring transaction costs and assignment risk. The ATRO market-implied 1-standard-deviation expected move in the same options snapshot is approximately 17.03%; if the move sits well outside the breakeven distance, the structure's risk-reward becomes correspondingly tighter.

How does current ATRO implied volatility affect this butterfly?

ATRO ATM IV is at 59.40% with IV rank near 20.75%, which is on the low end of its 1-year range. Premium-buying structures (long call, long put, debit spreads) are relatively cheap in this regime; premium-selling structures collect less credit per unit risk.

ATRO Butterfly Strategy

ATRO (Astronics Corporation), in the Industrials sector, (Aerospace & Defense industry), listed on NASDAQ.

Astronics Corporation, through its subsidiaries, designs and manufactures products for the aerospace, defense, and electronics industries in the United States, rest of North America, Asia, Europe, South America, and internationally. It operates in two segments, Aerospace and Test Systems. The Aerospace segment offers lighting and safety systems, electrical power generation systems, distribution and seat motions systems, aircraft structures, avionics products, systems certification, and other products. This segment serves airframe manufacturers (OEM) that build aircraft for the commercial transport, military, and general aviation markets; suppliers to OEMs; and aircraft operators, such as airlines; suppliers to the aircraft operators; and branches of the U.S. Department of Defense. The Test Systems segment designs, develops, manufactures, and maintains automated test systems that support the aerospace and defense, communications, and mass transit industries, as well as training and simulation devices for commercial and military applications.

ATRO (Astronics Corporation) trades in the Industrials sector, specifically Aerospace & Defense, with a market capitalization of approximately $3.59B, a trailing P/E of 54.97, a beta of 1.20 versus the broader market, a 52-week range of 26.71189-94.46, average daily share volume of 690K, a public-listing history dating back to 1980, approximately 3K full-time employees. These structural characteristics shape how ATRO stock options price implied volatility around earnings windows, capital events, and macro-driven sector rotations.

A beta of 1.20 places ATRO roughly in line with broader market moves, so the strategy payoff and realized volatility track the index-equivalent baseline. The trailing P/E of 54.97 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. ATRO pays a dividend, which adjusts put-call parity and shifts the ex-dividend pricing across the listed chain.

What is a butterfly on ATRO?

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.

ATRO snapshot

As of August 14, 2026, spot at $93.50, ATM IV 59.40%, IV rank 20.75%, expected move 17.03%. The butterfly on ATRO 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 126-day expiry.

Why this butterfly structure on ATRO specifically: ATRO IV at 59.40% is on the cheap side of its 1-year range, which favors premium-buying structures like a ATRO butterfly, with a market-implied 1-standard-deviation move of approximately 17.03% (roughly $15.92 on the underlying). The 126-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated ATRO expiries trade a higher absolute premium for lower per-day decay. Position sizing on ATRO should anchor to the underlying notional of $93.50 per share and to the trader's directional view on ATRO stock.

ATRO butterfly setup

The ATRO 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 ATRO at $93.50 on that close, the first option leg uses a $90.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed ATRO chain at a 126-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 ATRO shares for the stock leg in covered calls and collars).

Action	Type	Strike / Basis	Premium (est)
Buy 1	Call	$90.00	$16.05
Sell 2	Call	$95.00	$13.75
Buy 1	Call	$100.00	$11.65

When traders use butterfly on ATRO

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

ATRO thesis for this butterfly

The market-implied 1-standard-deviation range for ATRO extends from approximately $77.58 on the downside to $109.42 on the upside. A ATRO long call butterfly is a pinning play: it pays maximum at the middle strike if ATRO settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current ATRO IV rank near 20.75% 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 ATRO at 59.40%. As a Industrials name, ATRO options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to ATRO-specific events.

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