How are INSW 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 INSW butterfly priced from the end-of-day chain at a 30-day expiry (ATM IV 60.40%), the computed maximum profit is $367.44 per contract and the computed maximum loss is -$122.50 per contract. Live intraday quotes will differ as the chain moves through the trading session.

What is the breakeven for a INSW butterfly?

It operates in two segments, Crude Tankers and Product Carriers. As of December 31, 2021, the company owned and operated a fleet of 83 vessels, which include 12 chartered-in vessels, as well as had ownership interests in two floating storage and offloading service vessels.

INSW (International Seaways, Inc.) trades in the Energy sector, specifically Oil & Gas Midstream, with a market capitalization of approximately $4.22B, a trailing P/E of 7.73, a beta of -0.08 versus the broader market, a 52-week range of 35.6-92.66, average daily share volume of 612K, a public-listing history dating back to 2016, approximately 3K full-time employees. These structural characteristics shape how INSW stock options price implied volatility around earnings windows, capital events, and macro-driven sector rotations.

A beta of -0.08 indicates INSW 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 7.73 is on the value side, where IV often compresses outside event windows because forward growth expectations are already discounted into the share price. INSW pays a dividend, which adjusts put-call parity and shifts the ex-dividend pricing across the listed chain.

What is a butterfly on INSW?

Current INSW snapshot

As of May 15, 2026, spot at $84.47, ATM IV 60.40%, IV rank 61.65%, expected move 17.32%. The butterfly on INSW 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 INSW specifically: INSW IV at 60.40% 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 17.32% (roughly $14.63 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 INSW expiries trade a higher absolute premium for lower per-day decay. Position sizing on INSW should anchor to the underlying notional of $84.47 per share and to the trader's directional view on INSW stock.

INSW butterfly setup

The INSW 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 INSW near $84.47, the first option leg uses a $80.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed INSW 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 INSW shares for the stock leg in covered calls and collars).

Action	Type	Strike / Basis	Premium (est)
Buy 1	Call	$80.00	$7.05
Sell 2	Call	$85.00	$4.35
Buy 1	Call	$90.00	$2.88

When traders use butterfly on INSW

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

INSW thesis for this butterfly

The market-implied 1-standard-deviation range for INSW extends from approximately $69.84 on the downside to $99.10 on the upside. A INSW long call butterfly is a pinning play: it pays maximum at the middle strike if INSW settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current INSW IV rank near 61.65% is mid-range against its 1-year distribution, so the IV signal is neutral; the butterfly thesis on INSW should anchor more to the directional view and the expected-move geometry. As a Energy name, INSW options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to INSW-specific events.

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