How are TNK 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 TNK butterfly priced from the August 14, 2026 end-of-day chain at a 30-day expiry (ATM IV 38.80%), the computed maximum profit is $299.30 per contract and the computed maximum loss is -$185.00 per contract. Live intraday quotes will differ as the chain moves through the trading session.

What is the breakeven for a TNK butterfly?

The breakeven for the TNK butterfly priced on this page is roughly $80.85 and $87.15 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 TNK market-implied 1-standard-deviation expected move in the same options snapshot is approximately 11.12%; if the move sits well outside the breakeven distance, the structure's risk-reward becomes correspondingly tighter.

How does current TNK implied volatility affect this butterfly?

TNK ATM IV is at 38.80% with IV rank near 22.76%, 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.

TNK Butterfly Strategy

TNK (Teekay Tankers Ltd.), in the Industrials sector, (Marine Shipping industry), listed on NYSE.

Teekay Tankers Ltd. specializes in providing essential marine transportation solutions to the global oil industry, with its operations spanning Bermuda and international waters. The company's service offerings encompass both voyage and time charter arrangements, alongside specialized offshore ship-to-ship transfer operations for a diverse range of commodities. These primarily include crude oil and refined petroleum products, but also extend to liquid gases and various other specialized cargo. Beyond shipping, Teekay Tankers Ltd. further extends its expertise to include comprehensive commercial and technical management services for tankers. As of December 31, 2021, the company operated a substantial fleet, comprising 48 owned and leased double-hull oil tankers. This is supplemented by two Aframax tankers and a single LR2 tanker, all acquired via time charter agreements.

TNK (Teekay Tankers Ltd.) trades in the Industrials sector, specifically Marine Shipping, with a market capitalization of approximately $2.80B, a trailing P/E of 4.75, a beta of -0.25 versus the broader market, a 52-week range of 43.54-83.99, average daily share volume of 402K, a public-listing history dating back to 2007, approximately 2K full-time employees. These structural characteristics shape how TNK stock options price implied volatility around earnings windows, capital events, and macro-driven sector rotations.

A beta of -0.25 indicates TNK 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 4.75 is on the value side, where IV often compresses outside event windows because forward growth expectations are already discounted into the share price. TNK pays a dividend, which adjusts put-call parity and shifts the ex-dividend pricing across the listed chain.

What is a butterfly on TNK?

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.

TNK snapshot

As of August 14, 2026, spot at $85.44, ATM IV 38.80%, IV rank 22.76%, expected move 11.12%. The butterfly on TNK 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 7-day expiry.

Why this butterfly structure on TNK specifically: TNK IV at 38.80% is on the cheap side of its 1-year range, which favors premium-buying structures like a TNK butterfly, with a market-implied 1-standard-deviation move of approximately 11.12% (roughly $9.50 on the underlying). The 7-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated TNK expiries trade a higher absolute premium for lower per-day decay. Position sizing on TNK should anchor to the underlying notional of $85.44 per share and to the trader's directional view on TNK stock.

TNK butterfly setup

The TNK 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 TNK at $85.44 on that close, the first option leg uses a $79.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed TNK chain at a 7-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 TNK shares for the stock leg in covered calls and collars).

Action	Type	Strike / Basis	Premium (est)
Buy 1	Call	$79.00	$6.55
Sell 2	Call	$84.00	$2.65
Buy 1	Call	$89.00	$0.60

When traders use butterfly on TNK

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

TNK thesis for this butterfly

The market-implied 1-standard-deviation range for TNK extends from approximately $75.94 on the downside to $94.94 on the upside. A TNK long call butterfly is a pinning play: it pays maximum at the middle strike if TNK settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current TNK IV rank near 22.76% 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 TNK at 38.80%. As a Industrials name, TNK options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to TNK-specific events.

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