GASS Butterfly Strategy
GASS (StealthGas Inc.), in the Industrials sector, (Marine Shipping industry), listed on NASDAQ.
StealthGas Inc., together with its subsidiaries, provides seaborne transportation services to liquefied petroleum gas (LPG) producers and users internationally. It also provides crude oil and natural gas. The company's carriers carry various petroleum gas products in liquefied form, including propane, butane, butadiene, isopropane, propylene, and vinyl chloride monomer; and refined petroleum products, such as gasoline, diesel, fuel oil, and jet fuel, as well as edible oils and chemicals. As of December 31, 2021, it had a fleet of 44 LPG carriers with a total capacity of 389,426 cubic meters; three medium range product carriers with a total capacity of 140,000 deadweight tons (dwt); and one Aframax crude oil tanker with a total capacity of 115,804 dwt. StealthGas Inc. was incorporated in 2004 and is based in Athens, Greece.
GASS (StealthGas Inc.) trades in the Industrials sector, specifically Marine Shipping, with a market capitalization of approximately $375.2M, a trailing P/E of 6.01, a beta of 0.25 versus the broader market, a 52-week range of 5.22-10.52, average daily share volume of 168K, a public-listing history dating back to 2005, approximately 602 full-time employees. These structural characteristics shape how GASS stock options price implied volatility around earnings windows, capital events, and macro-driven sector rotations.
A beta of 0.25 indicates GASS 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 6.01 is on the value side, where IV often compresses outside event windows because forward growth expectations are already discounted into the share price.
What is a butterfly on GASS?
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 GASS snapshot
As of May 15, 2026, spot at $10.09, ATM IV 49.60%, IV rank 7.93%, expected move 14.22%. The butterfly on GASS 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 GASS specifically: GASS IV at 49.60% is on the cheap side of its 1-year range, which favors premium-buying structures like a GASS butterfly, with a market-implied 1-standard-deviation move of approximately 14.22% (roughly $1.43 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 GASS expiries trade a higher absolute premium for lower per-day decay. Position sizing on GASS should anchor to the underlying notional of $10.09 per share and to the trader's directional view on GASS stock.
GASS butterfly setup
The GASS 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 GASS near $10.09, the first option leg uses a $9.59 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed GASS 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 GASS shares for the stock leg in covered calls and collars).

|---|---|---|---|
| Buy 1 | Call | $9.59 | N/A |
| Sell 2 | Call | $10.09 | N/A |
| Buy 1 | Call | $10.59 | N/A |

When traders use butterfly on GASS
Butterflies on GASS are pinning bets - traders use them when they expect GASS 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.
GASS thesis for this butterfly
The market-implied 1-standard-deviation range for GASS extends from approximately $8.66 on the downside to $11.52 on the upside. A GASS long call butterfly is a pinning play: it pays maximum at the middle strike if GASS settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current GASS IV rank near 7.93% 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 GASS at 49.60%. As a Industrials name, GASS options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to GASS-specific events.
GASS 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. GASS positions also carry Industrials sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move GASS alongside the broader basket even when GASS-specific fundamentals are unchanged. Always rebuild the position from current GASS chain quotes before placing a trade.

- How are GASS butterfly max profit and max loss calculated?
