MRTN Butterfly Strategy
MRTN (Marten Transport, Ltd.), in the Industrials sector, (Trucking industry), listed on NASDAQ.
Marten Transport, Ltd. operates as a temperature-sensitive truckload carrier for shippers in the United States, Canada, and Mexico. It operates through four segments: Truckload, Dedicated, Intermodal, and Brokerage. The Truckload segment transports food and other consumer packaged goods that require a temperature-controlled or insulated environment. The Dedicated segment offers customized transportation solutions for individual customers' requirements using temperature-controlled trailers, dry vans, and other specialized equipment. The Intermodal segment transports customers' freight utilizing its refrigerated containers and temperature-controlled trailers on railroad flatcars for portions of trips, as well as using tractors and contracted carriers. The Brokerage segment develops contractual relationships with and arranges for third-party carriers to transport freight for customers in temperature-controlled trailers and dry vans.
MRTN (Marten Transport, Ltd.) trades in the Industrials sector, specifically Trucking, with a market capitalization of approximately $1.22B, a trailing P/E of 84.38, a beta of 0.92 versus the broader market, a 52-week range of 9.35-15.84, average daily share volume of 797K, a public-listing history dating back to 1986, approximately 4K full-time employees. These structural characteristics shape how MRTN stock options price implied volatility around earnings windows, capital events, and macro-driven sector rotations.
A beta of 0.92 places MRTN roughly in line with broader market moves, so the strategy payoff and realized volatility track the index-equivalent baseline. The trailing P/E of 84.38 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. MRTN pays a dividend, which adjusts put-call parity and shifts the ex-dividend pricing across the listed chain.
What is a butterfly on MRTN?
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 MRTN snapshot
As of May 15, 2026, spot at $15.64, ATM IV 33.40%, IV rank 4.37%, expected move 9.58%. The butterfly on MRTN 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 MRTN specifically: MRTN IV at 33.40% is on the cheap side of its 1-year range, which favors premium-buying structures like a MRTN butterfly, with a market-implied 1-standard-deviation move of approximately 9.58% (roughly $1.50 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 MRTN expiries trade a higher absolute premium for lower per-day decay. Position sizing on MRTN should anchor to the underlying notional of $15.64 per share and to the trader's directional view on MRTN stock.
MRTN butterfly setup
The MRTN 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 MRTN near $15.64, the first option leg uses a $14.86 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed MRTN 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 MRTN shares for the stock leg in covered calls and collars).

MRTN thesis for this butterfly
The market-implied 1-standard-deviation range for MRTN extends from approximately $14.14 on the downside to $17.14 on the upside. A MRTN long call butterfly is a pinning play: it pays maximum at the middle strike if MRTN settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current MRTN IV rank near 4.37% 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 MRTN at 33.40%. As a Industrials name, MRTN options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to MRTN-specific events.
MRTN 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. MRTN positions also carry Industrials sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move MRTN alongside the broader basket even when MRTN-specific fundamentals are unchanged. Always rebuild the position from current MRTN chain quotes before placing a trade.
