How are KNX straddle max profit and max loss calculated?

Upside max profit is unbounded; downside max profit is bounded at the strike minus the combined call plus put debit (reached at zero). Max loss equals the combined debit times 100 (reached when the underlying pins to the strike). Two breakevens at strike plus debit and strike minus debit. For the KNX straddle priced from the end-of-day chain at a 30-day expiry (ATM IV 39.80%), the computed maximum profit is unbounded per contract and the computed maximum loss is -$510.27 per contract. Live intraday quotes will differ as the chain moves through the trading session.

What is the breakeven for a KNX straddle?

KNX Straddle Strategy

KNX (Knight-Swift Transportation Holdings Inc.), in the Industrials sector, (Trucking industry), listed on NYSE.

Knight-Swift Transportation Holdings Inc. (KNX) stands as a prominent provider of transportation services, specializing in truckload freight solutions for clients throughout the United States, Mexico, and Canada. Its operational scope is segmented into four key areas: Trucking, Logistics, Less-than-truckload (LTL), and Intermodal. Under its Trucking segment, the company manages a diverse portfolio of services, including irregular route, dedicated, temperature-controlled (refrigerated), flatbed, expedited, dry van, drayage, and cross-border transportation for a wide variety of goods and materials. Beyond its core trucking operations, Knight-Swift provides logistics and intermodal solutions, which include freight brokerage, intermodal services, comprehensive freight management, and various non-trucking offerings. The firm also extends a suite of support services, such as vehicle repair and maintenance, warranty coverage, insurance, equipment leasing, manufacturing and warehousing of trailer parts, and professional driver training through its academy. Additionally, Knight-Swift facilitates national transportation requirements through its regional direct services, utilizing third-party carriers to cover regions outside its proprietary network.

KNX (Knight-Swift Transportation Holdings Inc.) trades in the Industrials sector, specifically Trucking, with a market capitalization of approximately $12.45B, a trailing P/E of 366.09, a beta of 1.20 versus the broader market, a 52-week range of 38.63-82.86, average daily share volume of 4.1M, a public-listing history dating back to 1994, approximately 35K full-time employees. These structural characteristics shape how KNX stock options price implied volatility around earnings windows, capital events, and macro-driven sector rotations.

A beta of 1.20 places KNX roughly in line with broader market moves, so the strategy payoff and realized volatility track the index-equivalent baseline. The trailing P/E of 366.09 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. KNX pays a dividend, which adjusts put-call parity and shifts the ex-dividend pricing across the listed chain.

What is a straddle on KNX?

A long straddle buys an ATM call and an ATM put at the same strike, profiting from a large move in either direction; max loss equals the combined debit when the underlying pins to the strike at expiration.

Current KNX snapshot

As of June 30, 2026, spot at $78.16, ATM IV 39.80%, IV rank 41.24%, expected move 11.41%. The straddle on KNX 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 17-day expiry.

Why this straddle structure on KNX specifically: KNX IV at 39.80% 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 11.41% (roughly $8.92 on the underlying). The 17-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated KNX expiries trade a higher absolute premium for lower per-day decay. Position sizing on KNX should anchor to the underlying notional of $78.16 per share and to the trader's directional view on KNX stock.

KNX straddle setup

The KNX straddle below is built from the end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With KNX near $78.16, the first option leg uses a $77.50 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed KNX chain at a 17-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 KNX shares for the stock leg in covered calls and collars).

Action	Type	Strike / Basis	Premium (est)
Buy 1	Call	$77.50	$3.10
Buy 1	Put	$77.50	$2.28

When traders use straddle on KNX

Straddles on KNX are pure-volatility plays that profit from large moves in either direction; traders typically buy KNX straddles ahead of earnings, FDA decisions, or other catalysts where the realized move is expected to exceed the implied move priced into the chain.

KNX thesis for this straddle

The market-implied 1-standard-deviation range for KNX extends from approximately $69.24 on the downside to $87.08 on the upside. A KNX long straddle is a pure-volatility play: it profits when the underlying moves far enough from the strike in either direction to overcome the combined call plus put debit, regardless of direction. Current KNX IV rank near 41.24% is mid-range against its 1-year distribution, so the IV signal is neutral; the straddle thesis on KNX should anchor more to the directional view and the expected-move geometry. As a Industrials name, KNX options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to KNX-specific events.

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