How are CSX 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 CSX straddle priced from the end-of-day chain at a 30-day expiry (ATM IV 28.28%), the computed maximum profit is unbounded per contract and the computed maximum loss is -$307.95 per contract. Live intraday quotes will differ as the chain moves through the trading session.

What is the breakeven for a CSX straddle?

The breakeven for the CSX straddle priced on this page is roughly $44.83 and $51.18 at expiration, derived from end-of-day chain premiums.

Current CSX snapshot

As of June 30, 2026, spot at $47.66, ATM IV 28.28%, IV rank 32.09%, expected move 8.11%. The straddle on CSX 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 31-day expiry.

Why this straddle structure on CSX specifically: CSX IV at 28.28% 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 8.11% (roughly $3.86 on the underlying). The 31-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated CSX expiries trade a higher absolute premium for lower per-day decay. Position sizing on CSX should anchor to the underlying notional of $47.66 per share and to the trader's directional view on CSX stock.

CSX straddle setup

The CSX 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 CSX near $47.66, the first option leg uses a $48.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed CSX chain at a 31-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 CSX shares for the stock leg in covered calls and collars).

Action	Type	Strike / Basis	Premium (est)
Buy 1	Call	$48.00	$1.53
Buy 1	Put	$48.00	$1.65

When traders use straddle on CSX

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

CSX thesis for this straddle

The market-implied 1-standard-deviation range for CSX extends from approximately $43.80 on the downside to $51.52 on the upside. A CSX 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 CSX IV rank near 32.09% is mid-range against its 1-year distribution, so the IV signal is neutral; the straddle thesis on CSX should anchor more to the directional view and the expected-move geometry. As a Industrials name, CSX options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to CSX-specific events.

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