These structural characteristics shape how CSX stock options price implied volatility around earnings windows, capital events, and macro-driven sector rotations.

What is a butterfly on CSX?
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.
CSX snapshot
As of August 14, 2026, spot at $50.13, ATM IV 19.80%, IV rank 4.41%, expected move 5.68%. The butterfly on CSX 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 28-day expiry.
Why this butterfly structure on CSX specifically: CSX IV at 19.80% is on the cheap side of its 1-year range, which favors premium-buying structures like a CSX butterfly, with a market-implied 1-standard-deviation move of approximately 5.68% (roughly $2.85 on the underlying). The 28-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 $50.13 per share and to the trader's directional view on CSX stock.
CSX butterfly setup
The CSX 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 CSX at $50.13 on that close, 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 28-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 | $2.65 |
| Sell 2 | Call | $50.00 | $1.15 |
| Buy 1 | Call | $53.00 | $0.25 |

When traders use butterfly on CSX
Butterflies on CSX are pinning bets - traders use them when they expect CSX 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.
CSX thesis for this butterfly
The market-implied 1-standard-deviation range for CSX extends from approximately $47.28 on the downside to $52.98 on the upside. A CSX long call butterfly is a pinning play: it pays maximum at the middle strike if CSX settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current CSX IV rank near 4.41% 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 CSX at 19.80%. 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 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. 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.
