Current KEX snapshot
As of May 13, 2026, spot at $146.47, ATM IV 31.00%, IV rank 35.05%, expected move 8.89%. The iron condor on KEX 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 iron condor structure on KEX specifically: KEX IV at 31.00% is mid-range versus its 1-year history, so the credit collected on a KEX iron condor sits in line with its long-run distribution, with a market-implied 1-standard-deviation move of approximately 8.89% (roughly $13.02 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 KEX expiries trade a higher absolute premium for lower per-day decay. Position sizing on KEX should anchor to the underlying notional of $146.47 per share and to the trader's directional view on KEX stock.
KEX iron condor setup
The KEX iron condor below is built from the end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With KEX near $146.47, the first option leg uses a $155.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed KEX 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 KEX shares for the stock leg in covered calls and collars).

| Sell 1 | Call | $155.00 | $2.35 |

KEX thesis for this iron condor
The market-implied 1-standard-deviation range for KEX extends from approximately $133.45 on the downside to $159.49 on the upside. A KEX iron condor is a delta-neutral premium-collection structure that pays off when KEX stays inside the inner short strikes through expiration; the wing width should reflect the trader's tolerance for the maximum loss scenario where the underlying breaches an outer strike. Current KEX IV rank near 35.05% is mid-range against its 1-year distribution, so the IV signal is neutral; the iron condor thesis on KEX should anchor more to the directional view and the expected-move geometry. As a Industrials name, KEX options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to KEX-specific events.
KEX iron condor positions are structurally neutral / range-bound; 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. KEX positions also carry Industrials sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move KEX alongside the broader basket even when KEX-specific fundamentals are unchanged. Short-premium structures like a iron condor on KEX carry tail risk when realized volatility exceeds the implied move; review historical KEX earnings reactions and macro stress periods before sizing. Always rebuild the position from current KEX chain quotes before placing a trade.
