Current KEX snapshot

As of June 30, 2026, spot at $136.07, ATM IV 32.60%, IV rank 38.67%, expected move 9.35%. 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 17-day expiry.

Why this iron condor structure on KEX specifically: KEX IV at 32.60% 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 9.35% (roughly $12.72 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 KEX expiries trade a higher absolute premium for lower per-day decay. Position sizing on KEX should anchor to the underlying notional of $136.07 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 $136.07, the first option leg uses a $145.00 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 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 KEX shares for the stock leg in covered calls and collars).

KEX thesis for this iron condor

The market-implied 1-standard-deviation range for KEX extends from approximately $123.35 on the downside to $148.79 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 38.67% 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.
