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 bear put spread 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 bear put spread structure on KEX specifically: KEX IV at 31.00% 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 8.89% (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 bear put spread setup
The KEX bear put spread 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 $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 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).

|---|---|---|---|
| Buy 1 | Put | $145.00 | $4.30 |
| Sell 1 | Put | $140.00 | $2.95 |

KEX thesis for this bear put spread
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 bear put spread caps both the risk and the reward of a bearish position; relative to an outright long put on KEX, the spread reduces the cost basis but limits the maximum profit to the strike width minus net debit. Current KEX IV rank near 35.05% is mid-range against its 1-year distribution, so the IV signal is neutral; the bear put spread 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 bear put spread positions are structurally moderately bearish; 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. Long-premium structures like a bear put spread on KEX are particularly exposed to IV-crush risk through scheduled events (earnings, FDA decisions, central-bank meetings) where IV typically contracts post-event regardless of the directional outcome. Always rebuild the position from current KEX chain quotes before placing a trade.
