KAI (Kadant Inc.) trades in the Industrials sector, specifically Industrial - Machinery, with a market capitalization of approximately $3.89B, a trailing P/E of 37.53, a beta of 1.19 versus the broader market, a 52-week range of 244.87-369.97, average daily share volume of 180K, a public-listing history dating back to 1992, approximately 4K full-time employees. These structural characteristics shape how KAI stock options price implied volatility around earnings windows, capital events, and macro-driven sector rotations.

A beta of 1.19 places KAI roughly in line with broader market moves, so the strategy payoff and realized volatility track the index-equivalent baseline. The trailing P/E of 37.53 is on the rich side, which tends to correlate with higher earnings-window IV expansion as the market debates whether forward growth supports the multiple. KAI pays a dividend, which adjusts put-call parity and shifts the ex-dividend pricing across the listed chain.

What is a butterfly on KAI?

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.

Current KAI snapshot

As of May 14, 2026, spot at $324.92, ATM IV 39.90%, IV rank 52.05%, expected move 11.44%. The butterfly on KAI 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 butterfly structure on KAI specifically: KAI IV at 39.90% 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 11.44% (roughly $37.17 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 KAI expiries trade a higher absolute premium for lower per-day decay. Position sizing on KAI should anchor to the underlying notional of $324.92 per share and to the trader's directional view on KAI stock.

KAI butterfly setup

The KAI butterfly below is built from the end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With KAI near $324.92, the first option leg uses a $310.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed KAI 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 KAI shares for the stock leg in covered calls and collars).

When traders use butterfly on KAI

Butterflies on KAI are pinning bets - traders use them when they expect KAI 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.

KAI thesis for this butterfly

The market-implied 1-standard-deviation range for KAI extends from approximately $287.75 on the downside to $362.09 on the upside. A KAI long call butterfly is a pinning play: it pays maximum at the middle strike if KAI settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current KAI IV rank near 52.05% is mid-range against its 1-year distribution, so the IV signal is neutral; the butterfly thesis on KAI should anchor more to the directional view and the expected-move geometry. As a Industrials name, KAI options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to KAI-specific events.

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