Current KDEF snapshot

As of May 13, 2026, spot at $56.55, ATM IV 56.50%, IV rank 32.35%, expected move 16.20%. The butterfly on KDEF 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 KDEF specifically: KDEF IV at 56.50% 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 16.20% (roughly $9.16 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 KDEF expiries trade a higher absolute premium for lower per-day decay. Position sizing on KDEF should anchor to the underlying notional of $56.55 per share and to the trader's directional view on KDEF etf.

KDEF butterfly setup

The KDEF 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 KDEF near $56.55, the first option leg uses a $54.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed KDEF 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 KDEF shares for the stock leg in covered calls and collars).

When traders use butterfly on KDEF

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

KDEF thesis for this butterfly

The market-implied 1-standard-deviation range for KDEF extends from approximately $47.39 on the downside to $65.71 on the upside. A KDEF long call butterfly is a pinning play: it pays maximum at the middle strike if KDEF settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current KDEF IV rank near 32.35% is mid-range against its 1-year distribution, so the IV signal is neutral; the butterfly thesis on KDEF should anchor more to the directional view and the expected-move geometry. As a Financial Services name, KDEF options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to KDEF-specific events.

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