How are KNF butterfly max profit and max loss calculated?

Max profit equals the wing width minus net debit times 100 (reached when the underlying pins the middle strike); max loss equals the net debit times 100. Two breakevens at lower-wing plus debit and upper-wing minus debit. For the KNF butterfly priced from the August 14, 2026 end-of-day chain at a 30-day expiry (ATM IV 44.70%), the computed maximum profit is $184.50 per contract and the computed maximum loss is -$315.50 per contract. Live intraday quotes will differ as the chain moves through the trading session.

What is the breakeven for a KNF butterfly?

The breakeven for the KNF butterfly priced on this page is roughly $66.85 at expiration, derived from the August 14, 2026 end-of-day chain's premiums. Breakeven is the underlying price at which the strategy's P&L crosses zero ignoring transaction costs and assignment risk. The KNF market-implied 1-standard-deviation expected move in the same options snapshot is approximately 12.82%; if the move sits well outside the breakeven distance, the structure's risk-reward becomes correspondingly tighter.

KNF snapshot

As of August 14, 2026, spot at $66.02, ATM IV 44.70%, IV rank 3.31%, expected move 12.82%. The butterfly on KNF below is built from the August 14, 2026 end-of-day chain, with strikes snapped to listed contracts and premiums pulled from the bid/ask midpoint at a 7-day expiry.

Why this butterfly structure on KNF specifically: KNF IV at 44.70% is on the cheap side of its 1-year range, which favors premium-buying structures like a KNF butterfly, with a market-implied 1-standard-deviation move of approximately 12.82% (roughly $8.46 on the underlying). The 7-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated KNF expiries trade a higher absolute premium for lower per-day decay. Position sizing on KNF should anchor to the underlying notional of $66.02 per share and to the trader's directional view on KNF stock.

KNF butterfly setup

The KNF butterfly below is built from the August 14, 2026 end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With KNF at $66.02 on that close, the first option leg uses a $65.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed KNF chain at a 7-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 KNF shares for the stock leg in covered calls and collars).

Action	Type	Strike / Basis	Premium (est)
Buy 1	Call	$65.00	$2.48
Sell 2	Call	$65.00	$2.48
Buy 1	Call	$70.00	$0.63

When traders use butterfly on KNF

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

KNF thesis for this butterfly

The market-implied 1-standard-deviation range for KNF extends from approximately $57.56 on the downside to $74.48 on the upside. A KNF long call butterfly is a pinning play: it pays maximum at the middle strike if KNF settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current KNF IV rank near 3.31% sits in the lower third of its 1-year distribution, where IV often re-expands toward the mean; this favors premium-buying structures and disadvantages premium-selling structures on KNF at 44.70%. As a Basic Materials name, KNF options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to KNF-specific events.

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