How are PKB 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 PKB butterfly priced from the end-of-day chain at a 30-day expiry (ATM IV 30.80%), the computed maximum profit is $283.18 per contract and the computed maximum loss is -$180.00 per contract.

What is the breakeven for a PKB butterfly?

The breakeven for the PKB butterfly priced on this page is roughly $98.80 at expiration, derived from end-of-day chain premiums. Breakeven is the underlying price at which the strategy's P&L crosses zero ignoring transaction costs and assignment risk. The current PKB market-implied 1-standard-deviation expected move is approximately 8.83%; if the move sits well outside the breakeven distance, the structure's risk-reward becomes correspondingly tighter.

Current PKB snapshot

As of May 15, 2026, spot at $102.14, ATM IV 30.80%, IV rank 3.10%, expected move 8.83%. The butterfly on PKB 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 PKB specifically: PKB IV at 30.80% is on the cheap side of its 1-year range, which favors premium-buying structures like a PKB butterfly, with a market-implied 1-standard-deviation move of approximately 8.83% (roughly $9.02 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 PKB expiries trade a higher absolute premium for lower per-day decay. Position sizing on PKB should anchor to the underlying notional of $102.14 per share and to the trader's directional view on PKB etf.

PKB butterfly setup

The PKB 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 PKB near $102.14, the first option leg uses a $97.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed PKB 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 PKB shares for the stock leg in covered calls and collars).

Action	Type	Strike / Basis	Premium (est)
Buy 1	Call	$97.00	$7.20
Sell 2	Call	$102.00	$4.05
Buy 1	Call	$105.00	$2.70

When traders use butterfly on PKB

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

PKB thesis for this butterfly

The market-implied 1-standard-deviation range for PKB extends from approximately $93.12 on the downside to $111.16 on the upside. A PKB long call butterfly is a pinning play: it pays maximum at the middle strike if PKB settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current PKB IV rank near 3.10% 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 PKB at 30.80%. As a Financial Services name, PKB options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to PKB-specific events.

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