How are BKLN 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 BKLN butterfly priced from the August 14, 2026 end-of-day chain at a 30-day expiry (ATM IV 18.77%), the computed maximum profit is $75.67 per contract and the computed maximum loss is -$20.50 per contract. Live intraday quotes will differ as the chain moves through the trading session.

What is the breakeven for a BKLN butterfly?

The breakeven for the BKLN butterfly priced on this page is roughly $19.71 and $21.30 at expiration, derived from the August 14, 2026 end-of-day chain's premiums.

BKLN Butterfly Strategy

BKLN (Invesco Senior Loan ETF), in the Financial Services sector, (Asset Management - Bonds industry), listed on AMEX.

The Invesco Senior Loan ETF, referred to as "the Fund," seeks to mirror the performance of its underlying benchmark, the Morningstar LSTA US Leveraged Loan 100 Index. This Index is specifically structured to track the market-weighted returns of prominent institutional leveraged loans, taking into account their market valuations, associated spreads, and interest payments. To achieve its investment goal, the Fund typically allocates a minimum of 80% of its total assets to securities found within this Index. However, instead of acquiring every single component, the Fund employs a "sampling" strategy, investing in a representative selection of these securities. Both the Fund's portfolio and the Index itself undergo adjustments and re-evaluations semi-annually, occurring each June and December.

BKLN (Invesco Senior Loan ETF) trades in the Financial Services sector, specifically Asset Management - Bonds, with a market capitalization of approximately $7.19B, a beta of 0.03 versus the broader market, a 52-week range of 20.11-21.07, average daily share volume of 8.9M, a public-listing history dating back to 2011. These structural characteristics shape how BKLN etf options price implied volatility around earnings windows, capital events, and macro-driven sector rotations.

BKLN snapshot

As of August 14, 2026, spot at $20.56, ATM IV 18.77%, IV rank 3.41%, expected move 5.38%. The butterfly on BKLN 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 28-day expiry.

Why this butterfly structure on BKLN specifically: BKLN IV at 18.77% is on the cheap side of its 1-year range, which favors premium-buying structures like a BKLN butterfly, with a market-implied 1-standard-deviation move of approximately 5.38% (roughly $1.11 on the underlying). The 28-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated BKLN expiries trade a higher absolute premium for lower per-day decay. Position sizing on BKLN should anchor to the underlying notional of $20.56 per share and to the trader's directional view on BKLN etf.

BKLN butterfly setup

The BKLN 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 BKLN at $20.56 on that close, the first option leg uses a $19.50 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed BKLN chain at a 28-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 BKLN shares for the stock leg in covered calls and collars).

Action	Type	Strike / Basis	Premium (est)
Buy 1	Call	$19.50	$1.08
Sell 2	Call	$20.50	$0.52
Buy 1	Call	$21.50	$0.17

When traders use butterfly on BKLN

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

BKLN thesis for this butterfly

The market-implied 1-standard-deviation range for BKLN extends from approximately $19.45 on the downside to $21.67 on the upside. A BKLN long call butterfly is a pinning play: it pays maximum at the middle strike if BKLN settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current BKLN IV rank near 3.41% 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 BKLN at 18.77%. As a Financial Services name, BKLN options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to BKLN-specific events.

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