How are PFSI 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 PFSI butterfly priced from the August 14, 2026 end-of-day chain at a 30-day expiry (ATM IV 33.20%), the computed maximum profit is $275.00 per contract and the computed maximum loss is -$225.00 per contract. Live intraday quotes will differ as the chain moves through the trading session.

What is the breakeven for a PFSI butterfly?

The breakeven for the PFSI butterfly priced on this page is roughly $77.25 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 PFSI market-implied 1-standard-deviation expected move in the same options snapshot is approximately 9.52%; if the move sits well outside the breakeven distance, the structure's risk-reward becomes correspondingly tighter.

How does current PFSI implied volatility affect this butterfly?

PFSI ATM IV is at 33.20% with IV rank near 5.09%, which is on the low end of its 1-year range. Premium-buying structures (long call, long put, debit spreads) are relatively cheap in this regime; premium-selling structures collect less credit per unit risk.

PFSI Butterfly Strategy

PFSI (PennyMac Financial Services, Inc.), in the Financial Services sector, (Financial - Mortgages industry), listed on NYSE.

PennyMac Financial Services, Inc. (PFSI), through its various subsidiaries, is actively engaged in mortgage banking and investment management activities across the United States. The company's operations are structured into three primary divisions: Production, Servicing, and Investment Management. The Production segment focuses on the creation, acquisition, and subsequent sale of loans. Its primary involvement is with first-lien residential mortgage loans, encompassing both conventional products and those insured or guaranteed by the government. The Servicing segment is responsible for the administration of newly originated loans, in addition to managing early buyout transactions and providing servicing for other loan portfolios. This involves a broad range of activities, such as general loan administration, payment collection, and managing defaults.

PFSI (PennyMac Financial Services, Inc.) trades in the Financial Services sector, specifically Financial - Mortgages, with a market capitalization of approximately $4.00B, a trailing P/E of 10.19, a beta of 1.44 versus the broader market, a 52-week range of 71.68-160.36, average daily share volume of 577K, a public-listing history dating back to 2013, approximately 6K full-time employees. These structural characteristics shape how PFSI stock options price implied volatility around earnings windows, capital events, and macro-driven sector rotations.

A beta of 1.44 indicates PFSI has historically moved more than the broader market, amplifying both the directional payoff and the realized volatility relative to an index-equivalent position. The trailing P/E of 10.19 is on the value side, where IV often compresses outside event windows because forward growth expectations are already discounted into the share price. PFSI pays a dividend, which adjusts put-call parity and shifts the ex-dividend pricing across the listed chain.

What is a butterfly on PFSI?

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.

PFSI snapshot

As of August 14, 2026, spot at $78.09, ATM IV 33.20%, IV rank 5.09%, expected move 9.52%. The butterfly on PFSI 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 PFSI specifically: PFSI IV at 33.20% is on the cheap side of its 1-year range, which favors premium-buying structures like a PFSI butterfly, with a market-implied 1-standard-deviation move of approximately 9.52% (roughly $7.43 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 PFSI expiries trade a higher absolute premium for lower per-day decay. Position sizing on PFSI should anchor to the underlying notional of $78.09 per share and to the trader's directional view on PFSI stock.

PFSI butterfly setup

The PFSI 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 PFSI at $78.09 on that close, the first option leg uses a $75.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed PFSI 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 PFSI shares for the stock leg in covered calls and collars).

Action	Type	Strike / Basis	Premium (est)
Buy 1	Call	$75.00	$3.25
Sell 2	Call	$80.00	$1.00
Buy 1	Call	$80.00	$1.00

When traders use butterfly on PFSI

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

PFSI thesis for this butterfly

The market-implied 1-standard-deviation range for PFSI extends from approximately $70.66 on the downside to $85.52 on the upside. A PFSI long call butterfly is a pinning play: it pays maximum at the middle strike if PFSI settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current PFSI IV rank near 5.09% 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 PFSI at 33.20%. As a Financial Services name, PFSI options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to PFSI-specific events.

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