How are PFE 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 PFE butterfly priced from the September 29, 2026 end-of-day chain at a 30-day expiry (ATM IV 24.07%), the computed maximum profit is $108.13 per contract and the computed maximum loss is -$39.00 per contract. Live intraday quotes will differ as the chain moves through the trading session.

What is the breakeven for a PFE butterfly?

The breakeven for the PFE butterfly priced on this page is roughly $27.39 and $29.61 at expiration, derived from the September 29, 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 PFE market-implied 1-standard-deviation expected move in the same options snapshot is approximately 6.90%; if the move sits well outside the breakeven distance, the structure's risk-reward becomes correspondingly tighter.

How does current PFE implied volatility affect this butterfly?

PFE ATM IV is at 24.07% with IV rank near 38.57%, which is mid-range against its 1-year history. Strategy selection depends more on directional thesis and expected move than on a strong IV signal.

PFE (Pfizer Inc.) trades in the Healthcare sector, specifically Drug Manufacturers - General, with a market capitalization of approximately $162.55B, a trailing P/E of 37.49, a beta of 0.30 versus the broader market, a 52-week range of 23.62-29.21, average daily share volume of 39.3M, a public-listing history dating back to 1972, approximately 75K full-time employees. These structural characteristics shape how PFE stock options price implied volatility around earnings windows, capital events, and macro-driven sector rotations.

A beta of 0.30 indicates PFE has historically moved less than the broader market, dampening realized volatility and producing tighter expected-move bands per unit of dollar exposure. The trailing P/E of 37.49 is on the rich side, which tends to correlate with higher earnings-window IV expansion as the market debates whether forward growth supports the multiple. PFE pays a dividend, which adjusts put-call parity and shifts the ex-dividend pricing across the listed chain.

What is a butterfly on PFE?

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.

PFE snapshot

As of September 29, 2026, spot at $28.61, ATM IV 24.07%, IV rank 38.57%, expected move 6.90%. The butterfly on PFE below is built from the September 29, 2026 end-of-day chain, with strikes snapped to listed contracts and premiums pulled from the bid/ask midpoint at a 31-day expiry.

Why this butterfly structure on PFE specifically: PFE IV at 24.07% 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 6.90% (roughly $1.97 on the underlying). The 31-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated PFE expiries trade a higher absolute premium for lower per-day decay. Position sizing on PFE should anchor to the underlying notional of $28.61 per share and to the trader's directional view on PFE stock.

PFE butterfly setup

The PFE butterfly below is built from the September 29, 2026 end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With PFE at $28.61 on that close, the first option leg uses a $27.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed PFE chain at a 31-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 PFE shares for the stock leg in covered calls and collars).

Action	Type	Strike / Basis	Premium (est)
Buy 1	Call	$27.00	$1.89
Sell 2	Call	$28.50	$0.91
Buy 1	Call	$30.00	$0.32

When traders use butterfly on PFE

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

PFE thesis for this butterfly

The market-implied 1-standard-deviation range for PFE extends from approximately $26.64 on the downside to $30.58 on the upside. A PFE long call butterfly is a pinning play: it pays maximum at the middle strike if PFE settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current PFE IV rank near 38.57% is mid-range against its 1-year distribution, so the IV signal is neutral; the butterfly thesis on PFE should anchor more to the directional view and the expected-move geometry. As a Healthcare name, PFE options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to PFE-specific events.

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