How are PEG 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 PEG butterfly priced from the end-of-day chain at a 30-day expiry (ATM IV 19.40%), the computed maximum profit is $208.45 per contract and the computed maximum loss is -$255.00 per contract. Live intraday quotes will differ as the chain moves through the trading session.

What is the breakeven for a PEG butterfly?

The breakeven for the PEG butterfly priced on this page is roughly $80.05 and $85.24 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 PEG market-implied 1-standard-deviation expected move is approximately 5.56%; if the move sits well outside the breakeven distance, the structure's risk-reward becomes correspondingly tighter.

How does current PEG implied volatility affect this butterfly?

PEG ATM IV is at 19.40% with IV rank near 10.69%, 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.

PEG Butterfly Strategy

PEG (Public Service Enterprise Group Incorporated), in the Utilities sector, (Regulated Electric industry), listed on NYSE.

Public Service Enterprise Group Incorporated (PSEG) is an energy provider primarily operating through its subsidiaries in the Northeastern and Mid-Atlantic United States. The company's business activities are structured into two primary segments: PSE&G and PSEG Power. The PSE&G division is responsible for transmitting electricity and distributing both electricity and natural gas to residential, commercial, and industrial customers. This segment also commits resources to solar power generation projects and various energy efficiency initiatives, as well as offering appliance service and repair. By December 31, 2021, its substantial infrastructure included 25,000 circuit miles of electric transmission and distribution systems, supported by 862,000 utility poles. It also featured 56 switching stations with a total capacity of 39,353 megavolt-amperes (MVA) and 235 substations with a combined capacity of 9,285 MVA.

PEG (Public Service Enterprise Group Incorporated) trades in the Utilities sector, specifically Regulated Electric, with a market capitalization of approximately $41.65B, a trailing P/E of 18.43, a beta of 0.53 versus the broader market, a 52-week range of 76.05-91.26, average daily share volume of 2.8M, a public-listing history dating back to 1980, approximately 13K full-time employees. These structural characteristics shape how PEG stock options price implied volatility around earnings windows, capital events, and macro-driven sector rotations.

A beta of 0.53 indicates PEG has historically moved less than the broader market, dampening realized volatility and producing tighter expected-move bands per unit of dollar exposure. PEG pays a dividend, which adjusts put-call parity and shifts the ex-dividend pricing across the listed chain.

What is a butterfly on PEG?

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.

Current PEG snapshot

As of June 30, 2026, spot at $81.63, ATM IV 19.40%, IV rank 10.69%, expected move 5.56%. The butterfly on PEG 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 52-day expiry.

Why this butterfly structure on PEG specifically: PEG IV at 19.40% is on the cheap side of its 1-year range, which favors premium-buying structures like a PEG butterfly, with a market-implied 1-standard-deviation move of approximately 5.56% (roughly $4.54 on the underlying). The 52-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated PEG expiries trade a higher absolute premium for lower per-day decay. Position sizing on PEG should anchor to the underlying notional of $81.63 per share and to the trader's directional view on PEG stock.

PEG butterfly setup

The PEG 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 PEG near $81.63, the first option leg uses a $77.50 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed PEG chain at a 52-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 PEG shares for the stock leg in covered calls and collars).

Action	Type	Strike / Basis	Premium (est)
Buy 1	Call	$77.50	$5.90
Sell 2	Call	$82.50	$2.40
Buy 1	Call	$85.00	$1.45

When traders use butterfly on PEG

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

PEG thesis for this butterfly

The market-implied 1-standard-deviation range for PEG extends from approximately $77.09 on the downside to $86.17 on the upside. A PEG long call butterfly is a pinning play: it pays maximum at the middle strike if PEG settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current PEG IV rank near 10.69% 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 PEG at 19.40%. As a Utilities name, PEG options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to PEG-specific events.

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