How are CNP 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 CNP butterfly priced from the end-of-day chain at a 30-day expiry (ATM IV 19.00%), the computed maximum profit is $118.75 per contract and the computed maximum loss is -$75.00 per contract. Live intraday quotes will differ as the chain moves through the trading session.

What is the breakeven for a CNP butterfly?

The breakeven for the CNP butterfly priced on this page is roughly $42.75 and $45.25 at expiration, derived from end-of-day chain premiums.

Current CNP snapshot

As of June 30, 2026, spot at $44.28, ATM IV 19.00%, IV rank 40.33%, expected move 5.45%. The butterfly on CNP 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 CNP specifically: CNP IV at 19.00% 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 5.45% (roughly $2.41 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 CNP expiries trade a higher absolute premium for lower per-day decay. Position sizing on CNP should anchor to the underlying notional of $44.28 per share and to the trader's directional view on CNP stock.

CNP butterfly setup

The CNP 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 CNP near $44.28, the first option leg uses a $42.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed CNP 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 CNP shares for the stock leg in covered calls and collars).

Action	Type	Strike / Basis	Premium (est)
Buy 1	Call	$42.00	$3.18
Sell 2	Call	$44.00	$1.60
Buy 1	Call	$46.00	$0.78

When traders use butterfly on CNP

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

CNP thesis for this butterfly

The market-implied 1-standard-deviation range for CNP extends from approximately $41.87 on the downside to $46.69 on the upside. A CNP long call butterfly is a pinning play: it pays maximum at the middle strike if CNP settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current CNP IV rank near 40.33% is mid-range against its 1-year distribution, so the IV signal is neutral; the butterfly thesis on CNP should anchor more to the directional view and the expected-move geometry. As a Utilities name, CNP options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to CNP-specific events.

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