How are FCEL 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 FCEL butterfly priced from the end-of-day chain at a 30-day expiry (ATM IV 158.58%), the computed maximum profit is $174.60 per contract and the computed maximum loss is -$25.00 per contract. Live intraday quotes will differ as the chain moves through the trading session.

What is the breakeven for a FCEL butterfly?

The breakeven for the FCEL butterfly priced on this page is roughly $31.75 at expiration, derived from end-of-day chain premiums.

Current FCEL snapshot

As of June 29, 2026, spot at $30.45, ATM IV 158.58%, IV rank 58.59%, expected move 45.46%. The butterfly on FCEL 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 31-day expiry.

Why this butterfly structure on FCEL specifically: FCEL IV at 158.58% 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 45.46% (roughly $13.84 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 FCEL expiries trade a higher absolute premium for lower per-day decay. Position sizing on FCEL should anchor to the underlying notional of $30.45 per share and to the trader's directional view on FCEL stock.

FCEL butterfly setup

The FCEL 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 FCEL near $30.45, the first option leg uses a $29.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed FCEL 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 FCEL shares for the stock leg in covered calls and collars).

Action	Type	Strike / Basis	Premium (est)
Buy 1	Call	$29.00	$10.75
Sell 2	Call	$30.00	$10.20
Buy 1	Call	$32.00	$8.90

When traders use butterfly on FCEL

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

FCEL thesis for this butterfly

The market-implied 1-standard-deviation range for FCEL extends from approximately $16.61 on the downside to $44.29 on the upside. A FCEL long call butterfly is a pinning play: it pays maximum at the middle strike if FCEL settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current FCEL IV rank near 58.59% is mid-range against its 1-year distribution, so the IV signal is neutral; the butterfly thesis on FCEL should anchor more to the directional view and the expected-move geometry. As a Industrials name, FCEL options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to FCEL-specific events.

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