How are FEPI 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 FEPI butterfly priced from the August 14, 2026 end-of-day chain at a 30-day expiry (ATM IV 15.90%), the computed maximum profit is $72.79 per contract and the computed maximum loss is -$110.00 per contract. Live intraday quotes will differ as the chain moves through the trading session.

What is the breakeven for a FEPI butterfly?

The breakeven for the FEPI butterfly priced on this page is roughly $41.10 and $42.90 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 FEPI market-implied 1-standard-deviation expected move in the same options snapshot is approximately 4.56%; if the move sits well outside the breakeven distance, the structure's risk-reward becomes correspondingly tighter.

How does current FEPI implied volatility affect this butterfly?

FEPI ATM IV is at 15.90% with IV rank near 2.06%, 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.

FEPI Butterfly Strategy

FEPI (REX FANG & Innovation Equity Premium Income ETF), in the Financial Services sector, (Asset Management - Income industry), listed on NASDAQ.

The REX FANG & Innovation Equity Premium Income ETF, or FEPI, utilizes a covered call strategy designed to achieve two main goals: generating income and providing exposure to potential growth within the technology sector. The fund accomplishes this by maintaining positions in the stocks comprising its benchmark, the Solactive FANG Innovation Index, and simultaneously selling call options on these shares that are slightly out-of-the-money. This approach leverages the significant volatility often found in major technology companies, thereby earning premium income from the options. However, it also means that some of the potential upside from stock appreciation is capped. An additional benefit is a modest safeguard against drops in stock prices. It's important to recognize, though, that this protective buffer is confined to the option premiums received and may not completely negate substantial declines in the underlying securities.

FEPI (REX FANG & Innovation Equity Premium Income ETF) trades in the Financial Services sector, specifically Asset Management - Income, with a market capitalization of approximately $689.7M, a beta of 1.10 versus the broader market, a 52-week range of 37.9-49.68, average daily share volume of 204K, a public-listing history dating back to 2023. These structural characteristics shape how FEPI etf options price implied volatility around earnings windows, capital events, and macro-driven sector rotations.

A beta of 1.10 places FEPI roughly in line with broader market moves, so the strategy payoff and realized volatility track the index-equivalent baseline. FEPI pays a dividend, which adjusts put-call parity and shifts the ex-dividend pricing across the listed chain.

What is a butterfly on FEPI?

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.

FEPI snapshot

As of August 14, 2026, spot at $42.38, ATM IV 15.90%, IV rank 2.06%, expected move 4.56%. The butterfly on FEPI 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 35-day expiry.

Why this butterfly structure on FEPI specifically: FEPI IV at 15.90% is on the cheap side of its 1-year range, which favors premium-buying structures like a FEPI butterfly, with a market-implied 1-standard-deviation move of approximately 4.56% (roughly $1.93 on the underlying). The 35-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated FEPI expiries trade a higher absolute premium for lower per-day decay. Position sizing on FEPI should anchor to the underlying notional of $42.38 per share and to the trader's directional view on FEPI etf.

FEPI butterfly setup

The FEPI 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 FEPI at $42.38 on that close, the first option leg uses a $40.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed FEPI chain at a 35-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 FEPI shares for the stock leg in covered calls and collars).

Action	Type	Strike / Basis	Premium (est)
Buy 1	Call	$40.00	$2.65
Sell 2	Call	$42.00	$1.03
Buy 1	Call	$44.00	$0.50

When traders use butterfly on FEPI

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

FEPI thesis for this butterfly

The market-implied 1-standard-deviation range for FEPI extends from approximately $40.45 on the downside to $44.31 on the upside. A FEPI long call butterfly is a pinning play: it pays maximum at the middle strike if FEPI settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current FEPI IV rank near 2.06% 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 FEPI at 15.90%. As a Financial Services name, FEPI options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to FEPI-specific events.

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