How are BMNU 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 BMNU butterfly priced from the September 29, 2026 end-of-day chain at a 30-day expiry (ATM IV 146.20%), the computed maximum profit is $89.46 per contract and the computed maximum loss is -$5.00 per contract. Live intraday quotes will differ as the chain moves through the trading session.

What is the breakeven for a BMNU butterfly?

The breakeven for the BMNU butterfly priced on this page is roughly $20.00 and $21.96 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 BMNU market-implied 1-standard-deviation expected move in the same options snapshot is approximately 41.91%; if the move sits well outside the breakeven distance, the structure's risk-reward becomes correspondingly tighter.

BMNU Butterfly Strategy

BMNU (ETF Opportunities Trust - T-Rex 2x Long BMNR Daily Target ETF), in the Financial Services sector, (Asset Management industry), listed on CBOE.

BMNU is designed for making bullish bets on the stock price of Bitmine Immersion Technologies, Inc. through swap agreements. The objective is to obtain daily leveraged exposure equivalent to 200% of the fund's net assets. To maintain this exposure, daily rebalancing is performed to make adjustments in response to BMNR's daily price movements. As a geared product, the fund is intended as a short-term tactical tool, rather than as a long-term investment vehicle. As a result, returns may deviate from the expected 2x if held for longer than a single day due to compounding. This strategy is high-risk and does not include a defensive position as part of its overall process.

BMNU (ETF Opportunities Trust - T-Rex 2x Long BMNR Daily Target ETF) trades in the Financial Services sector, specifically Asset Management, with a market capitalization of approximately $446.2M, a beta of 2.68 versus the broader market, a 52-week range of 6.1-425.6, average daily share volume of 6.7M, a public-listing history dating back to 2025. These structural characteristics shape how BMNU etf options price implied volatility around earnings windows, capital events, and macro-driven sector rotations.

A beta of 2.68 indicates BMNU has historically moved more than the broader market, amplifying both the directional payoff and the realized volatility relative to an index-equivalent position.

What is a butterfly on BMNU?

BMNU snapshot

As of September 29, 2026, spot at $21.26, ATM IV 146.20%, IV rank 35.77%, expected move 41.91%. The butterfly on BMNU 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 17-day expiry.

Why this butterfly structure on BMNU specifically: BMNU IV at 146.20% 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 41.91% (roughly $8.91 on the underlying). The 17-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated BMNU expiries trade a higher absolute premium for lower per-day decay. Position sizing on BMNU should anchor to the underlying notional of $21.26 per share and to the trader's directional view on BMNU etf.

BMNU butterfly setup

The BMNU 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 BMNU at $21.26 on that close, the first option leg uses a $20.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed BMNU chain at a 17-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 BMNU shares for the stock leg in covered calls and collars).

Action	Type	Strike / Basis	Premium (est)
Buy 1	Call	$20.00	$3.20
Sell 2	Call	$21.00	$2.75
Buy 1	Call	$22.00	$2.35

When traders use butterfly on BMNU

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

BMNU thesis for this butterfly

The market-implied 1-standard-deviation range for BMNU extends from approximately $12.35 on the downside to $30.17 on the upside. A BMNU long call butterfly is a pinning play: it pays maximum at the middle strike if BMNU settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current BMNU IV rank near 35.77% is mid-range against its 1-year distribution, so the IV signal is neutral; the butterfly thesis on BMNU should anchor more to the directional view and the expected-move geometry. As a Financial Services name, BMNU options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to BMNU-specific events.

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