BMNU Cash-Secured Put 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.

This strategy is high-risk and does not include a defensive position as part of its overall process.

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.

BMNU snapshot
As of September 29, 2026, spot at $21.26, ATM IV 146.20%, IV rank 35.77%, expected move 41.91%. The cash-secured put 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 cash-secured put structure on BMNU specifically: BMNU IV at 146.20% is mid-range versus its 1-year history, so the credit collected on a BMNU cash-secured put sits in line with its long-run distribution, 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 cash-secured put setup
The BMNU cash-secured put 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).

BMNU thesis for this cash-secured put
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 cash-secured put lets a trader earn premium while waiting to acquire BMNU at the strike price; the strategy is most attractive when the trader is comfortable holding the underlying at that level and IV is rich enough to compensate for the assignment risk. Current BMNU IV rank near 35.77% is mid-range against its 1-year distribution, so the IV signal is neutral; the cash-secured put 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 cash-secured put positions are structurally neutral to slightly bullish; 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. Short-premium structures like a cash-secured put on BMNU carry tail risk when realized volatility exceeds the implied move; review historical BMNU earnings reactions and macro stress periods before sizing. Always rebuild the position from current BMNU chain quotes before placing a trade.
