MSTZ Butterfly Strategy

MSTZ (T-REX 2X Inverse MSTR Daily Target ETF), in the Financial Services sector, (Asset Management - Leveraged industry), listed on CBOE.

This fund generally commits a minimum of 80% of its net assets, along with any borrowed capital for investment purposes, into swap agreements. These agreements are structured to provide a daily return that aims to be 200% inverse (twice the opposite) of the performance of MSTR. MSTR refers to MicroStrategy Inc., an enterprise specializing in analytics and mobility software solutions. It's important to note that this fund maintains a non-diversified portfolio.

MSTZ (T-REX 2X Inverse MSTR Daily Target ETF) trades in the Financial Services sector, specifically Asset Management - Leveraged, with a market capitalization of approximately $44.6M, a beta of -3.61 versus the broader market, a 52-week range of 2.2-28.71, average daily share volume of 23.7M, a public-listing history dating back to 2024. These structural characteristics shape how MSTZ etf options price implied volatility around earnings windows, capital events, and macro-driven sector rotations.

A beta of -3.61 indicates MSTZ has historically moved less than the broader market, dampening realized volatility and producing tighter expected-move bands per unit of dollar exposure.

What is a butterfly on MSTZ?

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.

MSTZ snapshot

As of September 29, 2026, spot at $2.71, ATM IV 53.40%, IV rank 15.03%, expected move 15.31%. The butterfly on MSTZ 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 MSTZ specifically: MSTZ IV at 53.40% is on the cheap side of its 1-year range, which favors premium-buying structures like a MSTZ butterfly, with a market-implied 1-standard-deviation move of approximately 15.31% (roughly $0.41 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 MSTZ expiries trade a higher absolute premium for lower per-day decay. Position sizing on MSTZ should anchor to the underlying notional of $2.71 per share and to the trader's directional view on MSTZ etf.

MSTZ butterfly setup

The MSTZ 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 MSTZ at $2.71 on that close, the first option leg uses a $2.57 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed MSTZ 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 MSTZ shares for the stock leg in covered calls and collars).

When traders use butterfly on MSTZ

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

MSTZ thesis for this butterfly

The market-implied 1-standard-deviation range for MSTZ extends from approximately $2.30 on the downside to $3.12 on the upside. A MSTZ long call butterfly is a pinning play: it pays maximum at the middle strike if MSTZ settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current MSTZ IV rank near 15.03% 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 MSTZ at 53.40%. As a Financial Services name, MSTZ options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to MSTZ-specific events.

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

Frequently asked questions

What is a butterfly on MSTZ?
A butterfly on MSTZ is the butterfly strategy applied to MSTZ (etf). The strategy is structurally neutral / pin (limited-risk, limited-reward): 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. With MSTZ etf at $2.71 on the September 29, 2026 close, the strikes shown on this page are snapped to the nearest listed MSTZ chain strike and the premiums come straight from that session's bid/ask midpoint.
How are MSTZ 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 MSTZ butterfly priced from the September 29, 2026 end-of-day chain at a 30-day expiry (ATM IV 53.40%), the computed maximum profit is unbounded per contract and the computed maximum loss is unbounded per contract. Live intraday quotes will differ as the chain moves through the trading session.
What is the breakeven for a MSTZ butterfly?

Breakeven is the underlying price at which the strategy's P&L crosses zero ignoring transaction costs and assignment risk. The MSTZ market-implied 1-standard-deviation expected move in the same options snapshot is approximately 15.31%; if the move sits well outside the breakeven distance, the structure's risk-reward becomes correspondingly tighter.
