T-Rex 2X Long MSTR Daily Target ETF (MSTU), launched under ETF Opportunities Trust in September 2024 and traded on the Cboe BZX Exchange, seeks daily investment results, before fees and expenses, equal to 200% of the daily performance of MicroStrategy Incorporated common stock (NASDAQ: MSTR). The fund achieves its leveraged exposure through derivatives including swaps and options, with primary holdings comprising pledged collateral positions from counterparties such as Clear Street, Natixis, Marex, BMO, and Cantor, alongside cash and short positions; it features a net expense ratio of 1.05% and targets sophisticated investors employing it as a short-term trading vehicle due to volatility decay, compounding effects, and leverage risks. Headquartered effectively through its issuers REX Shares in New York and Tuttle Capital Management in Connecticut, MSTU operates in the U.S. market, serving traders seeking magnified exposure to MSTR—a software firm heavily positioned in bitcoin holdings—within the leveraged equity ETF segment.
In November 2025, REX Shares and Tuttle Capital Management announced and executed a 1-for-10 reverse share split for MSTU, effective after market close on December 2, 2025, with trading on a split-adjusted basis commencing December 3, 2025; this corporate action included a CUSIP change and cash redemption of fractional shares at split-adjusted net asset value, preserving total shareholder value absent fractional impacts. The reorganization addressed share price dynamics without altering the fund's investment objective or strategy, amid assets under management reaching approximately $1.16 billion as of late 2025. No other major acquisitions, funding rounds, partnerships, or product launches have been reported for the fund since inception.
