A $10,000 investment in T-Rex 2x Long MSTR Daily Target ETF (CBOE: MSTU) made on August 4, 2025 is worth roughly $255 today, representing a 97.45% loss.
The fund’s underlying stock, Strategy (NASDAQ: MSTR), fell 74.91% over that same period, making MSTU’s destruction of capital far steeper than even a brutal decline in the base asset would suggest.
MSTU is a Tuttle Capital product engineered to deliver two times the daily price move of Strategy, the Bitcoin treasury company run by CEO Phong Le that holds 846,000 BTC as of its Q2 2026 report.
The fund operates through swaps rather than direct share ownership, which is why its holdings file shows a stack of long and short Strategy derivative positions rather than plain equity.
Net assets sit at $525.4 million as of the May 31, 2026 NPORT filing, with total gross exposure of roughly $1.62 billion against $1.09 billion in liabilities, the unmistakable fingerprint of a leveraged wrapper.
The year-to-date numbers make the compounding damage even clearer, with MSTR down 35.74% in 2026 while MSTU has collapsed 77.02%, meaningfully worse than a simple 2x multiple would imply.
The culprit is volatility decay, a mechanism where a down 5% day followed by an up 5% day leaves a 2x fund at roughly 99.00 while the underlying sits at 99.75, and that gap compounds relentlessly across hundreds of trading sessions.
MSTR carries a beta of 3.555 and a 52-week range stretching from $81.81 to $414.36, making it one of the most volatile large-cap equities in the market and an especially punishing vehicle to double with daily resets.
Strategy’s Q2 2026 report, filed July 30, 2026, revealed an $8.22 billion net loss driven almost entirely by an $8.32 billion unrealized loss on digital assets, with revenue of $122.37 million up just 6.9% year over year.
CEO Phong Le told investors, “In the second quarter of 2026, Strategy strengthened its balance sheet while navigating a meaningful bitcoin price decline,” a measured description of what translated into near-total annihilation for leveraged holders.
The March 2026 VIX spike to 31.05 maps directly onto the ugliest stretch of MSTU’s chart, illustrating how macro volatility events accelerate the decay mechanism inside leveraged products tied to Bitcoin-correlated equities.
MSTU was designed as a short-term trading instrument, and on a contained timeframe it performs as advertised, gaining 1.60% in the past week against MSTR’s 1.55%, delivering clean daily 2x exposure.
The problem for long-term holders is that stretching daily resets across months of Bitcoin-driven whipsaws quietly consumes the position, regardless of whether the underlying eventually recovers.
With MSTR currently at $97.38, well below its $156.81 200-day moving average, analyst consensus sitting at a $257.50 price target, and MSTU trading under $2, a reverse split decision by the fund’s board is now a live question worth monitoring.
