MSTU Down 95% in a Year, How a 2x Daily Fund Lost Nearly Everything While Its Underlying Fell 67%

A $10,000 stake in the T-REX 2X Long MSTR Daily Target ETF (NASDAQ:MSTU) bought at Thursday’s close was worth about $8,633 at Friday’s bell, a roughly 14% single-session drawdown from $3.95 to $3.41. The fund’s mirror product traveled the same path. The underlying, Strategy (NASDAQ:MSTR | MSTR Price Prediction), the company formerly known as MicroStrategy, fell about 7% from $129 to $120. Bitcoin broke below $60,786, which is the chain of cause and effect in one sentence.

That single day is the easy math. The harder math is what has happened to anyone who has held this ETF for any length of time. MSTU is down 44% over the past week, 61% over the past month, 59% year to date, and 95.4% over the past year. The one-year number is the one to sit with. A $74.10 share on June 5, 2025 is a $3.41 share today. Strategy itself fell about 67% over the same window, from $368.79 to $120.44. The leveraged wrapper did not double that loss. It nearly tripled it, and that gap is the entire story.

How a 2x Daily Fund Loses 95% in a Year

MSTU promises 2x the daily move of MSTR, with daily reset rather than cumulative tracking. The fund resets its exposure every afternoon, which means each day’s leverage starts fresh against the previous close. In a clean, low-volatility uptrend, that compounding works in the holder’s favor and the long-horizon return can exceed 2x the underlying. In anything else, and particularly in a choppy tape with sharp reversals, the daily reset bleeds value even when the underlying ends up in the same place. The math is the product itself.

Friday’s session is the clean version of the mechanism. Bitcoin fell, MSTR fell about 7%, the 2x wrapper delivered about 14%. The trigger upstream was a payrolls print of 172,000 against an 80,000 expectation that lifted the 2-year Treasury yield to 4.16%, a 16-month high, and pulled risk assets down with it. Bitcoin is down 23.4% over the past month and 41.3% over the past year, having reversed all of its post-election rally. MSTR is a leveraged proxy on bitcoin. MSTU is a leveraged proxy on the proxy. When the chain runs in reverse, the bottom link moves the most.

The Strategy capital structure makes the proxy relationship tighter on the way down than on the way up. The company holds 713,502 bitcoins at a cost basis of approximately $54.26 billion, and under ASU 2023-08 fair value accounting, every quarter’s bitcoin move flows straight through the income statement. Q4 2025 booked a $17.44 billion unrealized loss and a $12.44 billion net loss, with diluted EPS of -$42.93 against a consensus of -$15.66. The 8-K hit on February 5, 2026 with MSTR at $106, down from $269.20 at the Q3 filing on October 30, 2025 and $396.51 at the Q2 filing on July 31, 2025. The proxy worked in reverse for two straight quarters before Friday added another leg.

The Dilution Engine That Keeps Running

Strategy raised $25.3 billion in 2025, making it the largest U.S. equity issuer for the second consecutive year, and entered 2026 with over $37 billion remaining across its ATM programs, including $8.1 billion under the common stock ATM as of February 1, 2026. The company keeps issuing equity to buy bitcoin, which is fine when MSTR trades at a fat premium to its bitcoin NAV because each new share funds more BTC per existing share. When the premium compresses, the same machine becomes pure dilution. CEO Phong Le has described the flagship STRC preferred instrument and its 11.25% annualized dividend rate as the mechanism that has "helped maintain STRC price stability near the $100 stated amount despite a weaker bitcoin price environment." The dividend rate is the tell. It rises when bitcoin weakens, because the variable mechanism has to work harder to keep STRC near par.

Insider activity through the spring shows the picture. CFO Andrew Kang sold approximately 10,600 common shares between $163 and $166 on May 19, 2026, and director Jarrod Patten disposed of shares at prices ranging from $196 in early May down through $122 in early April. The pattern looks like Rule 10b5-1 plan execution rather than panic, but the calendar lines up with the slide that took MSTU from $8.84 a month ago to $3.41 Friday.

What Would Have to Change

The forward read on MSTU is a thesis on volatility more than a thesis on bitcoin direction. If bitcoin stabilizes and grinds higher in a low-volatility tape, MSTU can compound impressively off this base, exactly the way it compounded brutally on the way down. If bitcoin chops between $55,000 and $75,000 for the rest of the summer, MSTU bleeds whether or not MSTR ends the period higher. A reader who wants to engage with this fund should be watching four things, not three, and not the price chart.

• Spot bitcoin and its 30-day realized volatility. Direction matters less than the smoothness of the path. Bitcoin at $61,281.97 off a one-week loss of about 17% is a high-vol regime, which is the worst possible environment for a 2x daily fund.
• Strategy’s premium to bitcoin NAV. The company’s own capital framework gates ATM issuance against mNAV thresholds. When the premium compresses below those gates, issuance slows and the dilution headwind eases. When it expands, the press releases resume.
• STRC’s dividend rate. The variable mechanism is a real-time stress gauge. 11.25% is where it sits now, up from 10.50% announced for November. Further increases would signal continued bitcoin pressure on the credit stack.
• Catalysts on the calendar. Strategy typically discloses bitcoin purchases on Mondays via 8-K, and the Q2 2026 earnings release lands July 30, 2026. The SpaceX IPO on June 12 will compete for the same retail risk dollars that have historically piled into MSTR and MSTU on green days.

Reddit sentiment on MSTR is currently logged as very bearish, with an average sentiment score of 18.89 and threads about Strategy’s first bitcoin sale since 2022 leading the discussion. That is a contrarian setup if bitcoin finds a floor, and an accelerant if it does not. MSTU is the purest expression of that bet in either direction, with one important asterisk. The math of daily reset leverage is structurally negative in chop, and bitcoin’s last month has been nothing but chop. A reader who wants long bitcoin exposure can own bitcoin. A reader who wants long MSTR exposure can own MSTR. The case for owning MSTU instead of either is a case for a smooth, sustained, upward bitcoin tape over a short holding period. That tape is not currently on the screen, and the indicator that would tell you it has arrived is realized volatility.
