if you held Direxion Daily MU Bull Stock 2X (NYSEARCA:MUU) through Friday’s close, saw the fund lose 26.65% in a single session, which is what 2x daily leverage does when its underlying has its worst day in years. The underlying Micron technology (NASDAQ:MU), closed at $864 on June 5, 2026, down approximately 13% from a previous close of $996. A move of about 13% in the stock that becomes about 27% in the bottom line is the textbook result of a clean one-day drop, with no need for a volatility brake. The interesting question is what happened to MU. The fund did exactly what it was designed to do.

The Arithmetic of Leveraged Relaxation

Before Friday, MU was the poster child for the chip cycle. Shares were still up 203% so far this year through June 5 and 715% in the trailing twelve months, in an HBM (high-bandwidth memory) supercycle that the company was telling investors extended to multi-year contracts through fiscal 2026. Micron’s market capitalization stood at $974.37 billion after Friday’s drop, and the CEO Sanjay Mehrotra had raised guidance just two quarters earlier to $18.7 billion in revenue plus or minus $400 million for the fiscal second quarter of 2026, along with non-GAAP gross margin guidance of 68.0%. The Q1 report itself showed $13.64 billion in revenue (up 57% year-over-year) and earnings per share (EPS) of $4.78 versus a consensus of $3.94. None of that fundamental picture changed on Friday. The price changed.

For MUU holders, the math is brutal in both directions. The fund resets daily, so a stock that rises day after day drags down the leveraged vehicle at a rate that more than doubles cumulatively. The same arithmetic in reverse, a single concentrated drop, gives you exactly Friday. A loss of about 13% in MU produced a loss of about 27% in MUU, almost linear. There is no need to invoke volatility for a bad day. The drag comes later, in the cut that usually follows a violent movement like this.

What really triggered the liquidation?

The crash began Wednesday night, two days before MU was attacked. Broadcom (NASDAQ:AVGO) reported after the close and guided third-quarter AI semiconductor revenue to about $16 billion, versus an unofficial buy figure closer to $17.2 billion, an error of about 7%. CEO Hock Tan added a comment that Google may use multiple chip suppliers, which the market interpreted as a small but real notch away from the hyperscaler concentration thesis. AVGO fell about 20% between June 3 and June 5, including a drop of almost 8% on Friday alone.
