The 2x Micron ETF (MUU) Shed 26.65% in One Day When Broadcom Missed and Rates Spiked

MUU shed 27% in a single session as MU dropped 13%, despite the stock still sitting 203% higher year to date.

Broadcom's AI revenue guide missed buyside expectations by 7% and sent AVGO down 20%, while NVDA fell only 6% on Friday.

Micron's June 24 earnings are the binary event. Soft HBM pricing confirms a cycle break, while a clean beat reverses MUU's damage.

If you held Direxion Daily MU Bull 2X Shares ( NYSEARCA:MUU ) into Friday's close, you watched the fund shed 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 roughly 13% from a prior close of $996. A roughly 13% move in the stock turning into roughly 27% in the fund is the textbook outcome on a clean one-day drop, no volatility drag required. The interesting question is what happened to MU. The fund did exactly what it is engineered to do.

Before Friday, MU was the chip cycle's poster child. The stock was still up 203% year to date through June 5 and 715% over the prior twelve months, riding an HBM (high-bandwidth memory) supercycle that the company was telling investors stretched into multi-year contracts through fiscal 2026. Micron's market capitalization sat at $974.37B after the Friday drop, with CEO Sanjay Mehrotra having raised guidance just two quarters earlier to $18.70B in revenue plus or minus $400M for fiscal Q2 2026, alongside a non-GAAP gross margin guide of 68.0%. The Q1 report itself delivered $13.64B in revenue (up 57% year over year) and EPS of $4.78 versus a $3.94 consensus. 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 compounds higher day after day drags the leveraged vehicle along at a rate that exceeds 2x cumulatively. The same arithmetic in reverse, a single concentrated drop, gives you exactly Friday. A roughly 13% loss on MU produced a roughly 27% loss on MUU, almost linear. There is no need to invoke volatility drag for one bad day. The drag arrives later, in the chop that tends to follow a violent move like this one.

The crack started on Wednesday night, two days before MU got hit. Broadcom ( NASDAQ:AVGO ) reported after the close and guided Q3 AI semiconductor revenue to roughly $16.0B against an unofficial buyside number closer to $17.2B, a miss of about 7%. CEO Hock Tan added commentary that Google may use multiple chip suppliers, which the market read as a small but real notch out of the hyperscaler concentration thesis. AVGO fell roughly 20% over June 3 to June 5, including a nearly 8% drop on Friday alone.
