MUU is trading 20.6% down today as traders de-risk leveraged exposure to Micron ahead of its Q3 2026 earnings report scheduled for June 24.

  • As a 2x daily leveraged Micron ETF, MUU is highly sensitive to downside moves in MU and shifting sentiment regarding the memory cycle.
  • The decline tracks a broader tech-led selloff and weaker U.S. equity futures, amplifying losses in the high-beta structure following a significant multi-day rally.
