On July 8, Direxion Daily MU Bull 2X Shares declined 5.18% in after-hours trading, trading at $652.0/share, with turnover of $29.84 million.

On the news front, the decline was primarily driven by persistent short-selling pressure and unresolved AI overcapacity concerns weighing on its underlying stock, Micron Technology. Micron has fallen over 20% from its post-earnings high, a downtrend that remains intact, with the ETF's 2x leverage further amplifying losses.

The ETF had previously rebounded sharply after Micron announced the groundbreaking of a $9.3 billion advanced memory chip expansion in Hiroshima, Japan, focused on producing high-bandwidth memory for AI processors with expected shipments starting in summer 2028. However, the market broadly characterized that rally as a technical recovery from oversold conditions. Notable investor Michael Burry previously established a short position in Micron at $1,051.87, warning its cyclical peak exceeded internet bubble levels. Additionally, Meta's plans to sell idle AI computing capacity have fueled ongoing overcapacity fears across the sector, reinforcing bearish sentiment.
