On July 7, Direxion Daily MU Bull 2X Shares declined 5.26% overnight, trading at 725.0 USD/share, with turnover of 1.5745 million USD. The ETF gave back gains from the prior session's technical rebound, as bearish forces reasserted dominance.

On the news front, the decline was driven by renewed short-selling pressure and persistent AI infrastructure overcapacity concerns. Notable investor Michael Burry recently established a short position in underlying stock Micron Technology at $1,051.87 per share, warning that the stock's cyclical peak has surpassed internet-bubble-era levels. Additionally, earlier reports of Meta planning to sell surplus AI computing capacity continued to fuel fears of industry-wide overcapacity in high-performance memory chips.

The prior session's rally, triggered by Micron's $9.3 billion Hiroshima advanced memory fab groundbreaking, was widely characterized as a technical rebound from oversold conditions. With Micron's stock still down over 20% from its post-earnings high, the underlying downtrend remains intact, and the ETF's 2x leverage further amplified the pullback.
