On July 7, Direxion Daily MU Bull 2X Shares (MUU) fell 11.95% in regular trading, trading at approximately $670.50/share, with turnover of $507 million.

The decline was driven by multiple converging headwinds on underlying stock Micron Technology. Samsung Electronics reported Q2 operating profit surging 1810% year-over-year to 89.4 trillion won, but the blockbuster result paradoxically triggered market concerns over intensifying industry competition and potential supply-demand imbalance, sending Samsung shares down nearly 7% in Korea and dragging global memory stocks lower. Micron fell approximately 5.9% intraday, with the ETF's 2x leverage amplifying the loss.

The sell-off erased gains from the prior session's technical bounce, which was fueled by Micron's $9.3 billion Hiroshima HBM factory groundbreaking. Market participants broadly characterized that rally as merely an oversold recovery. Renowned investor Michael Burry's short position initiated at $1,051.87, combined with lingering AI overcapacity fears stemming from Meta's plan to sell idle computing capacity, continued to weigh on sentiment. Micron executive April Arnzen's $43.4 million share sale further intensified concerns.
