On July 13, Direxion Daily MU Bull 2X Shares (MUU) fell 12.5% in pre-market trading to $648.5/share, with turnover of $22.86 million.

On the news front, the world's three largest memory chipmakers have collectively announced aggressive capacity expansion plans. Samsung and SK Hynix committed a combined $880 billion in investment, while Micron Technology unveiled a $250 billion domestic investment plan through 2035, triggering deep market concerns over medium-to-long-term overcapacity in the storage chip sector.

The underlying stock Micron Technology fell approximately 5.9% in pre-market trading, having now declined over 26% from its high of $1,255, firmly in technical bear market territory. SK Hynix's Nasdaq ADR debut on July 10 — raising $26.5 billion in the largest-ever foreign company U.S. listing — continues to divert sector capital. Additionally, noted short seller Michael Burry's short position on Micron, established near $1,051.87, remains open, intensifying bearish sentiment. As a 2x leveraged ETF, the inherent leverage effect further amplified the drawdown magnitude.
