On July 21, Direxion Daily MU Bull 2X ETF rose 10.24% in pre-market trading, trading at approximately $31.63/share, with turnover of $19.84 million.

On the news front, the memory chip sector extended its recovery following a sharp selloff triggered by South Korea's Financial Services Commission tightening regulations on single-stock leveraged ETFs. Underlying stock Micron Technology gained over 4% in the same period, while peer SK Hynix rose more than 5%. SK Group Chairman Choi Tae-won publicly stated that AI chip demand is expected to surge 60%-100% next year compared to this year, with memory demand growth reaching 50%-60%, while the supply side has virtually no substantive capacity expansion plans, suggesting the supply-demand gap will continue to widen. KeyBanc analysts echoed a bullish stance, forecasting DRAM and NAND prices to rise through the coming quarters with supply tightness persisting through at least 2028, maintaining an Overweight rating on Micron with a $1,750 target. As a 2x leveraged product, the ETF's structural characteristics further amplified the underlying rebound magnitude.
