On July 21, Direxion Daily MU Bull 2X Shares rose 8.19% overnight, trading at $30.64/share, with turnover of $28.06 million.

On the news front, the memory sector continued its recovery following a sharp selloff triggered by South Korea's Financial Services Commission tightening regulations on single-stock leveraged ETFs, which raised minimum margin requirements from 10 million to 30 million Korean won and restricted collateral to cash only. Underlying stock Micron Technology rose over 4% during the same period, while peer SK Hynix gained more than 5%.

SK Group Chairman Chey Tae-won publicly stated that AI chip demand is expected to surge 60%-100% next year compared to this year, with memory demand growth of 50%-60%. He noted that the supply side has virtually no substantial capacity expansion plans, suggesting the supply-demand gap will continue to widen. As a 2x leveraged ETF, the product's structural characteristics further amplified the rebound magnitude of the underlying asset.
