On July 17, Direxion Daily MU Bull 2X ETF declined 9.85% in pre-market trading, trading at $25.02/share, with turnover of $27.48 million.

On the news front, South Korea's Financial Services Commission officially announced tightened regulatory measures targeting single-stock leveraged ETFs, including raising the minimum margin requirement from 10 million KRW to 30 million KRW, accepting only cash as eligible collateral, capping single-stock leveraged trades at 20 shares per order, and banning new single-stock leveraged product listings. The measures precisely target one of the most active speculative funding sources in memory chip trading.

The regulatory crackdown triggered SK Hynix to plunge over 11% on the Korean exchange, with chain reactions rapidly transmitting to the US memory sector. The underlying stock Micron Technology fell over 5% in pre-market trading, with its market capitalization slipping below the one-trillion-dollar mark. As a 2x leveraged ETF, its product structure further amplified the magnitude of the underlying asset's decline, resulting in a near-10% pre-market drop.
