On July 15, Direxion Daily MU Bull 2X Shares (MUU) declined 5.07% in regular trading, trading at $35.10/share, with turnover of $107 million.

On the news front, the Korea Financial Investment Association convened an emergency meeting with major brokerage CEOs, where participants agreed in principle to tighten investor protection regulations for single-stock leveraged ETFs. Proposed measures include raising the minimum margin threshold from 10 million won to 50 million won, strengthening targeted risk disclosures and investor education, and distributing rebalancing trades across multiple intraday time slots to reduce end-of-day market impact.

While the regulatory changes primarily target the Korean market, they have dampened global investor risk appetite for leveraged ETF products. As a 2x leveraged ETF tracking Micron Technology, MUU is inherently sensitive to shifts in sentiment surrounding leveraged instruments. The ETF had previously rebounded over 11% in the prior session following an oversold bounce in the storage sector, making it particularly vulnerable to renewed selling pressure triggered by the regulatory headline.
