On June 23, GraniteShares 2x Long MU ETF (MULL) declined 22.48% in regular trading, trading at $839.87/share, with turnover of approximately $149 million. As a 2x leveraged long ETF tracking Micron Technology, the steep decline reflects an amplified move in the underlying stock.

On the news front, South Korean financial regulators have raised alarms over the risks posed by single-stock leveraged ETFs on memory semiconductor companies. The chairman of Korea's Financial Supervisory Service stated on June 22 that negative effects from leveraged ETFs tracking SK Hynix and Samsung Electronics have intensified, and the agency is considering standalone stabilization measures to address the chain risks caused by violent volatility in such products. These concerns extend broadly to leveraged instruments in the memory chip space, where Micron is a major global player.

The regulatory scrutiny highlights growing unease among authorities over retail investor exposure to amplified semiconductor products, potentially dampening appetite for leveraged memory chip instruments across markets.
