South Korea approved 16 single-stock leveraged ETFs at the end of May. Within weeks, regulators were already calling the decision “hasty.”

The products, which offer 2x daily exposure to Samsung Electronics and SK Hynix, launched on May 27 with roughly $3 billion in assets. By June, that figure had ballooned to approximately 14 trillion won ($9.1 billion). Retail investors hold 92% of those combined assets.
