The Great Reversal: Korean Retail Investors Pile into Leveraged ETFs on Market Plunge

The trading activity of Korean retail investors took a sharp and unexpected turn last week. After three consecutive days of net selling, they staged a massive counter-trend move on one of the market's worst days.

A Data-Driven Plot Twist

Data from the Korea Exchange and Koscom Check shows a clear pattern: from July 21 to 23, individual investors were net sellers of 14 single-stock leveraged products, offloading a total of about ₩547.2 billion. The narrative flipped completely on July 24.

That day, the KOSPI index plummeted more than 5%. Shares of bellwethers Samsung Electronics and SK Hynix fell 7-8% at the close. The single-stock leveraged ETFs tracking them crashed even harder, down 15-16%.

Where Did the ₩450 Billion Go?

Amid the broad sell-off, retail money flooded in. On that single day, July 24:

  • They were net buyers of 7 Samsung Electronics single-stock leveraged products, purchasing approximately ₩103.9 billion worth.
  • They were net buyers of 7 SK Hynix single-stock leveraged products, with net buying reaching a massive ₩350 billion.

The combined net buying amounted to nearly ₩450 billion, almost erasing the net selling of the prior three days.

The Dual Drivers: Bargain Hunting and Regulatory Rush

Market analysts point to a mix of motivations behind this concentrated buying spree.

The first is straightforward bargain hunting. The exaggerated decline in leveraged ETFs presented a high-risk, high-reward entry point for investors comfortable with volatility.

The second, and potentially more urgent factor, is an impending regulatory shift. New rules set to take effect on July 31 will raise the minimum margin requirements for trading these single-stock leveraged products. This will effectively reduce the amount of leverage available for the same capital.

Consequently, some investors likely aimed to establish or increase their positions under the current, more favorable margin terms before the window closes. This "front-running" of regulatory changes is a common dynamic in such transition periods.

This episode underscores the sophisticated and reactive nature of Korea's active retail trading community. They are adept users of leveraged instruments, highly responsive to market swings, and quick to adjust strategies based on the regulatory landscape. Their collective actions remain a significant force shaping liquidity and demand for specific financial products.
