Kospi Nears 7,000, but Retail Investors Ramp Up Downside Bets

Retail traders show stronger appetite for short-term trades than for following the rally

The Kospi has rebounded sharply and is nearing the 7,000 mark, yet retail investors have continued to lock in profits. Instead, they have been buying inverse products that profit from a decline in the benchmark, signaling they are putting more weight on a pullback than on further gains. Short-selling balances tied to bearish bets have also increased this month. The pattern suggests the Kospi may need more time to dispel concerns over lofty valuations and restore investor confidence.

Data from ETF Check, Koscom’s ETF data platform, showed the exchange-traded fund most heavily bought by retail investors over the past week was KODEX 200 Futures Inverse 2X, which tracks minus two times the daily return of the Kospi 200 futures index. Net purchases totaled 132.8 billion won. Other top retail buys included products positioned for declines, including KODEX Inverse, ranked third, and SOL SK Hynix Futures Single Stock Inverse 2X, ranked ninth.

The buying suggests retail investors still see a higher chance of a drop in the Kospi. The index slid to the 5,300 level after a sharp correction last month, but has rebounded this month and is now on the verge of reclaiming 7,000. With the Kospi rising about 10% in the past week alone, individual investors appear to be bracing for a correction rather than chasing further upside.

EpicAI, an artificial intelligence-based investment information platform, said South Korean retail investors were net sellers on the Kospi for four straight trading days from Aug. 11 through Aug. 14. They sold a combined 7.984 trillion won over the four sessions. Selling continued even as the Kospi climbed from 6,345.53 on Aug. 11 to 6,977.94 on Aug. 14. Foreign investors, by contrast, were net buyers for four straight sessions over the same period, absorbing shares offloaded by retail traders.

Investor deposits, often viewed as standby funds for the domestic stock market, are also shrinking. According to the Korea Financial Investment Association, investor deposits stood at 139.6948 trillion won as of June 4. By Aug. 13, they had fallen to 100 trillion won. That means roughly 40 trillion won left in a little more than two months, suggesting investors are gradually stepping back from equities.

Retail investors had already shown signs of shifting toward U.S. stocks during the Kospi’s sharp selloff. Over the past month, the ETF with the largest net retail inflow was TIGER U.S. S&P 500, which drew 631 billion won. KODEX U.S. Nasdaq 100, at 443.7 billion won, and KODEX U.S. S&P 500, at 348.2 billion won, were also among the top net buys.

Retail flow is increasingly geared toward short-term trading rather than trend-following, according to Lee Jae-won, an analyst at Yuanta Securities. Since July 31, foreigners have repeatedly bought on strong up days while individuals sold, and sold on sharp down days while individuals bought, he said. In Lee’s view, retail trading has shifted from chasing trends to buying on dips during corrections and taking profits during rebounds.

Short-selling balances are also rising. As of Aug. 11, the net short balance on the Kospi stood at 19.006 trillion won. That was up 2.272 trillion won from 16.734 trillion won at the end of last month. Short selling involves borrowing shares, selling them and then buying them back before the due date to return them, profiting from selling high and repurchasing at lower prices. In other words, even after the Kospi rebounded from the 5,500 level at the end of last month to the 6,300 level by Aug. 11, investors were still positioning for a decline.
