Analysis:Korean 'ants' swarm back to Wall Street as KOSPI rout dents homecoming drive

South Korean retail investors are returning to U.S. stock markets as Seoul's KOSPI stock index experiences a significant decline, reversing a government-backed push to attract homegrown investors. In July, retail investors poured $4.6 billion into U.S. stocks, surpassing the $2.7 billion monthly average seen in 2025. Analysts cite the KOSPI's sharp decline, down 33% from its June peak, as a major factor driving this shift, with chipmakers Samsung Electronics and SK Hynix bearing much of the market's value loss.

The stronger won, up 8% in July, further dampens incentives to repatriate foreign assets, potentially leading to more foreign investments in U.S. stocks.
