Korean retail investors sold $131.01 million more in U.S. stocks than they bought between the 1st and 11th of this month, reversing net purchases in June, July and August. The shift came despite the won strengthening from more than 1,500 won per dollar to around 1,300 won, which reduced currency-conversion costs. Selling centered on SOXL, a triple-leveraged semiconductor ETF, amid geopolitical uncertainty, interest-rate concerns and market volatility, while investors bought short-term Treasury exposure through SGOV and added IonQ and Alphabet. The data was provided by SEIBro, the securities information portal operated by the Korea Securities Depository.
