As the South Korean stock market experienced a sharp decline, Korean individual investors net purchased a total of 315.4 billion Korean won in leveraged products related to Samsung Electronics and SK Hynix between October 1 and 23. This marks the first time this month that individual investors have returned to net buying since regulatory tightening in late July led them to become net sellers. During the same period, Korean investors also net purchased $4.89 billion in U.S. stocks, with the triple-leveraged semiconductor ETF (SOXL) accounting for a significant portion, with net purchases totaling $3.54764 billion, representing 73.9% of the total net purchases in U.S. stocks. Market participants believe that the KOSPI index's cumulative decline of 18.83% in October prompted some retail investors to judge that stock prices were nearing a bottom, leading them to re-enter the market to bet on a rebound.
