[Alpha Biz= Paul Lee] Seoul, November 1, 2025 — South Korea’s benchmark KOSPI recorded its highest daily turnover in four months in October, reflecting increased trading activity among retail investors amid a strong market rally.
According to the Korea Exchange (KRX), the average daily turnover ratio — the value of shares traded as a percentage of total market capitalization — reached 0.57% last month, the highest level since June. A higher turnover ratio indicates more frequent share rotation and active participation among market players.
The surge in trading was largely driven by so-called “big-hand” individual investors, or high-net-worth retail traders managing large portfolios. Between October 1 and 30, the number of large-scale orders (over ₩100 million each) placed by individuals jumped 52% month-on-month, averaging about 28,000 orders per day — the highest since August 2021.
Analysts say the rise in turnover underscores renewed retail confidence in Korean equities following the KOSPI’s autumn rebound, fueled by expectations of lower interest rates and strong corporate earnings in the semiconductor and technology sectors.
