KOSPI falls 16.19% in October despite 1.0% GDP growth in Q3

South Korea's economy grew 1.0% quarter-on-quarter in the third quarter, with real GDP up 3.4% year-on-year, according to the Bank of Korea's advance estimate released October 27, yet the KOSPI fell 16.19% in October, dropping 1,107.30 points from 6,838.04 on September 30 to 5,730.74 on October 30, per Korea Exchange data. The divergence between solid growth data and a sharp equity selloff underscores that the October decline cannot be attributed to fundamentals alone, as the GDP figures cover July–September activity while the index move compares end-September and end-October closes. The report showed exports and investment expanding while private consumption lagged, pointing to an uneven recovery. Investors will watch upcoming Bank of Korea policy signals and November trade data to gauge whether the equity weakness reflects positioning, external pressures, or a broader shift in sentiment.
