On November 6, the domestic stock market closed mixed. The KOSPI, which had started the session with a rise of over 2%, turned downward during the day and at one point fell below the 4,000 mark. However, buying from individual and institutional investors helped the index recover and maintain the 4,000 level for a second consecutive day.
