An employee is working in the dealing room of Hana Bank in Jung-gu, Seoul on the 15th. Yonhap News KOSPI index rose more than 6% on the 15th and recovered to the 7,000 level. The reason for the rise was the revival of investment sentiment, especially in semiconductor stocks such as Samsung Electronics and SK Hynix, which had been weak so far. The securities industry believes that the performance announcements of big tech companies scheduled for the end of this month will be a key variable that will determine the direction of the domestic stock market.
