Market analysts noted that despite weakness in the semiconductor sector, a rotation of investments flowed into KOSDAQ. Lim Jeong-eun, a researcher at KB Securities, stated, "Reports of OpenAI delaying its IPO and concerns over reduced memory demand due to Apple's price hikes led to a decline in tech stocks in the U.S. market, which also affected the domestic market, particularly in the semiconductor sector."
She added, "After an 11% drop last week, KOSDAQ rebounded strongly, driven by rotations in the bio and secondary battery sectors, with the percentage of rising stocks reaching 86.07%, the highest since March 5 of this year."
Lim also pointed out that ongoing issues related to semiconductor supply, including Apple's consideration of sourcing memory from China, along with key macroeconomic events such as the U.S. non-farm payrolls for June, warrant caution regarding market volatility this week.
Meanwhile, in the Seoul foreign exchange market, the won-dollar exchange rate closed at 1,545.2 won, up 13.2 won from the previous trading day.
