The KOSPI index rebounded to the 6920 level after initially starting lower. Despite concerns over rising U.S. long-term Treasury yields, semiconductor stocks surged following Micron's record quarterly earnings, leading to an expansion in the index's gains.
As of 1:33 PM on October 1, the KOSPI was up 85.68 points (1.25%) at 6923.72. The index opened at 6814.49, down 23.55 points (0.34%), but turned positive around 11:20 AM, continuing to rise.
In the securities market, individual and foreign investors sold a net 857.5 billion won and 509.8 billion won, respectively, while institutions bought a net 106 billion won.
Most of the top market capitalization stocks were on the rise, including Samsung Electronics (1.86%), SK Hynix (2.08%), Samsung Electro-Mechanics (2.51%), LG Energy Solution (0.84%), Hyundai Motor (0.43%), and Samsung Biologics (2.52%). However, KB Financial fell by 1.24%.
The KOSDAQ index also showed strength, trading at 882.77, up 26.86 points (3.14%) from the previous day. It opened at 853.96, down 1.95 points (0.23%), but quickly turned positive and maintained its upward trend.

U.S. markets closed mixed overnight, as the August Personal Consumption Expenditures (PCE) price index fell short of market expectations, but long-term Treasury yields surged. However, Micron's record quarterly earnings, which exceeded market forecasts, have raised investor sentiment in the domestic market, particularly in semiconductor stocks.
Micron reported a revenue of $54.23 billion for the fourth quarter of fiscal year 2026 (June to August), surpassing the market estimate of $51.07 billion, according to data from the London Stock Exchange Group (LSEG).
