South Korean stocks extended their rebound on Thursday, with the KOSPI rising nearly 4% to around 6,830, reaching its highest level in almost three weeks and staying roughly 23% above its July 30 low, a move that keeps the benchmark in technical bull market territory. Samsung Electronics climbed more than 4% and SK Hynix surged over 7% as an overnight rise in U.S. technology shares and renewed optimism over AI-related demand lifted sentiment across memory-chip makers. Gains also spread to SK Square, Hyundai Motor, LG Energy Solution, Hanwha Aerospace, HD Hyundai Heavy Industries and Kia Corporation. The rally was reinforced by a softer-than-expected U.S. inflation reading that reduced expectations for a September Federal Reserve rate hike, improving risk appetite for technology shares. South Korea's plan to ease regulations for semiconductor and AI megaprojects, which the government expects to generate KRW 4.2 trillion in investment, added domestic support. Fundstrat Global Advisors has said a breakout in the iShares MSCI South Korea ETF and improving performance in memory shares point to further near-term upside, while warning that higher U.S. Treasury yields and a stronger dollar could still challenge momentum.
