Asian stock markets delivered a mixed performance on Thursday as investor sentiment stabilized following the Federal Reserve's decision to keep interest rates unchanged and signs that a recent rout in semiconductor shares was cooling ahead of major U.S. technology earnings reports. Technology-heavy indexes in Japan and South Korea advanced, with the benchmark KOSPI rising more than 4% to around 5,890 and Japan's Nikkei 225 gaining 0.52% to above 62,000, ending a two-session losing streak. Greater China markets remained under pressure, with the Shanghai Composite falling 1.15% to 3,833 and the Shenzhen Component down 1.1% to 13,502, as investors awaited concrete stimulus signals ahead of a Politburo meeting and official PMI data. Hong Kong's Hang Seng Index fell 0.31% to 24,893 after the Hong Kong Monetary Authority held its base rate steady at 4.0% in tandem with the Fed, while India's SENSEX edged up 0.05% to 77,692. Australia's ASX 200 fell 0.84% to 9,019, reversing prior gains, as sentiment was dented by an unexpected spike in second-quarter import prices which surged 5.7% quarter-on-quarter against forecasts for a flat reading.
