Japan's Nikkei Stock Average fell by 0.66% to close at 38,110.22, primarily influenced by a strengthening yen that has raised concerns about export margins for Japanese companies, particularly in the semiconductor and automotive sectors. The decline was exacerbated by investor caution ahead of Nvidia's upcoming earnings report, which is anticipated to significantly impact market sentiment. Notable losses were seen in chip-related stocks such as Tokyo Electron and Advantest, with declines of 2.51% and 2.43%, respectively. The broader Topix index also fell, down 0.87% to 2,661.41, largely attributed to a 2.87% drop in the automotive sector, with Toyota Motor Corp leading the losses. Analysts suggest that the yen's rise, spurred by speculation of a potential U.S. Federal Reserve interest rate cut, reflects a policy divergence between the Fed and the Bank of Japan. As a result, Japan's stock market is navigating through volatility with mixed investor sentiment and a cautious outlook for exporters.
