Stock market today: Asian shares follow Wall Street lower, and Japan reports September exports rose

Shares have tumbled in Asia following a retreat on Wall Street after big U.S. companies delivered mixed profit reports and Treasury yields added pressure on stocks. Worries about war in the Middle East also have been dragging on markets. Benchmarks in Hong Kong, Tokyo and Seoul fell about 2%. Japan reported its exports swung into positive territory in September as vehicle shipments surged. On Wednesday, the S&P 500 fell 1.3% and the Dow Jones Industrial Average shed 1%. The Nasdaq composite fell 1.6%. Crude oil prices fell back after jumping following a deadly explosion at a hospital in the Gaza Strip. Gold prices also were lower. The 10-year Treasury yield touched its highest level since 2007.
