The Shanghai Composite Index lost 0.7% to 3,296.45 while the Nikkei 225 in Tokyo gained 1% to 24,353.15. The Hang Seng in Hong Kong shed 0.2% to 25,649.51. On Wall Street, the S&P 500 rose to 3,510.45. The Dow Jones Industrial Average gained 1.9% to 28,390.18. The Nasdaq composite climbed 2.6% to 11,890.93.
Technology stocks helped power the rally. Rising expectations that Republicans can hold onto the Senate are easing investors' worries that a Democratic-controlled Washington would beef up anti-monopoly laws and go after Big Tech more aggressively.
