Stock market today: World shares are mixed as Chinese stocks get a boost from strong factory orders

World shares have started the week mixed, with China leading gains as monthly surveys show improving conditions for manufacturing. Oil prices rose and U.S. futures edged lower. Both official and private sector surveys of factory managers showed strong orders, possibly partly linked to efforts by importers in the U.S. to beat potential tariff hikes by President-elect Donald Trump once he takes office. In a half-day post-Thanksgiving session Friday, the S&P 500 rose 0.6% while the Dow Jones Industrial Average gained 0.4%. The Nasdaq added 0.8%. Some retailers advanced as Black Friday unofficially kicked off the holiday shopping season, although retailers had been offering early deals for weeks. Macy’s and Best Buy each gained around 2%.
