HONG KONG: European stock markets sank Tuesday while Asian shares mostly rose as investors remained uncertain about the timing of US interest rate hikes and awaited the release of China factory data. KEEPING SCORE European shares were down sharply in early trading. France's CAC 40 lost 1.3 percent to 4,486.91 and Germany's DAX slid 1.7 percent to 9,786.28. Britain's FTSE 100 dropped 1.8 percent to 5,998.98. U.S. stocks were poised to open lower, with Dow futures falling 1.2 percent to 16,254.00. Broader S&P 500 futures shed 1.3 percent to 1,937.20. RATE DEBATE Federal Reserve Bank of Atlanta President Dennis Lockhart on Monday said he was 'confident' of a rate rise this year, echoing weekend comments from other Fed officials. The Fed's decision last week not to raise interest rates sent world stock markets into a slump because the central bank cited concerns about global economic weakness. Lockhart, who said the US economy was 'performing solidly,' joined other Fed officials seeking to reassure investors worried about the state of the global economy. More insight into Fed thinking will come Thursday when Fed chief Janet Yellen delivers a speech. CHINESE FACTORIES Investors were awaiting monthly manufacturing data from China on Wednesday, which will give the latest update on a pillar of the world's No. 2 economy. Caixin's preliminary index based on a survey of factory purchasing managers will be closely watched for any signs of improvement after sinking to a six-year low in August. Fed officials cited China's struggling economy as one factor in its decision to delay hiking rates. QUOTE-WORTHY 'After the Fed held off on its interest rate hike, the next concern is the economic data in mainland China,' said Linus Yip, chief strategist at First Shanghai Securities. 'If it can come out as stabilized and not slowing down, it will be good news. Right now globally, everyone is turning to looking at what's happening in mainland China.'
