U.S. stock-index futures signaled a weak open on Wall Street on Thursday, after data showed a slowdown in Chinese manufacturing this month.
Chinese stocks closed lower after HSBC's flash PMI (Purchasing Managers' Index) came in at a six-month low of 49.6, down from last month's 50.5.
Frederic Neumann, co-head of Asian economics research at HSBC, said the data indicated problems with China's economy.
"I wouldn't get my hopes up for a big, strong pick-up right after Chinese New Year. Interest rates are rising in China, we know the government is pursuing aggressive reforms; a strong pick-up is not in the cards for China," he added.
