May 3 (Reuters) - Wall Street opened lower on Tuesday as weak Chinese economic data and a surprise rate cut by the Australian central bank fanned worries about the health of the global economy.
Activity at China’s factories shrank for the 14th straight month in April as demand stagnated, a private survey showed.
Australia’s central bank also sprang a surprise by cutting interest rates to a record low of 1.75 percent, the first easing in a year as it seeks to restrain a rising currency and insulate the economy from creeping deflation.
“The negative news out of China and Australia having to stimulate its economy again is spooking the market today,” said Peter Cardillo, chief market economist at First Standard Financial in New York.
“The market is in the midst of a pullback and nervous about lower growth, which might mean weaker earnings in the coming quarters.”
