Major U.S. stock-indexes lower on Tuesday, dragged down by Apple, as investors worried about China's economic health and braced for an interest rate hike by the Federal Reserve next month. Apple's shares (AAPL) fell 2.5 percent after Credit Suisse said the iPhone maker had lowered component orders by as much as 10%. The stock was the biggest drag on the three major indexes. The report on Apple added to fears of a slowdown in global growth, especially in China, a key market for many U.S. companies including Apple, ahead of the crucial holiday shopping season.
