Most U.S. Stocks Fall as Apple Slump Tempers Dell’s Rally

Most U.S. stocks fell, after a two- week gain in the Standard & Poor’s 500 Index, as a slump in Apple (AAPL) Inc. tempered Dell Inc. (DELL)’s rally on buyout talks.

Apple, the most valuable company, sank 3.8 percent on reports it curbed iPhone production on weak demand. Dell surged 13 percent as two people with knowledge of the matter said the company is in discussions with private-equity firms.
