ISM manufacturing dents stocks to start off first quarter

Stocks fell after the Institute for Supply Management said U.S. manufacturing activity fell last month to its lowest level in a decade as the U.S.-China trade worries drag on. The ISM report follows the release of weak manufacturing data from Europe. The disappointing numbers led investors to sell equities in favor of U.S. bonds.
