Overnight, stocks lost momentum on Wall Street as investors tuned in to a news conference by Federal Reserve Chairman Jerome Powell. Speaking to reporters Wednesday afternoon, Powell acknowledged that there's a risk the outbreak could slow the global economy. But stocks barely budged after the Fed announced would leave its benchmark interest rate unchanged at a low level. The move, which was widely expected, reflects the central bank's mostly positive view of the U.S. economy.
Last year, the Fed cut its benchmark interest rate three times after having raised it four times in 2018. Powell credits those rate cuts with revitalizing the housing market, which had stumbled early last year, and offsetting some of the drag from President Donald Trump's trade war with China.
