US stocks tumble amid skepticism of Fed rate cuts

Wall Street stocks finished sharply lower Tuesday, reflecting skepticism at a surprise Federal Reserve interest rate cut while the 10-year US Treasury hit an all-time low.

The Dow Jones Industrial Average ended at 25,917.41, down 2.9 percent, a loss of nearly 800 points.

The broad-based S&P 500 sank 2.8 percent to finish the day at 3,003.37, while the tech-rich Nasdaq Composite Index slid 3.0 percent to 8,684.09.

The pullback came a day after a major stock rally and pushed the market back towards last week's sentiment, when coronavirus worries led to major indices suffering their worst weekly losses since 2008.

Across the world, 3,155 people have died from the virus. More than 92,723 have been infected in 78 countries and territories.

In a surprise move, the Fed slashed its key interest rate by a half point to a range of 1.0-1.25, a bigger cut than usual.

While US economic fundamentals "remain strong," the "coronavirus poses evolving risks to economic activity," the Federal Open Market Committee said in a statement.

Stocks initially rallied on the Fed announcement, but soon pulled back.

"The Fed's emergency rate cut was supposed to boost confidence but it may wind up raising fears that the coronavirus is likely to cause a major economic downturn," economist Joel Naroff said.

Briefing.com analyst Patrick O'Hare said the Fed's action "could ultimately erode market psychology because when you act that quickly, that aggressively in that short amount of time, it does raise a concern that things are going to get potentially must worse than what was presumed."
