Roundup: U.S. stocks slump amid mixed earnings, diving oil

U.S. stocks suffered big losses Tuesday, as oil prices retreated further amid mixed earnings reports.

The Dow Jones Industrial Average slid 295.64 points, or 1.80 percent, to 16,153.54. The S&P 500 tumbled 36.35 points, or 1.87 percent, to 1,903.03. The Nasdaq Composite Index shed 103.42 points, or 2.24 percent, to 4,516.95.

Oil prices continued to plunge Tuesday, with the U.S. oil settling below 30 U.S. dollars a barrel again, as hopes for a deal between OPEC and Russia on output cuts faded away.

The West Texas Intermediate for March delivery moved down 1.74 dollars to settle at 29.88 dollars a barrel on the New York Mercantile Exchange, while Brent crude for April delivery decreased 1.52 dollars to close at 32.72 dollars a barrel on the London ICE Futures Exchange.

With no major economic data due out Tuesday, quarterly results from big companies were in focus.

Alphabet (Class A), Google's parent company, rose 1.32 percent to 780.91 dollars apiece Tuesday, after the company delivered quarterly results above market estimates.

After Monday's closing bell, the tech giant said its adjusted earnings were 8.67 U.S. dollars per share for the fourth quarter of 2015, and revenue also jumped 17.8 percent to 21.3 billion dollars.

Pfizer Inc. edged down 0.10 percent to 30.14 dollars Tuesday after the drug maker posted quarterly results slightly above expectations but guidance for 2016 still shy of forecast.

Latest data from Thomson Reuters showed that the S&P 500 companies' blended earnings in the fourth quarter of 2015 are expected to decrease 4.4 percent year on year, while the revenue is forecast to decline 3.3 percent.

The CBOE Volatility Index, often referred to as Wall Street's fear gauge, rose 10.01 percent to end at 21.98 Tuesday.

In other markets, the U.S. dollar decreased against the euro and Japanese yen on Tuesday as jittery investors favored safe-haven currencies amid plunging oil prices.

In late New York trading, the euro climbed to 1.0909 dollars from 1.0901 dollars in the previous session, while the dollar bought 120.17 Japanese yen, lower than 121.09 yen of the previous session.
