The slide was very consistent all day long as oil hit yet another major snag with news from Iraq that that country's oil output had reached a record high last month.  All three major indexes took a hit of over 1 percent including a 208 point slump in the Dow.  As it has been for some time now and as articulated by today's expert from L.A., "Today is all about oil" as crude fell another two dollars.  At least at 7.9 billion shares, volume was closer to more normal averages of late.  A number of heavyweight Q4 reports are due later this week along with more signals from the Fed regarding future interest rates so eyes will be wide open for awhile.

Wall Street resumes 2016 slide as energy stocks tumble

BY LEWIS KRAUSKOPF

DJ: 15,885.22  -208.29      NAS: 4,518.49  -72.69        S&P: 1,877.08  -29.82

(Reuters)  Wall Street sold off on Monday, pulled lower by further weakness in oil prices as energy shares led declines, with major indexes retreating after last week's strong gains.  Oil prices fell 6 percent on concerns of oversupply after news that Iraq's output reached a record last month.

The S&P energy group .SPNY dropped 4.5 percent, the worst performing sector. Exxon (XOM.N) and Chevron (CVX.N) each fell more than 3 percent, while ConocoPhillips (COP.N) tumbled 9.2 percent after Barclays said the company should cut its dividend by at least 75 percent.

The major indexes each fell more than 1 percent, reversing much of a two-session rally that marked Wall Street's first week of gains in the year. All 10 major S&P sectors finished the session lower.

During the poor start for the year for U.S. stocks, their performance has closely correlated with the price of oil. The commodity's dramatic 1-1/2-year slide has sparked broad concerns about a global economic slowdown.  "Today is all about oil," said Michael James, managing director of equity trading at Wedbush Securities in Los Angeles.

"Better oil markets Thursday and Friday led to better equity markets. A $2 retracement in oil today, it's not surprising to see a retracement in the equity indices."

The Dow Jones industrial average .DJI fell 208.29 points, or 1.29 percent, to 15,885.22, the S&P 500 .SPX lost 29.82 points, or 1.56 percent, to 1,877.08 and the Nasdaq Composite.IXIC dropped 72.69 points, or 1.58 percent, to 4,518.49.

Investors will look for insight about the economy's direction later this week as many heavyweight companies report results. Federal Reserve policymakers meet on Tuesday and Wednesday for the first time since raising interest rates in December.

"The macroeconomic reality is catching up to equity valuations, and you’re seeing folks say, 'I'm going to take my winnings and get out of the way for a while,'" said Jeff Buetow, chief investment officer at Innealta Capital in Austin, Texas.

D.R. Horton (DHI.N) shares fell 4.7 percent to $26.40 as the No. 1 U.S. homebuilder reported lower-than-expected revenue as its home sales fell in all regions but the Southeast.

Tyco International (TYC.N) jumped 11.6 percent to $34.15 after Johnson Controls (JCI.N) said it would merge with the Ireland-based fire protection and security systems maker. Johnson Controls dropped 3.9 percent to $34.21.

Shares of Dynegy (DYN.N) and NRG Energy (NRG.N) slumped 11.5 percent and 9.6 percent, respectively, after the U.S. Supreme Court upheld a major Obama administration electricity markets regulation.

Caterpillar (CAT.N) dropped 5 percent to $57.91 after Goldman Sachs cut its rating on the stock to "sell".

Twitter (TWTR.N) fell 4.6 percent to $17.02 after Chief Executive Jack Dorsey said four senior executives would leave the social media company.

About 7.9 billion shares changed hands on U.S. exchanges, slightly below the 8.1 billion daily average for the past 20 trading days, according to Thomson Reuters data.

Declining issues outnumbered advancing ones on the NYSE by 2,642 to 466, for a 5.67-to-1 ratio on the downside; on the Nasdaq, 2,132 issues fell and 716 advanced for a 2.98-to-1 ratio favoring decliners.

The S&P 500 posted 3 new 52-week highs and 22 new lows; the Nasdaq recorded 12 new highs and 103 new lows.
