Crude oil is sliding (USO, WTI, OIL, VDE, IYE, IEO, CVX, OKE, SLB, CHK, CNX, BHI)

Crude oil is extending a slide that began on Friday as OPEC met in Vienna.

At its meeting, the oil cartel decided to set its production level at 31.5 million barrels per day, and did not agree on what the new limit should be. 

On Monday morning in New York, West Texas Intermediate crude futures were down about 4%, and fell to as low as $37.97 per barrel. WTI fell nearly 3% on Friday. In August, WTI hit a year-to-date low of $37.75.

Brent crude was also getting slammed, and fell 3.9% to a six-year low of about $41.31 per barrel. 

After OPEC's meeting, commodity strategists at Goldman put out a note saying that oil prices could plunge another 50% in the coming months, as the oil market tries to rebalance the supply and demand situation.

OPEC members have ramped up production and have exceeded their quota for at least 18 months to try and push out smaller rivals like US shale producers.

Energy stocks were also getting crushed. 

The energy sector was the biggest decliner on the S&P 500 in early trading, and Chevron was down 3%, the most on the Dow.
