The price of oil sank by more than $2 a barrel Thursday, settling at its lowest level in a year as traders focused on the bearish aspects of conflicting market trends. OPEC is cutting output, but the U.S. economy is slowing; winter is near, but the country has an abundance of home heating fuels.
As the story says, oil is at a new low for the year, which for me is a big surprise. I have been expecting a rise and if and when OPEC decides to make further cuts then oil should rise.
