Plunging oil prices drag down Wall Street

Brent crude prices fell to $38.80, while a stronger dollar made it more expensive to hold crude positions. A fall in oil prices erased earlier advances in stock futures that looked to build on Friday's gains after a strong jobs report last week. The solid November employment report showed that the economy was strong enough to absorb an interest rate hike, which is widely expected to be raised when the Federal Reserve meets on Dec. 15-16.
