Are Oil Prices and ETFs On a Slippery Slope?

The price of oil took a step back on Monday, causing its related exchange traded funds (ETFs) to head south along with it.

John Wilen for the Associated Press reports that oil dropped $4.17 to $106.04 a barrel after hitting a high of $111.80. The price of diesel fuel rose to a new record, above $4 a gallon, and the price of a gallon of gas stayed high.

Some analysts are saying the oil is in a bubble – especially since the price keeps rising, but demand growth predictions have been lowered and supplies are higher.

Oil ETFs were down in trading today. Will there be a rebound, or are investors beginning to get skittish?
