Following OPEC's decision at the end of November to maintain production at its current level, the Brent spot price of oil closed at $70.02 per barrel, down 39 percent from its closing price of $115.19 on June 19, 2014. Similarly, the WTI spot price fell by 39 percent over the same period, closing at $66.15 at the end of November. What's next? Will the price of oil continue to fall, and if so, how far? Will the price of oil level out? Or will it rebound?
