You are insane if you think oil prices will stay down and "kill the sector". The downturn in oil is shortterm. In the long run it is not possible for oil prices to stay down. It's simple supply and demand. The worlds demand for oil is going up, driven in part by the China and other developing nations. The demand from China is going through the roof. Presently the world is almost at capacity, we cannot pull it out of the ground faster. Supply and demand, oil is going up, it will be at 100 dollars a barrel in the not to distant future, and probably up from there
Yes it will likely decrease in the short term, but this will be a tremendous buying opportunity for energy stocks. As the momentum investors flee for the exits, there will likely be a significant correction. Energy, however, remains one of the best long-term bets as it will continue to run with the world's ever-increasing appetite for oil.
