With all the commotion surrounding energy these days, it never hurts to track an energy focused hedge fund ran by none other than T. Boone Pickens. If you are unfamiliar with Pickens, he is an energy maverick and his fund returned 300% in 2005. He is a big advocate of Peak Oil Theory and runs an energy-centric hedge fund based in Dallas, Texas. Although he typically holds numerous positions in oil, he is also big on alternative energy (except ethanol) and has numerous holdings there as well. He most recently advocated a large natural gas position and has additionally made a big bet on wind energy.
