Comcast Corporation (CMCSA), Prudential Financial Inc (PRU): Here’s What This 1,335% Gainer Has Been Buying and Selling

Valero Energy Corporation (NYSE:VLO) has roughly doubled over the past year, as refiners have been prospering recently. The company is poised to benefit  from the proposed (and controversial) Keystone XL Pipeline, and has been investing in railcars to help bring in crude from inland fields. Some worry about proposed legislation to reduce corn ethanol production, as Valero is a major producer of it, while others worry about a narrowing price gap between foreign and domestic crude.

Finally, Appaloosa Management’s biggest closed positions included Oracle Corporation (NASDAQ:ORCL) and the PowerShares QQQ Trust, Series 1 (ETF) (NASDAQ:QQQ). Other closed positions of interest include Freeport-McMoRan Copper & Gold Inc. (NYSE:FCX). The world’s largest publicly traded copper producer, recently yielding 3.8%, has seen its stock slump in response to a tragic and deadly mine disaster in Indonesia. It had already been hurt by the price of copper falling and growth in China slowing as well as by labor strikes. The company has diversified its operations considerably by buying a pair of oil and gas producers.

We should never blindly copy any investor’s moves, no matter how talented the investor. But it can be useful to keep an eye on what smart folks are doing. 13-F forms can be great places to find intriguing candidates for our portfolios.
