At Money Morning over the past six months, we’ve talked a great deal about oil and gasoline prices. We’ve offered our predictions about how high those prices were going, and have detailed a number of investment opportunities - chosen as much for their margins of safety as for their profit potential.

This time we’re going to detail three energy stocks with the potential for double-digit - or even triple-digit - profit gains. Admittedly, these are longer-shot, speculative plays. But we used a special energy indicator to help ferret out these energy plays.

UPDATE 4-Valero earnings tumble but handily beat Wall St

  
 Jan 28 (Reuters) - Credit Suisse upgraded U.S. independent 
 refiners to "neutral" from "underweight," saying the sector 
 looks more sensibly priced than it has for several months. 

  The brokerage said it compared current price-to-earnings 
 multiples under several economic scenarios against the recent 
 historic levels and concluded that the refining sector is now 
 pricing in at least a mild U.S. recession case.
