On CAPS, 96% of the 4,517 members who have rated Valero believe the stock will outperform the S&P 500 going forward. These bulls include All-Star Itemirus and nuf2bdangrus.

Just two weeks ago, Itemirus tapped the stock as a cheap way to gas up: 

Valero is way oversold - the company is trading at around half book value, has manageable debt and is sitting on a billion dollar cash pile - moreover, it is owning significant ethanol producing assets - i am positive we will see her recover above $20 in a few months.

In a pitch from last month, nuf2bdangrus cracked the bull case even wider:

Despite the bad crack spread which affects refiner margins, they are trading as if there will be no recovery while the consumer stocks trade as if recovery is a sure thing. The truth lies somewhere in the middle, but failing to buy refiners at these cheap prices is a mistake you shouldn't make. … Moreover, [Valero] can refine types of crude other refiners can't, and when an external shock hits the oil markets, I think US refiners will benefit. Finally, when refiners as a group are trading at or near book value, the prospects of a takeover by an integrated oil company can't be ruled out.
