On CAPS, 96% of the 4,523 members who have rated Valero believe the stock will outperform the S&P 500 going forward.

Just last week, one of those Fools, All-Star BudandMolly, succinctly summed up the Valero bull case for our community:

Refiners have a monopoly on gas production. Due to regulation there is a virtual block to any new refineries or even expansion of existing ones leaving them without competition. Limited production of gasoline keeps prices high and as oil prices come down due to domestic production increases the spread of input costs to output prices increases.
