I think Valero owns some retail operations, natural gas, and pipelines in addition to the refining capacity.
If you are a Benjamin Graham disciple, I believe he said that the long-term historical PE for the overall market is about 7, and anything above that is speculative. So with a PE of 28 or whatever, the SP500 is about four times overvalued based on its long term historical average.
The doomers will get a charge out of this. It suggests that the market could easily go down by 75% to be "fairly valued".
These refiners are cheap, because their "growth rate" has been historically low. I think their shrinkage rate is low too.
In 1982, Texaco was earning $8 per share, this was in the absolute height of the big recession. Today, as part of Chevron/Texaco, they are earning $7 per share, in modern-day dollars.

For those fellow posters who have started to yawn on this, all of this has a bearing on the oil price and the availability of gas for your car. If the refiners have a PE of 8, and Google has a PE of 40, Google is going to find it easier to raise cash to expand their business. The refiners have to go into the same credit market and get money for their expansion projects and compete with the Googles of the world for money. If the project is not attractive enough, or too risky, Google will get the money.
The same goes for exploration and drilling, even more so because of the risk.
Ironically, if the housing thing really does move up the food chain and get into the realm of "prime" rather than just be confined to sub=prime, a lot of these potential energy projects are going to be impacted because no one can afford to finance them. This will make some of these so-called "advanced drilling" projects not viable from a business standpoint until the oil price gets high enough to justify the risk.
