TheStreet.com's Jim Cramer says eventually, the credit markets will thaw, and this one will take off like a rocket.

Cheap isn't always relative. Consider the case of Shaw Group (NYSE: SGR) (Cramer's Take), the infrastructure play with the nuclear bent that has tons of business around the world building nuke plants that are competitive with oil and nat gas even at these prices, but obviously are much better for the environment.

Shaw's doing great -- big order book, no cancellations or stretch-outs (unlike ABB (NYSE: ABB) (Cramer's Take) or McDermott (NYSE: MDR) (Cramer's Take)), and most important, its stock is trading a mere dollar and a half above its cash.

It's absurd, as the CEO told me last night on a pre-empted edition of the 6 p.m. "Mad Money." The valuation makes no sense.

TheStreet.com's Jim Cramer says this report highlighted where the success lies in this market: energy and petroleum.

Fluor's (NYSE: FLR) (Cramer's Take) a monster. It shows you that what has hurt the other companies, particularly Chicago Bridge & Iron (NYSE: CBI) (Cramer's Take), is pure execution.

This gigantic beat also serves to remind us of the big dichotomy. You are either in the energy and petroleum products game or you are in a lot of games that don't work.

It's not easy for these companies, some of which have lived off the duress of state and local governments, including Shaw (NYSE: SGR) (Cramer's Take) and to a certain extent Aecom (NYSE: ACM) (Cramer's Take) and URS (NYSE: URS) (Cramer's Take), to become oil-and-gas plays.

The only ones that have transcended it beside Fluor are Foster Wheeler (NASDAQ: FWLT) (Cramer's Take) and Jacobs Engineering (NYSE: JEC) (Cramer's Take), and the only reason you would really know that is longevity. I remember in the early 1980s when FLR and then FWC would compete directly for all of the huge projects after the second oil shock.
