Cramer's 'Stop Trading!': Buy Oil Stocks

"I think oil has bottomed. I think we should be buying oil stocks," said Jim Cramer on Wednesday's "Stop Trading!" segment on CNBC. "The multiples are the lowest I've seen, and if oil stays in the $40s, these companies are going to make a lot of money."

He specifically recommended Exxon(XOM Quote), ConocoPhillips(COP Quote), Terex(TEX Quote) and Occidental(OXY Quote). "I want that dividend," he said.

Copper inventories "have been going down, down, down, down, down," Cramer said. "I believe that this is a sign that the Chinese stimulus is working. He said that Freeport-McMoRan(FCX Quote) "is ramping, and I don't think it's done."

Caterpillar(CAT Quote) is experiencing a "big short-cover rally," Cramer said. That said, "You can't build roads and bridges without CAT, so maybe the money is going to start trickling down."

Cramer said that people "confuse BJ's(BJ Quote) with Costco(COST Quote)." Whereas Costco sells avoidable products such as electronics and jewelry, BJ's "is much more staple, staple, staple." Costumers at BJ's and Big Lots(BIG Quote) can "buy cheaper products and more of them."

Last night, Cramer said, Aecom(ACM Quote) "did a secondary at $20, and if you bought it, you're up a buck. When is the last time that happened?" He said it's an "extra signal that there's demand."
