Mad Money Lightning Round: Cramer Likes Aruba Networks

On CNBC's Mad Money, Jim Cramer said during the Lightning Round that Aruba Networks (NASDAQ: ARUN) is a “good Internet commerce play."

For Goldman Sachs (NYSE: GS), he said, "I'm not going to recommend any financials on this show. It's like taking your life in your own hands."

Cramer said that Stamps.com (NASDAQ: STMP) could “go down but I like what they're doing."

For Cummins (NYSE: CMI), he said, "I'm willing to take the pain for a big 2012."

Jim said that AT&T (NYSE: T) is a “win-win either way on the T-Mobile deal. I've been buying it for my trust."

For McMoran Exploration (NYSE: MMR), he said, "I've got high quality companies going down, so I'm not going to recommend a speculative one."

Cramer said, “The mineral companies, like Teck Cominco (NYSE: TCK), have gone out of favor.” He added, “It's not bad, but it's not going to work here. It's going to go down." For Gold Resource (AMEX: GORO), he said, "I think gold is under liquidation. You need to wait a few days. Give it a breather. I still like gold."
