Cramer's 'Mad Money' Recap: Slim's Pickins

"If you want to piggyback off a winner, Carlos Slim Helu is your guy," Jim Cramer told viewers on his "Mad Money" TV show Thursday.

Slim, he said, is a guy who has made a name buying stocks. "He is the overseas Warren Buffett." In fact, Slim recently surpassed Buffett on the Forbes rich list, which Cramer believes is because of Slim's stock exposure to the rest of the world.

However, people can't just buy whatever Slim buys without doing their own homework, Cramer warned. To pick out what he believes is Slim's best stock, Cramer relied on Stockpickr.com, he said.

He searched the stocks that make up Slim's portfolio on the site and found "the best stock to invest in.

There was some Kraft (KFT) in Slim's portfolio , but Cramer said he's "not a big fan of it."

Another stock in the portfolio was Saks (SKS), but Cramer said he didn't want to highlight this stock again.

Eventually, there was only one stock left for him to push on the show, Cramer said, and it was America Movil (AMX).

It's true that America Movil is at its 52-week high, but the stock was "too good not to feature," he said. The growth of mobile phone service in Latin America has been a great story, and America Movil is the frontrunner of this space in Mexico, Cramer said.
