BALTIMORE ( Stockpickr) -- 2013 is turning out to be a pretty good year for Warren Buffett. Year-to-date, the octogenarian billionaire has seen his firm, Berkshire Hathaway ( BRK.A, BRK.B), rally more than 25.6%. That's almost double the returns that investors have gotten from the broad market over that same period.

The Oracle of Omaha hosted Berkshire Hathaway's annual shareholder meeting earlier this month, where he was grilled on stage by TheStreet's own Doug Kass.It's a little bit misleading to put all of the investment focus on Buffett; former hedge fund managers Todd Combs and Ted Weschler have a major role in selecting the stocks that make up Berkshire's portfolio. But considering the fact that both managers beat the S&P 500 by double digits last year, Buffett's hand-picked successors are worth listening to. >>5 Stocks the Smart Money Hates -- But Should You?

But even though the buying has been cautious, it tells us a whole lot more about the stocks that these guys like than if they'd been buying with both hands. Today, we'll focus on five names that are either newly initiated positions or position increases for Warren Buffett's portfolio at Berkshire Hathaway. >>5 Stocks Setting Up to Break Out
