The 44-stock, $303 billion portfolio the Oracle of Omaha oversees at Berkshire Hathaway has two amazing deals hiding in plain sight, as well as a pricey brand-name stock worth steering clear of.

Buffett invested in Heinz in 2013 and two years later, Heinz merged with Kraft Foods. He bought 326 million shares during this merger at a cost of around $24.6 billion. He has held on to that stake, which is now worth $11.4 billion.

The Oracle of Omaha, Warren Buffett, is arguably one of the most famous investors of all time. Many investors have sought to replicate his investing strategy as emphasized by the holdings of Buffett's multinational conglomerate Berkshire Hathaway.
