Warren Buffett has led Berkshire Hathaway to market-beating returns since 1965. Buffett uses a simple investing strategy, and he never chases hot stock market trends like artificial intelligence (AI).

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.

If you know anything about Warren Buffett, you probably greatly admire how he has increased the value of his company, Berkshire Hathaway, by an annual average of nearly 20% over close to 60 years. Buffett has bought many great companies outright and has invested in the stock of other companies.
