Buffett's pick: Kraft Heinz Kraft Heinz (NASDAQ: KHC), the third-largest food and beverage company in North America, is a top-five holding in Buffett's portfolio today. Owing to 40-year-high inflation, the Fed's decision to hike interest rates as a result, and unsettled fears in connection to the war between Russia and Ukraine, investors have dumped growth stocks and swarmed to value-oriented businesses. Not only are high-growth companies adversely impacted by rising interest rates, but many of them are also riskier plays due to their lofty valuations and lack of net profits.
