This ridiculously cheap Warren Buffett stock could make you richer

Could one of Warren Buffett's rare losers be a winner for your portfolio?

Berkshire Hathaway, led by Warren Buffett from 1965 until his retirement at the end of 2025, holds numerous consumer staples stocks in its equity portfolio. However, it may be one of Berkshire's most poorly performing investments that offers the greatest opportunity to new investors.

At the end of 2025, Berkshire Hathaway held a 27.5% stake in Kraft Heinz (NASDAQ: KHC). At current prices, Berkshire's stake is worth around $7.8 billion, but its cost basis for the investment was around $9.8 billion.

Before taking a $3.8 billion impairment charge last year, the position's book value was $12.2 billion.

Recently, there's been talk of Berkshire, now under the leadership of Buffett's successor, Greg Abel, selling off the Kraft Heinz stake as the packaged foods company was considering splitting into two. Kraft Heinz has since put those plans on hold, and Berkshire appears content to hold Kraft Heinz stock for now. While it's unclear whether Berkshire sees better times ahead, much suggests to me that a comeback could be in motion.

Buffett may have handily beaten the S&P 500 index over many decades, but even legendary investors have their share of losing investments. Berkshire's involvement with Kraft Heinz goes back to 2013.
