Coca-Cola has also split its stock four times since Berkshire established its initial position. The company currently owns 400 million shares worth around $24 billion. Berkshire's cost basis for those shares is just $1.3 billion.
From the start of 1988 to the end of 2021, the price of Coca-Cola shares grew 25-fold, and the company reliably pays an appealing and growing dividend. (By comparison, the S&P 500 (^GSPC -0.43%) index increased about 19-fold in the same period.)
But Coca-Cola shares didn't outperform the market throughout that entire 34-year period. For example, from the start of 1998 to the end of 2006, the price of Coca-Cola shares declined almost 28%, while the S&P 500 increased by more than 46%. Over the last half of the 2010s, from 2016 through 2020, Coca-Cola shares increased in value by just 28%, while the S&P 500 index gained 84%.
Buffett has held his shares of Coca-Cola the whole time and maintains his conviction that the beverage giant will continue to produce solid returns over the long term.
