While some market observers criticize KO stock as "boring" and " stagnant " and claim the shares basically trade as a bond, some notable investors stand by Coca-Cola and its annual dividend yield of 2.75%, notably Warren Buffett, who has held 400 million shares of Coca-Cola for more than 30 years now and is one of the company's largest shareholders. Of course it helps that Coca-Cola has grown its dividend for 59 consecutive years. And, to be fair, Coca-Cola has not been a slouch. Through the first three quarters of last year, Coke increased its sales by 20% from the same period a year earlier and its operating profit grew by 30%.
