Chart of the Day: Has Warren Buffett's Coke Finally Gone Flat?

Berkshire Hathaway holdings have been hit lately by Coca-Cola shares: it looks like a long-time stock that's backed by Warren Buffett has gone flat. That means revenue, as well as share price, and Coca-Cola's grip on the market as top sodamaker could mean less, as more Americans count calories and cut unhealthy beverages for optimal options. This has Coke making moves into coconut water -- with its 2013 Zico buy -- and shuffling executives. For one, its chief marketing and commercial officer is stepping down, and being replaced next year. Today's Chart of the Day is another Buffett top pick.
