"The top three soda brands - Coke, Diet Coke and Pepsi-Cola - remained unchanged."
Good point. The way the article is worded is confusing.
And I don't understand how soda sales can fall 1.7% yet the top 3 brands remain unchanged. That makes no sense.
That is nowhere in the link.
"Excluding fast-growing energy drinks such as Red Bull and Monster Beverage Corp products, soda volume would have fallen 1.7 percent, the newsletter said."
Pretty sure they were talking about the stock price and not beverage sales. If soda sales decline 1.7% you can bet the top brands are the cause.
No they can't be, Diet coke is not it's own company.
