With Coca-Cola's (NYSE:KO) earnings being released tomorrow, Austin recommends shareholders look at the company's international volume growth as the most telling indication of its long-term promise. In the previous quarter, Coca-Cola raised worldwide volume by 5% -- an impressive feat for a company of this size, but difficult to sustain. With a relatively saturated domestic market, emerging markets such as India and China will be a crucial factor in justifying Coke's not noticeably higher valuation. The stock now trades more richly than competitor PepsiCo (NYSE:PEP).

All of that international growth has been necessary fuel for both of companies' appealing dividends -- which is why we selected one of them for our report about how you can  "Secure Your Future With 9 Rock-Solid Dividend Stocks."
