Coca-Cola's stock has pulled back enough to make the 3.1%-yielding shares look attractive for long-term investors. But the real reason for you to trust this company can deliver is actually more fundamental. The big reason to expect Coca-Cola to produce reliable results in the future is, largely, because it has produced reliable results historically. You need to drink, and Coca-Cola sells what is, really, an affordable luxury. Reasonable price, attractive yield, and, the big one, a strong business selling a life necessity at a wide profit margin.
