Income investors love stability. A rock-steady stock chart comes in handy if you ever find a reason to sell your cash-dispensing shares, but predictable dividends are where the real magic happens.

If you bought your first Coke shares when the company first started paying dividends, then you've nearly doubled the return of the Dow Jones Industrial Average (DJINDICES:^DJI) by now.

Coca-Cola makes General Electric (NYSE:GE) and Alcoa (NYSE:AA) look as random as lottery tickets, and even ExxonMobil (NYSE:XOM) trails far behind these unstoppable increases:
