According to a historic study conducted by Ned Davis Research, companies that either initiated or increased their dividend payout policies between 1972 and 2007 outperformed their S&P 500 counterparts with stagnant dividends by 2.2%, annually. Compounded over a 35-year span, this marginal annual contribution would increase the total portfolio return by 114%.

TUTORIAL: Managing Risk And Diversification

Not Just a Dividend
Despite the fact that dividends provide regular income to shareholders, and thus are commonly held by pension funds and other institutional investors, dividend hikes also reflect management's belief in the growing fundamentals of the company. A dividend increase often reflects improved cash-flow conditions of the firm. Therefore, looking for stable companies with a long history of dividend increases allows investors to gauge management's long-term expectations of the firm.

The following seven companies (from a wide range of industries) support strong dividend yields and have been increasing their payouts. In fact, all of the corporations mentioned below have seen their payouts grow by at least 15% over the past five years. These stocks should not only be seen as income producing instruments, but have the potential to provide long-term portfolio appreciation.
