All investors love getting big returns from their portfolio, whether it's through stocks, bonds, ETFs, or other types of securities. But for income investors, generating consistent cash flow from each of your liquid investments is your primary focus.Cash flow can come from bond interest, interest from other types of investments, and of course, dividends. A dividend is the distribution of a company's earnings paid out to shareholders; it's often viewed by its dividend yield, a metric that measures a dividend as a percent of the current stock price. Many academic studies show that dividends make up large portions of long-term returns, and in many cases, dividend contributions surpass one-third of total returns.Zions in FocusHeadquartered in Salt Lake City, Zions (ZION) is a Finance stock that has seen a price change of 21.01% so far this year.

However, not all companies offer a quarterly payout.For instance, it's a rare occurrence when a tech start-up or big growth business offers their shareholders a dividend. It's more common to see larger companies with more established profits give out dividends. During periods of rising interest rates, income investors must be mindful that high-yielding stocks tend to struggle. With that in mind, ZION is a compelling investment opportunity. Not only is it a strong dividend play, but the stock currently sits at a Zacks Rank of 3 (Hold).Want the latest recommendations from Zacks Investment Research?
