For those looking to diversify their dividends portfolio, here are five small-cap stocks with market caps under $2 billion from the services sector that are currently offering very high yields (at a rate greater than 10 percent), indicating that they could be of particular interest to investors who are currently inclined towards income producing stocks.

It is important to remember that while high dividend yields are certainly attractive, that percentage alone does not automatically make for a smart investment and other financial information should be considered. For instance, a company that offers a high dividend yield should also have enough cash to make good on those payments. As well, it is important to consider a given company’s history of growth, how positive and consistent this growth has been, and is projected to be in the future.
