Dividend Yield: 10.1%
Market Cap: $181 million

Main Street Capital (MAIN) is a business development company specializing in equity and debt investments in small and middle-market companies.

With economic conditions improving and small companies looking to enter growth mode instead of just staying on the defensive, Main Street could see some brisk business in 2010. The company pays a monthly dividend instead of a quarterly payout, meaning a steady flow of cash for income investors.

Dividends are an often overlooked but crucial part of a successful retirement strategy. These quarterly offerings can provide a regular "paycheck" for retirees -- especially when the company is a high-yielding blue chip with a track record of boosting its dividend year after year.

But dividends don't just have to be a quiet way to grow your nest egg. They can really supercharge your returns when you buy into a great stock that also happens to be cash-rich. On top of the appreciation you see in your shares, you'll also get a great bonus checked mailed four times a year -- or more, depending on the dividend schedule.

Wall Street's equity market offers a full schedule this week, with 8 IPOs and 5 Secondaries on the docket.
