BOSTON ( TheStreet Ratings) -- This month, I'm starting the Dividend Stars Portfolio, selected from a review of companies poised to provide excess returns over the next 12 to 24 months. The diversified 13-stock portfolio offers investors growth and income.My Dividend Select screen picks companies that generate above-average dividend yields and show the potential for share-price appreciation. The monthly screen, begun Feb. 14, lists 100 companies that have collectively outperformed the S&P 500 by 4.2 percentage points. (Sign up for our Dividend and Income Newsletter.) The Dividend Stars Portfolio is derived from the Dividend Select screen.
