Before considering dividend investing, you should understand that companies never guarantee dividends. Stock prices can rise and fall. Your investment is not guaranteed and may lose value. When screening dividend-paying stocks, consider all factors about them—not just high yield—because the higher the potential yield, the higher the potential risk.  The site’s articles are frequently published and address news as well as more general topics. In addition to free content, including stock recommendations, strategy explainers, tools, calculators, and advice, Dividend.com offers a newsletter and a premium service for paying members. Investors looking to bone up on strategy or research specific stocks will find a lot of information to help them on this thorough site, although some content is flagged for premium members only. The site provides detailed dividend data for the casual visitor, which you can find by searching by ticker symbol. It also offers a few free tools like the dividend growth calculator. To use its ex-dividend calendar, Dividend Scorecard, 20-year rolling history of dividend data, and other premium features, you’ll need to pay a monthly or annual fee. Premium content is updated five times a day, which some investors may find is plenty. Dividend Investor also publishes articles on its homepage, informing investors with topics such as highlighting companies going ex-dividend in upcoming weeks or identifying companies that pay monthly dividends. The Dividend Detective’s home page offers plenty of useful, free content to educate investors who are new to dividend investing. This free content includes information on preferred stocks, closed-end funds, REITs, and Canadian stocks, as well as content on U.S.-based high-dividend stocks. Basic training and advanced tutorials will explain terms and investing strategies. The site’s premium content includes breaking news and model portfolios, which could be useful for investors looking for a little more hand-holding. Spurred by investors eager to learn more about strategies for growing dividend income, The Dividend Growth Investor also offers a newsletter documenting building a portfolio from scratch and showing the gains over time using their system. Investors interested in seeing real-time progress may find it a useful addition to their inbox. Members have access to lists of pre-screened dividend-paying stocks, high yield stock ratings, high yield REITs and other stocks. Premium content is updated once per month, which may not suit investors hungry for the latest information.
