In a recent video, Motley Fool contributors Jason Hall and Tyler Crowe discuss why Realty Income (NYSE: O) and Ternium (NYSE: TX) are top high-yield dividend stocks to consider buying in May. According to the Stock Advisor analyst team, Realty Income did not make their list of the top 10 stocks to buy now, but the ones that did could potentially offer significant returns in the future. For example, consider Nvidia, which made the list in 2005 and has since seen impressive growth. Stock Advisor has outperformed the S&P 500 since 2002 with its expert guidance and regular stock picks. Both Hall and Crowe have positions in these stocks, and The Motley Fool recommends Realty Income. Remember to always do your own research before investing, and be aware of any potential conflicts of interest.
