Everything you need in a top dividend stock
Realty Income is a real estate investment trust (REIT). REITs own and lease properties, and they pay out 90% of their earnings as dividends, which is why they often feature in the dividend portion of a great portfolio.
There are different types of REITs depending on the industry, and Realty Income is a retail REIT. Its client list includes resilient essentials retailers that can perform well in any environment, like Walmart and CVS, and no client makes up more than 3.3% of the total property portfolio. Although 80% of its properties are in retail, it has expanded into other industries like gaming and industrials, and it's also spreading out globally. This lowers its overall risk.
