If you’re looking for passive income, dividend stocks can be a great investment. But many of them have wild swings in yield based on the ups and downs of share pricing. Known as Dividend Kings, there are just over 50 stocks that have consistently raised their dividends each year for the past half-century. Three of them in particular have everything in place to maintain these annual increases for decades to come.

Walmart (NYSE: WMT)

Walmart may be a stodgy, tried-and-true retailer, but it’s outperforming such heavy-hitting growth stocks as Microsoft, Apple, and Amazon. For a while, the company was facing noticeable declines in operating margins even as its revenues grew. But Walmart has completely turned that around. Smart investments in store remodels, new store openings, and especially the Walmart+ home delivery option are paying off. Walmart recently increased its dividend by 9%, and further raises likely lie ahead.

Procter and Gamble (NYSE: PG)

P&G isn’t too exciting, but it’s incredibly reliable. The company owns a laundry list of personal care, beauty, and home care brands, from Cover Girl and Gillette to Tide and Febreze. It’s raised dividends annually for an eye-popping 68 years. P&G’s dividends are up by 56% over the past decade, and last year’s total dividend payout was more than $9 billion. Those looking for a safe dividend option would do well to consider P&G.

Illinois Tool Works (NYSE: ITW)

ITW sells primarily to commercial and industrial clients, so many consumers haven’t heard of it. But the company has seven core segments, from food equipment to polymers and fluids. This diversity helps to protect ITW from market fluctuations. The company’s margins are currently growing across all segments, causing its return on capital employed (ROCE) to skyrocket. This well-run company with a long history of success is definitely worth a closer look.
