High-yield dividend stocks can be sources of passive income no matter what the stock market is doing. Many high-yield savings accounts now offer interest rates of more than 4%, which creates a real opportunity cost for investing in stocks that simply didn't exist when interest rates were close to 0%. Devon Energy (NYSE: DVN), Mativ Holdings (NYSE: MATV), and Kinder Morgan (NYSE: KMI) are dividend stocks that not only have significantly higher yields than the risk-free rate, but have growing businesses that could drive share price appreciation, too.
