There are many reasons why investors want reliable yields, including predictable cash flow, protection against volatility and inflation, and compounding returns. When it comes to timing, there is virtually no bad time to buy yield.
The question is which dividend stocks are good buys in July and set up to deliver market-beating yields as their share prices rise. In the end, it's all about total returns. A high yield is only as good as the underlying stock. If the stock price falls to offset the gains, investors would be better served investing elsewhere.
