You might start to hear more about the "Dividend Kings" over the next few months. Small wonder: Stocks that have boasted uninterrupted dividend growth for a half-century or more might be an ideal place to hide out amid increased economic uncertainty.

Sluggish global growth, rising recession risks and a stock market that hasn't gone anywhere over the past 52 weeks has some market strategists banging the drum for quality stocks.

"A focus on quality stocks can allow investors to stay in the market to benefit from potential upturns, but with a measure of prudence built in to buffer downturns," says Tony DeSpirito, head of BlackRock's U.S. Income and Value team.
