From Motley Fool:
One of the most vexing questions facing everyday investors is when to sell a stock. Ideally, the answer is never. Warren Buffett, the world’s greatest investor, famously said, “Our favorite holding period is forever.”
Buffett searches for stocks with economic moats — sustainable competitive advantages that should drive profits for the foreseeable future. Coca-Cola, a Buffett favorite, has tremendous brand and distribution power, making the global beverage leader a great example of this kind of stock.
A stock worth holding forever is the best kind of investment.
