What is the wall of worry?
You may have heard about a "wall of worry" from analysts talking about the stock market. Simply put, it's the tendency of stock prices to increase even as economic, political, or social conditions suggest that they should be falling.
When it comes to the stock market -- or any type of investing, really -- there will always be naysayers. Paul Samuelson, the first American to win a Nobel Prize for Economics, quipped in 1982 that the market had predicted nine of the last five recessions. It’s quite possible that the four that never happened dodged an economic downturn because investors were able to scale the wall of worry.
