The ability to invest and block out the noise surrounding your investments has always been a very difficult thing. Some of this noise comes from economic events, while a large portion is strictly the forecasts of “experts,” expressing predictions of stock prices for year-end. This noise causes people to invest in stocks with the belief that these predictions are reliable. Rather than acting on these individual predictions of stocks and positions, following the classic trends that exist within the stock market itself is more advisable. If you have a portfolio that is diversified to your liking, there are much better rules of thumb to follow. This allows you, as an investor, to focus on the portfolio as a whole, without worrying about individual forecasts of returns. In “Good Enough,” Morgan Housel of The Motley Fool discusses the inherent desire to have precise forecasts, the improbability of the success of forecasts, and the rules of thumb that help investors rest easier at night.
