Phrases like “earnings movers” and “intraday highs” don’t mean much to the average investor, and in many cases, they shouldn’t. If you’re in it for the long term — with, say, a portfolio of mutual funds geared toward retirement — you don’t need to worry about what these words mean, or about the flashes of red or green that cross the bottom of your TV screen. You can get by just fine without understanding the stock market much at all.
It’s likely some of these Americans might rethink pulling their money if they knew how quickly a portfolio can rebound from the bottom: The market took just 13 months to recover its losses after the most recent major sell-off in 2015. Even the Great Recession — a devastating downturn of historic proportions — posted a complete market recovery in just over five years. The S&P 500 then posted a compound annual growth rate of 16% from 2013 to 2017 (including dividends).
However, it might be best to not become too much of a market "expert". Some of the most famous and successful investors of all time, such as Peter Lynch, the famed manager of the huge Fidelity Magellan fund. He suggested that looking for clues in normal life is a great way to find opportunities. Lynch used to closely follow the shopping habits of his wife to see what brands people were buying. He believed that most people working professionally on the NYSE lived in a bubble.
