You may have heard advice to stay in stocks during a recession. Obviously if the stocks have temporarily fallen in price, you don't want to get out right now. That's called buy high and sell low. Bad idea. Now is the time to invest more (assuming you're not close to retirement) while stocks are undervalued. I read an article recently saying to look at it this way: The stock market is on sale!!
Who can't pass up a good bargain sale?
