If you’re a regular investor, that is someone who puts money into the markets every month whether through mutual funds or stocks, you must NEVER stop your investing. Feel blessed that the markets are falling because you’ll be buying at lower prices and the benefit of this will show 10 years from now. I have seen people advise that investing must be stopped and one must wait for the markets to come up. Absolutely foolish advice. If you have a long time horizon and the stomach to see downfalls, be happy when the market falls. You will end up making more wealth than someone who tries to time the markets.
