On Oct. 19, 1987, toward the end of my rookie year in the investment business, the Dow Jones Industrial Average ($DOWI) dropped more than 500 points in a single day. Now, that barely gets noticed.
Because as Wall Streeters and POTUS are fond to say, the Dow just hit 50,000. So a 500-point move now is only 1%. In 1987, that one-day plunge was more than 22%. Yes, in a single trading day.
