Stock market roller coaster

Have you ever been on a roller coaster going slow down slowly slow it starts flying down flies down down down down down and then it climbs up again flies and twists it back Up again, slowly again. Downward is fast, up is slow. But if you sit tight, you'll reach your destination. The only difference between the stock park and the roller coaster is the stock park by the end you'll be up and the roller coaster by the end you're down.
