The US tech index, the NASDAQ, peaked on 2 September 2020 at 12,058 and three weeks later closed at 10,632. On the same days, Apple hit US$137.98 and then fell to US$107.12. These falls of over 10% and 20% seem high but both were simply returning to their early August levels. It's hardly a rout when a month's gains are given back. The bigger issue is whether such stock corrections will scare off the retail 'Robinhood' traders.
