With the QQQ in a short term down-trend I am wading into SQQQ. I will be more sure of the down-trend if it reaches 5 days. One of the first rules I teach my students is to hold only stocks in a Weinstein Stage II up-trend. Pandemic stocks like PTON and DOCU and ZM have now entered Stage IV declines. That means they are below their declining 30 week moving average (red solid line in these weekly charts). The big money is made holding stocks in Stage II up-trends. This rule alone could keep most people out of trouble.
