I am by no means a sophisticated investor. I try to read a lot. I Pay for a couple of services that have passed along some good advice. I’ve wouldn’t even know how to short or buy on margin.
Buy low, sell high is what I try to do. I also adhere to a saying Jim Rogers used in Investment Biker and Adventure Capitalist (great books BTW).
I don’t think he coined it, but he put it into practice.

“The best time to buy is when there is blood in the streets”.

With 120k cases per day in the US alone now, IMO, is that time.
