They're expensive already but I would stick to the walmarts/amazons at this point. No matter what ppl will still need to buy food etc. And our shopping will move online even faster than it already has.
Even banks. Wait for them to really get fukkd then go in. The country will not allow banks to fail. You'll make your money and then some.
To me stocks don't make sense unless you're in it for the longish haul. I don't mean 20 yrs, but I would say 5+
All this short term hi frequency trading - unless you're playing with hundreds of thousands of dollars once you pay short term capital gains tax etc, you're kinda wasting your time.
