My 2 cents:
Anyone who had a real business, which had solid fundamentals and was run 100% kosher, will be fine. He got a PPP, got/will get an EIDL, and will get Main Street lending. If he laid off employees, they got basically full income and are ready to come back end of July at the latest.
Interest rates are low, anyone in resi or multifam Real Estate will be fine, his property will only be more valuable now.
Nursing homes were handed very large grants and will have a lot more gov funding after this as well, to make up for higher payroll and less patients. Actually, this crises may have saved the industry.
All medical will do very well.
Retail sucked since early 2010's, don't blame covid. Jewish (specialized) retail is already back to full boom in the tri-state.
Simchas will not change (except only in the very very short term).
Anyone in Amazon, well - thats what happens when you get into someone else business, Bezos calls the shots. It's a risk that is unrelated to Covid. And now online sales will pick up so hang in there, 2021 will be a homer.
And any guys who worked for cash "schwartz" or stam churn here and there: Get a normal job and do things right, because when things go south the gov will now take care.
Proof all the this true - the markets.
