In a rational market right now:
The overall market should be down... a bit.
All home leisure related stocks should rocket up as people stay at home, so neflix UP, Amazon UP, all video game stocks UP, all TV stations and ISPs UP.
All car company stock should be up as people plan to avoid public transport in future.
Sure, airline stocks down, theme parks down, football teams down, and so on...
But people are not going to stop earning, or spending money. they just wont do it in large crowds. It would be different if people actually thought this virus would kill off 100 million productive members of the workforce, but no...ironically its most risky for the elderly and sick, who are technically an economic drain!
