Marketwise there may be a serious decline, a bit lower than the last, but it will come back. Yes, many small businesses will disappear and that is sad, but the economy will recover and some would indicate that the current market pattern would have occurred even without the current crisis. Day traders or short term inverters need be more concern and take defensive action more so than long term investors. I am wondering if the consumer goods sector may see a surge, as warehouse orders are way backlogged and will take a while to restock stores. Those that do survive will need to re-hire and thus will reduce unemployment as we gear back up. IT may be the place to be, as the work from home and meet from home demand continues to rise.
As it is written in the Bible in many places, "and it came to pass". Yes this too will pass.
