I don’t see how it could go up, considering the amount of people NOT working.
The confusing thing about markets is how they are “forward looking.” The price today is based on the consensus assessment of how things will be in the future. If the assessment of the future improves, the price will rise. If the assessment of the future falls, the market will fall.
So, it does not matter whether the future is better or worse than the present. It ONLY matters if the future is better or worse than what people currently THINK the future will be like.
