The stock market action is not delusional. We were at all time highs on the broad markets, and to contain the spread of the virus we are going to have to continue to cancel basically any activity that involves large groups of people in close proximity (as in the same actions being taken in China, South Korea, Italy and increasingly Japan). These containment actions are causing a big contraction in economic activity, and while the contraction is temporary (lasting hopefully only a few months), it is going to have a real impact on companies, with many sectors experiencing sharply lower near term revenue & profits, with likely bankruptcy’s in some specific areas (unless bailouts occur).
I don’t see how a big pullback from all time highs isn’t a reasonable reaction given the current scenario unfolding.
