Interesting to see periods of 'extreme' PE Ratio of 50/60+ in previous crashes, and in 2020 we haven't seen anything yet. I think it's particularly interesting (which I thought was stating the obvious but apparently to this market it's not) that the swings last for months/years after the initial shake and that is one thing 2020's crash hasn't played out yet.
