if you are some random person with a 401k, for the love of god don't touch it. you should have *already* factored risk into your portfolio based on time horizon etc. hoepfully you did, but starting to actively manage right now is unlikely to helphttps://twitter.com/morganhousel/status/1237386898026438656 …
my personal advice for people with a lower risk tolerance than my usual pack of wild-people, is to take all the long stocks out of the market and put it on a company that you know if going to survive this, like Zoom or 3M.
