If you’re not leveraged and didn’t invest money that you need in the short to medium term, and the companies you invest in will probably recover unless they have more structural issues. I was down 30% in April, I bought more and now I’m up. Normally I can make this move because I have no debt and I don’t need the cash.
Also, I am not a trump supporter so I’m not sure why you keep saying he is my savior ?
