I sold my positions in late January and went all cash. I bought back in late March at (almost) the bottom, and am doing quite well. You can call it dumb if you want, but I'm winning while bears are missing opportunities. When I saw the market down 40% from all-time highs, I just knew it was very oversold.
I'm not opposed to taking bearish positions, but right now, the bear argument doesn't make much sense, considering the pandemic threat is at the tail end.
