This is my primary observation, with tech, banking, energy, industrials, travel all up recently - and the other sectors down - anything we didn't get to do in 2020 is a winning trade now while the companies that sell the goods, services, and other things we were heavily using in 2020 are falling out of favor.
I'm not sure what's going to happen - I think 78 may be right, that we're still a few months off from any sort of collapse/crash. But I'm worried, because I've taken a beating even on some of my "safe" stocks (like APPL, WMT, LOW, CVS). I have about 25% in cash, but that other 75% is down close to 15%.
