Speaking only for me, the reason I never short is I am basically betting against Janet Powell and the magical printing press. That is not a bet I a willing to make. Unless the infrastructure bill gets derailed by amendments (a possibility but not highly likely), it is gonna move industrial stocks. If you truly want to bet against something (and I wouldn't), maybe go 3x inverse QQQ (SQQQ) as the bulk of tech has reported already and it could see some unwinding.
Again I am not a short guy. I prefer to use pullbacks to add to longs or open new longs at discount prices. Also to write out-of-the-money puts on shit I wouldn't mind owning if I get exercised.
edit: Thinking this through a little more. You have the possible lockdown requests, while cases are up, deaths are down sharply. The housing moratorium has expired. Cruise industries can be ripe for a short play but DeSantis is backing them 100% so it may not really crater. Big pharma could see a drop as the press is finally admitting the vaccines dont do shit and more stabs aren't going to help. Big oil could take a hit if the big blue states try a lockdown in Aug. But remember unlike last year, the courts aren't closed this time around. Expect lawsuits opposing any large scale lockdowns to be insta-filed and no Governors still have emergency powers I believe.
tldr: there is a ton of variables to consider but they go in different directions. Markets hate uncertainty, but will it overcome the Powell Put?
