There is a period that he cannot sell his shares. Also if he do this purposefully it would be a crime.
You can usually sell shares even during a lock up period but not on the open market and typically at a discount to market.
Are you not worried about overnight moves when liquidity is thinnest? How many times are you checking the price during the night?
If you're not going to close your short, I would consider hedging with a long position in the one of the 'Gamestop' type stocks. Some of those that moved up with Gamestop last time are not out of whack on a fundamental basis, e.g. Nokia, Ericcson. These are long term 5G plays too. Nokia Ericsson
Should have gotten out when i said. Each day GME goes up proves how big brain i am and how small pp you are Mr Dense. ET will not be here to help you when you lose your farm.
Next time around, I'm not sure Robinhood will help out the shorts by restricting trading in Gamestop and the others. They already got hammered in the media the first time they did this. I'm guessing most of the posters on here (myself included) have been on the end of something like this. At least there is some minor consolation that a few hedge funds will also be getting run over.
