I believe many would sell some of their shares, not all of their shares,
I also believe that some, wouldn't sell any of their shares.
When I first bought AMC, I bought 101 shares of AMC and 50 shares of GME to show support of the Anti Wall Streeters. I saw them camped out while going to Knicks games in NYC. I brought them a dozen donuts for hundreds of kids, they loved me!
I bought many more shares of AMC because I believe it's a good investment, as for GME, I have diamond hands on those shares!
