RE:RE:RE:RE:RE:Short SqueezeUmmm. Not exactly how it works. Shorts do need shares in order to sell them. They borrow them. There is a cost to borrow the shares. They borrow them from custodians like RBC Dexxia, State Street which big pension funds and mutual funds use. The funds get a piece of those fees or pay super cheap custody fees to allow the custodian to lend. or the shorts borrow from the brokers they do the trades with. Your shares, as a retail investor, can not be used to lend to short sellers unless you have outstanding margin in your account. If you buy cash only, or for a tfsa or rsp, those shares can never be lent to shorts.
