RE:FDR and news release etiquetteYes, 68Charger1. If you have a cash account with a negative balance, that is technically a margin account. So just keep the balance at above zero in order to prevent the custodian/broker from making your shares part of the lendable pool. Those shares remain an asset of your account but if you have a negative cash balance, they may have been loaned out to another investor for a fee. So people think they still hold /own them because they see those shares are an asset of their margin account. They do own them but don't have possession of them for a certain period of time. So if they were to sell them, the custodian/broker HAS TO GET THEM BACK. This is called a buy back. Sometimes they can't gert them back in a timely fashion. In that event, the rental fee goes up and the broker/custodiian tries to find the shares from another client of theirs.
