I don't think the transfer agent can know who has stock and who is trading if the shares are not being held physically. In example, I don't have physical possession of my shares, they are all in my brokerage account which is probably the case for many or maybe most of us. I talked with him a week ago, asking for the number of shareholders there are on record. He told me (sorry, forgot his name but have it written down somewhere) he only had the number of unrestricted shares (see post #75305: 74,136,342) .
