Registered stock. In Great Britain registered stock is stock registered in the name of the owner
in the books of the company issuing it, although the owner receives a certificate of stock as well.
This certificate, however, is not a negotiable instrument; the possession of it does not carry with it
the ownership of the stock. Before the stock can be transferred to another the signature of the
owner (or of his attorney) is again required; the certificate must also be surrendered.
