Lungman-it would take too long to dissect Cato's made up conversation, but just for openers no, MM's (and there weren't any) do not receive a "bulk cert" that they trade against.
Take this statement .. ""When a company issues an O/S, bulk certs are created for any brokerage house that wants to sell shares in the company."". HOGWASH !!!! For one .. the brokerage houses do not sell shares. The Company creates the shares and these are printed by the T A and they ALL have names on them .. usually individual names .. NOT BROKERS. They go out snail mail to those whose names are on them and it is these people who in turn deposit them with their broker. It is utterly amazing how we are still having comprehension problems at this late date.
