From Investopedia
A nominee account is a type of account in which a stockbroker holds shares belonging to clients, making buying and selling those shares "easier".

A nominee refers to a person or company who has been entrusted with the safekeeping of investors' securities or property; all of your investments are held in its name, while you retain control. The securities are held in trust and the nominee is the legal owner, but you hold on to real ownership as the beneficiary.

So, looks like a convenient way to "hide" who is the actual owner from the wider market !!
