The lists you are looking at above (Post #: 47603313) are of brokers who put the trades through the market. Taylors and Shaws are brokers.

They are selling (or buying) shares for various clients of theirs - rarely are the shares "their own".

It is these clients you will find on a list of holders. But often bigger clients keep their holdings in Nominee Accounts - not under their own names.

Here are two of the nominee accounts on the CDX Top 20 from the last Annual Report:



Only people within the industry would really know which brokers are acting for which clients.
So the broker data above is used to look at things like whether retail brokers (ComSec, CMC) are doing the trading or is it brokers with big private clients or ....
The data is also useful to see what proportions of selling and buying are coming from which houses.

Hope that helps a bit.
