It is interesting... Thanks for this Undaunted.

Question -

Does the relatively small net buy volume, as compared to the buy/sell volume for each of these broker houses imply that it is being mostly technically traded, or that these companies represent a breadth of interest in the company that is split both ways?

Also, do you ever see small institutions / wealth management funds buying through e*trade or commsec, or is that purely retail? And how do large superfunds buy and sell stock?
