It's all very interesting to see the buy & sell totals.  Remember these are brokerage operations.  Do you remember when all the banks rushed out to buy brokers?  They are now just operating divisions.  They even have the same broker clearing #'s.   CIBC--Wood, Gundy #79     RBC-- Dominion Securities #2       BMO--Nesbitt, Fry #9     BNS--McLeod, Young, Weir #85 TD--I can't remember #7 but they also  bought the huge US operation of Waterhouse             Natl. Bank--Levesque, Beaubien #80                                  With the new access to capital it allowed these divisions to have greater capability in the very profitable underwriting game & to increase the number & size of margin a/c's.

IMO the trade # totals reflect nothing more than who has the most a/c's trading in ARU.
