I'm not sure how significant it is but there is a broker, number 079, which often appears as the representative of clients trading AUM shares on the TSX. In 22 AUM trades shown on the TSX site today broker 079 has represented the buyer 10 times, the seller 14 times and both the buyer and seller in the same trade 7 times. Broker 079 apparently has more than one client who is taking a keen interest in, and having a significant effect on, the AUM share price.
