Correction to my previous post. Trades were not on the Naz, they were on the US-OTC exchange. (maybe one day they will be on the Naz)
Also, no pricing arbitrage. Buying on TSX at 1.04-1.05 then selling into US at 0.80 leaves nothing for profit at days exchange rate. Therefore it would appear RJ to be buying for a US client.
Quiet week all around before Labour Day weekend. Chart looks like it wants to breakout higher.
