One thing I like about US stocks over their Canadian counterparts is the lack of secondary exchanges. My stocks are on a yahoo watchlist, but it only shows TSX volume....so it misses the action on the Alpha, Chi-x, Omega.....we have 8 trading platforms in this country for cripes sakes. And today with volume, as I write this, around 136K, about 40K of the volume is on alternative exchanges.

Anyone have any thoughts on this? Does heavier trading on secondary exchanges have any significance?
