RE: Who is Bergeron, DonaldAnybody can buy on one exchange and sell on another, if the stock is cross listed, as Sirit's is. The question is why did he sell in the US, since it seems he took a price hit in doing so. He got .2897 US, which translates to (at most) 31 cents Canadian. If he had sold slowly via the TSX he would have done much better, since the pps never went below 36.5 cents on that day. His selling may have depressed the price more but, I don't think by much.
