The games by CSTI and the other MMs are taking place on the USOTC. IMHO, that indicates the short is here in the US. Also, if the shorter needs to cover millions of shares, doubtful he will find them all on the TSX.
I don`t believe that you are right with your assumption....DSNY is listed at the Toronto stock Exchange since (not sure) 3-4 years (out of my brain), if so the entire Position has build in the US OTCBB before . The ongoing shortage might hve been done in Toronto....which I also don`t believe as for the low volume and if you watch LevelII in the past ther was nothing what really happend in full contrast to what I recognice the ASK pricing of csti.
There also might be the opportunity that they shorted additional Shares in Germany in early2006 as there has been an unusal volume with millions of Shares traded.
And nowhere I mentioned ...they have to cover....I just say "it is the question when it is getting to expensive for them to cover" or what will be the catalyst therefore.
Hope you will understand my english as I am not native Speaker :-)
Original from you
"You ask "How can they not buy back shares?...they have to cover!" The answer is THEY DONT have to cover if they have been shorting on Toronto exchange. "
