mr cawkwell,you'd be better to study qxl , and the auction market, then take a look at allegro.pl cash in bank, take a look at some of their shareholders , both from within Izaki,and florry. and note they are serious guys out to make money.
izaki, group have done lots of deals with ebay,google through their other businesses. they know how to sell on groups for big markups.
and so do florry.and their backers.
ps if you want to play qxl, you'd make more going long than short.eg if can afford some cash then buy in tomorrow, tell all your people, then sit and wait , and wait for allegro to rejoin qxl < with russia,czech,hungary added as well> .THEN keep waiting for the bid . AND I am sure you will get £200 plus per share.
pps don't leave it too late.
