790k short trade was accumulated by Jeffries (JEFF)
If you were lucky enough to have your eye on L2 at that time you could see GSCO and JEFF (the market maker code for goldman sachs and Jeffries) trade it off to eachother. It sure has looked as though JEFF was working up a massive short (he was always on the sell side around 31.50). Most likely the boys at Goldman paid a fee for the Jeffries trader to manipulate and slowly work up the position, then they traded it off to Goldman in After hours.
Nothing but the big boys selling into the lemmings at the top like they always do...
Well, GS got their man there in China and they know exactly what is going on there. We can have some great academic discussions on this board about CMED but that does not mean retails' wishes will be fulfilled. With no one to scoop up the shares, CMED will be shorted and longs got to put up with the pain.
