It can go much much higher.. Just like we kept dropping relentlessly week after week.. now we can go up week after week..
Of course I dont think so but hey, always leave that possiblity open.. Especially when shorting. Limtex is right in that there is no limit to the loses on a short position :)
I am waiting as well, no reason to rush in, except that I just reestablished my second position on USPI here at $19.96, they gave me a discount of $2 plus, go to take it (still have the first position from above $21, though).
