I think sohu just got taken down with the rest of the sector, possibly because of etfs and funds.
Bidu,sina,renn,etc. have been performing poorly, so when people cashed out of the china internet space, it took sohu down with it.
As the guy from "seeking alpha" pointed out in the article, sohu is trading at cash value, which is incredibly cheap.
I believe sohu will be in the high 40"s soon.
