Technically, $4 remains to be an important resistance for XIN to break. But with obvious institutional investors' support, XIN may pass $4 in a way easier than most of us expect.
XIN's fair value based on its business is $25 now. There are huge room for XIN to go up in 2013. Will XIN tops its her IPO price $14 anytime soon? I don't know. But I am sure she will get there in not very long future as long as all market conditions stay the same or continue improving.
