Regular market followers know that Chinese Internet ADRs have been on fire lately. Below we highlight our trading range charts for four of the biggest ones to show just how hot they have been. SINA has been the most ridiculous one of the bunch, going parabolic over the past few trading days. The stock is already up 110% year to date. Compared to SINA, the roughly 50% year to date gains for Baidu (NASDAQ:BIDU), Sohu.com (NASDAQ:SOHU), and NetEase.com (NASDAQ:NTES) look paltry, but all of these names are trading in extreme overbought territory at the moment as well. Be careful out there!
