Nov. 18, 2009 (Chinavestor) Earnings and momentum keep pushing Chinese stocks higher. But be careful for the rest of the week because profit taking can hurt overbought stocks. Yanzhou Coal (NYSE:YZC) and China Automotive Systems (NASDAQ:CAAS) are in the danger zone while Sina Corp. (NADAQ:SINA) has more upside left. Chinese airliners fell on Tuesday, as expected. Our advice and email alert sent to subscribers on Monday was a sound advice indeed. WuXi Pharma Tech (NYSE:WX) is out of the overbought list while Canadian Solar (NASDAQ:CSIQ) and Solarfun Power Holdings (NASDAQ:SOLF) are worth paying close attention to.
