June 29, 2010 (Chinavestor) There is a whole lot more room to the downside than to the upside, according to the overbought and oversold monitor below. There is not a single oversold China ADR from a technical point of view while Gushan Environmental Energy (NYSE:GU) and Huaneng Power Int. (NYSE:HNP) became overbought. There is room left to the upside for the rest of the China stock universe including China Unicom (NYSE:CHU) and New Oriental Education & Technology Group (NYSE:EDU) but changes are low that any of these stocks will be able to fight the market on Tuesday. Stocks on the oversold end draw attention are Yanzhou Coal (NYSE:YZC) and Sohu.com (NASDAQ:SOHU).
