Xinhua recently reported that, in the first half of this year, only one Chinese company had its IPO in the U.S. stock market. That one stock dropped below its issuing price on the first day it was offered. It seems the “IPO window” for Chinese stocks will not be open this year. Given this circumstance, 14 Chinese companies went through the privatization process in order to withdraw from the U.S. stock market. There are two primary reasons for this situation: 1) The poor performance of the global economy has resulted in U.S investors having a conservative attitude; 2) The China-Concept stocks are still suffering from their poor credit background.
