A total of 157 Chinese companies have listed through initial public offerings (IPOs) so far this year, raising 144.8 billion yuan in funds, according to statistics provided by Wind Information Co.

Despite the strong IPO momentum, there still are 20 investment banks haven't yet acted as lead underwriters of any IPO this year. Surprisingly, China International Capital Corp. (CICC) and Goldman Sachs Gao Hua, a joint venture between Goldman Sachs and Beijing Gao Hua Securities, are among them.

From 2004 to 2010, CICC has always ranked first or second among Chinese investment banks in terms of funds raised as a lead underwriter.

In 2010, the number of IPO listings by Chinese companies rose 253 percent to a record high of 349 firms, raising 478.3 billion yuan in capital, up 155 percent from a year before.

This year, China's IPO listings have stabilized with a slight decline in the number of IPOs. But the market still has about 20 companies making IPOs every month.

Business advisory firm PricewaterhouseCoopers previously projected the number of IPOs on the Shanghai and Shenzhen exchanges would reach 320 this year, raising an estimated 400 billion yuan.
