--FILE--View of the Shenzhen Stock Exchange in Shenzhen city, south Chinas Guangdong province, 24 January 2009. The operator of the Nasdaq Stock Market, which has seen a falloff in new listings amid depressed market sentiment, expects a slight rebound in listings from China on U.S. exchanges, but expressed concern that new Chinese rules may prevent some Chinese companies from listing overseas. Robert McCooey, senior vice president of new listings and capital markets at Nasdaq OMX Group Inc., said he expects about 20 Chinese companies to list in the next 12 months on both the Nasdaq and the New York Stock Exchange. But he said that potential listings depend on Beijings willingness to continue allowing companies to list abroad, as well as a stable market outlook. China has been encouraging companies to list in Shanghai and Shenzhen, and has put in place regulations that make it more difficult for companies to establish vehicles incorporated abroad, often a precursor to an overseas listing.
