Shenzhen Stock Exchange is one of the People's Republic of China's three stock exchanges, alongside the Shanghai Stock Exchange and the Hong Kong Stock Exchange. It is the 9th largest stock exchange in Asia by market capitalisation (2008), and is based in Shenzhen, China.
The Shanghai and Shenzhen stock exchanges list more than 1,500 companies with a combined market capitalization of US$2,658.2 billion (2008), rivaling the Hong Kong Stock Exchange (US$2,121.8bn) as Asia's second-largest stock market behind the Tokyo Stock Exchange (US$3,925.6bn).
Most of the companies within this market belong to listed company in which the Chinese government maintains controlling interest. With regards to the listed companies, the government has viewed the stock markets has means of raising capital, but there is no current interest to privatization or selling off the state controlling interest in the SOEs (State Owned Enterprises). Until 2005, two-thirds of the shares in listed companies were non-tradable on the exchange, creating a problem in which the tradable shares were valued higher than their proportion in the company. In 2005, as part of the Chinese stock issue reform, the non-tradable shares were made tradable and the holders of tradable shares were compensated by having extra equity in the company.
The new index is composed of major firms such as Shenzhen Development Bank, property developer China Vanke Co Ltd and Guangdong Electric Power Co. Index components account for about 40 percent of the Shenzhen bourse's capitalization, 61 percent of the combined after-tax profits of Shenzhen-listed companies, and 43 percent of turnover.
The Shenzhen exchange will adjust the index's components every six months.
The central government shut down trade on the Shenzhen and Shanghai Stock Exchanges for over a week from May 1, 2003 to fight against Severe Acute Respiratory Syndrome (SARS).
