 The 
                      Hong Kong Stock Exchange (traditional Chinese: abbreviated 
                      as HKEX; SEHK: 0388) 
                      is the stock exchange of Hong Kong. The exchange has predominantly 
                      been the main exchange for Hong Kong where shares of listed 
                      companies are traded. More commonly known as the Hang Seng 
                      Index, it is Asia's second largest stock exchange, behind 
                      the Tokyo 
                      Stock Exchange. Hong 
                      Kong Exchanges and Clearing is the holding company for the 
                      exchange. |  |  |  
 HistoryThe history 
                of the securities exchange began formally in the late 19th century 
                with the first establishment in 1891, though informal securities 
                exchanges have been known to take place since 1861[1]. The exchange has predominantly been the main exchange for 
                Hong Kong despite co-existing with other exchanges at different 
                point in time. After a series of complex mergers and acquisitions, 
                HKSE remains to be the core. From 1947 to 1969 the exchange monopolized 
                the market.

                launched the "Automatic Order Matching and Execution System" (AMS) 
                that was replaced by the third generation system (AMS/3) in October 
                2000[3]. Systems as such were added to meet the increased popularity 
                of online Stock trading. Trading Hours:

                role David Webb, 
                independent non-executive director of the Exchange since 2003, 
                has been arguing for a super regulatory authority to assume that 
                role as regulator, as there is inherent conflict between its commercial 
                and regulatory roles. In the meantime, he argues for improved 
                investor representation on the Hong Kong 
                Stock Exchange. In 2007, the 
                uproar by smaller local stockbrokers over the decision by board 
                of directors to cut minimum trading spreads for equities and warrants trading at between 25 HK cents and HK$2 caused 
                the new board to vote to reverse the decision. The reforms were 
                to be implemented in the first quarter, but was put back on the 
                table following protests by brokers. Webb criticised the board 
                for caving in to vested interests.[4]    References   |
