The story
Securities market
Reports of securities trading in Hong Kong date back to the mid-19th century. However, the first formal market, the Association of Stockbrokers in Hong Kong, was not established until 1891. The Association was renamed the Hong Kong Stock Exchange in 1914.
A second exchange, the Hong Kong Stockbrokers' Association was incorporated in 1921. The two exchanges merged to form the Hong Kong Stock Exchange in 1947 and re-establish the stock market after the Second World War. Rapid growth of the Hong Kong economy led to the establishment of three other exchanges – the Far East Exchange in 1969; the Kam Ngan Stock Exchange in 1971; and the Kowloon Stock Exchange in 1972.
Pressure to strengthen market regulation and to unify the four exchanges led to the incorporation of SEHK, the Stock Exchange of Hong Kong Limited in 1980. The four exchanges ceased business on 27 March 1986 and the new exchange commenced trading through a computer-assisted system on 2 April 1986. Prior to the completion of the merger with HKFE in March 2000, the unified stock exchange had 570 participant organisations.
Hong Kong Securities Clearing Company Limited was incorporated in 1989. It created CCASS, the central clearing and settlement system, which started operating in 1992 and became the central counterparty for all CCASS participants.
Penny stocks fiasco
In April 2002, HKEX launched a study to consider the delisting of "penny stocks" to improve market efficiency. Its 25 July 2002 proposal to cancel listings of companies trading below HK$0.50 for 30 straight days hit penny stocks hard. Seventeen companies' shares lost more than 30 per cent of their value, and about HK$6 billion in market capitalisation was wiped off 105 listed companies. Activist investor David Webb said that HKEX's desire to delist stemmed from these companies generating very little revenue for the exchange but taking up a disproportionate amount of staff resources. Webb decried the conflict of interest between its role as operator and regulator, and called on the regulatory role to be passed to the SFC.
On 10 September 2002, a government report was released which found HKEX Chief Executive Kwong Ki-chi guilty of administrative mistakes and said he "should be held responsible on behalf of the HKEX for any major policy shortcomings in the preparation and release of the consultation paper".
Base metals market
In June 2012, HKEX announced its cash offer to acquire the London Metal Exchange (LME), the world's premier metal exchange since its founding in 1877, for GBP1.388 billion. The acquisition was completed in December 2012.
HKEX is also the majority owner of the Qianhai Mercantile Exchange, a commodities trading platform in mainland China which has yet to officially begin operations. The Qianhai Authority has given the green light to HKEX to set up the commodities platform in the special economic zone, but official crackdowns on spot trading platforms in mainland China have caused a delay.

Merger speculation
After the New York Stock Exchange announced in November 2006 that it would open an office in Beijing to work with the Shanghai Stock Exchange, Hong Kong Exchanges and Clearing chairman Ronald Arculli dampened speculation, saying it has no immediate plans to acquire or merge with other exchanges, but would focus on "strengthening our competitiveness and reviewing our listing fees".
In September 2019 Hong Kong Exchanges and Clearing made a proposal to the London Stock Exchange to merge the two companies in a cash and share deal worth £29.6 billion, or £31.6 billion ($39 billion) including debt. If the deal had gone through, the combined exchange would have been the world's third largest after the New York Stock Exchange and NASDAQ in terms of the total value of the companies on the exchanges.
Infrastructure
Computers were integrated on 2 April 1986, which has helped modernise the system. In 1993 the exchange launched the "Automatic Order Matching and Execution System" (AMS) that was replaced by the third generation system (AMS/3) in October 2000.
In February 2018, AMS/3 was replaced by the "Orion Trading Platform - Securities Market" (OTP-C).

HKEX's morning session runs from 09:00 am to 12:00 pm; the extended morning session is from 12:00 pm until 1:00 pm and the afternoon session is from 1:00 pm to 4:00 pm.
HKEX implemented a Closing Auction Session (CAS) in two phases on 25 July 2016 and 24 July 2017. The securities eligible for the CAS include all constituents of the Hang Seng Composite LargeCap, MidCap and SmallCap indices, H shares which have corresponding A shares listed on a mainland exchange and all exchange traded funds. It also includes some regulated short-selling orders.
A Volatility Control Mechanism (VCM), which functions similarly to circuit breakers on US exchanges, was implemented in the securities and derivatives markets on 22 August 2016 and 16 January 2017, respectively.
