The Hang Seng Index (HSI) is a freefloat-adjusted market-capitalization-weighted stock-market index in Hong Kong. It is used to record and monitor daily changes of the largest companies of the Hong Kong stock market and is the main indicator of the overall market performance in Hong Kong. These 66 constituent companies represent about 58% of the capitalisation of the Hong Kong Stock Exchange.[1]

HSI was started on November 24, 1969, and is currently compiled and maintained by Hang Seng Indexes Company Limited, which is a wholly owned subsidiary of Hang Seng Bank, one of the largest banks registered and listed in Hong Kong in terms of market capitalisation. It is responsible for compiling, publishing and managing the Hang Seng Index and a range of other stock indexes, such as Hang Seng China Enterprises Index, Hang Seng China AH Index Series, Hang Seng China H-Financials Index, Hang Seng Composite Index Series, Hang Seng China A Industry Top Index, Hang Seng Corporate Sustainability Index Series and Hang Seng Total Return Index Series. Hang Seng in turn, despite being a public company, is controlled by another listed international financial institution HSBC Holdings plc. Both HSBC Holdings and Hang Seng are constituents of the index.


Ho Sin Hang, chairman of the Hang Seng Bank, conceived the idea of creating the Hang Seng Index as a "Dow Jones Index for Hong Kong".[2][3] Along with Hang Seng Director Lee Quo-wei, he commissioned Hang Seng's head of Research Stanley Kwan to create the index,[2] which debuted on November 24, 1969.[3]


When the Hang Seng Index was first published, its base of 100 points was set equivalent to the stocks' total value as of the market close on July 31, 1964. Its all-time low is 58.61 points, reached retroactively on August 31, 1967, after the base value was established but before the publication of the index. The Hang Seng passed the 10,000 point milestone for the first time in its history on December 10, 1993 and, 13 years later, passed the 20,000 point milestone on December 28, 2006. In less than 10 months, it passed the 30,000 point milestone on October 18, 2007. Its all-time high, set on January 26, 2018, was 33,223.58 points[4] at closing. From October 30, 2007 through March 9, 2008, the index lost 9,426 points or approximately 30%. On September 5, it fell past the 20,000 mark the first time in almost a year to a low of 19,708.39, later closing at 19,933.28. On October 8, 2008, the index closed at 15,431.73, over 50% less than the all-time high and the lowest closing value in over two years. On October 27, 2008, the index further fell to 10,676.29 points, having fallen nearly two-thirds from its all-time peak, but passed the 20,000 point milestone again to 20,063.93 on 24 July 2009. The index reached 25,000.00 on August 19, 2014, reaching as high as 25,201.21 that day, later closing at 24,909.26 points. It continued rising to hit 26,000 on April 8, 2015 with a close of 26,236.86 The following day, it rose to as much as 27,922.67 before closing at 26,944.39. Yet again, another milestone was reached on April 13, 2015 rising to over 28,000 points, or closing to 28,016.34, the highest since December 2007. On July 8, 2015, the index fell as much as 2139 points. On 21 August the index entered a bear market. The index at that point hovered around 18000-19000 points,[5] until it ended in February 2016. In 24 June 2016, the market fell 1,000 points in response to UK EU referendum results that "Leave" won the vote against "Remain". Then, the markets continuously fell on 27 and 28 June 2016 before recovered slightly on 29 June 2016.

The Hang Seng Composite Index Series (恒生綜合指數) was launched on October 3, 2001, targeting on providing a broad standard of the performance of the Hong Kong stock market. It was last revamped on March 8, 2010, and comprises 307 constituents (will become 306 from August 9, 2010[citation needed]).

To ensure the impartiality of its operation, Hang Seng Indexes Company Limited established an Independent Advisory Committee to give advice on issues pertaining to the indexes, including constituent changes and the development of new indexes.
