Hang Seng index
an index of the largest companies trading on the Hong Kong exchange
The Hang Seng is an index of the largest companies trading on the Hong Kong stock exchange in terms of market capitalization. It reflects about 56.7% of total activity on the exchange, which is one of the biggest in Asia.
It was founded back in November 1969 with a base of 100 points – and the index can be compared to the likes of London’s FTSE 100 and New York’s S&P 500. Named after the Hang Seng bank, it tracks a total of 50 companies and is the most widely quoted barometer of the region’s exchange.
How the Hang Seng works
During the 1980s, the Hang Seng launched four sub-indices designed to split the stocks being tracked into distinctive sectors: finance, properties, utilities, and commerce and industry. Some of the best-known brands that have a presence in the index include the international banking giant HSBC, and the Chinese conglomerate Tencent, a company often dubbed China’s Facebook.
As with other indexes, constituents in the Hang Seng index are weighted based on their market capitalization – however, the maximum weighting is capped at 10% to ensure that major movements in one stock don’t have an exaggerated influence on the rest of the index’s performance. Along with HSBC and Tencent, other large constituents include the AIA insurance group, China Construction Bank, and the Industrial and Commercial Bank of China.
Hang Seng’s all-time low actually happened in 1967 – more than two years because the index officially launched. This was only made possible because the index was backdated by five years to 1964. Its all-time high came at the start of 2018, when it exceeded 33,000 points. These considerable rises coincided with a surge across global markets, and coincided with corporate tax cuts introduced by Donald Trump, as well as investment schemes that contributed to new flows of cash from mainland China.
