What is the Hang Seng Index?
The Hang Seng Index, abbreviated as HSI, is an index of the largest companies traded on the Hong Kong Exchange. The breakdown of the index is weighted based upon the market capitalization of the underlying companies. Each underlying company is sub-categorized into commerce and industry, utilities, finance, and properties. This allows for greater analysis of the index performance. The Hang Seng index includes approximately 65% of the total market capitalization of all companies traded on the index.
