Hang Seng Index
The Hang Seng Index ("HSI") is one of the earliest stock market indexes in Hong Kong. Publicly launched on 24 November 1969, the HSI has become the most widely quoted indicator of the performance of the Hong Kong stock market.
The HSI is a broad-based, modified-free-float-adjusted market-capitalization-weighted index designed to reflect the performance of the overall Hong Kong stock market.
Futures and options on the Hang Seng Index (HKFE Hang Seng Index Futures) are offered on the Hong Kong Futures Exchange. In January 2009, The Commodity Futures Trading Commission approved Hong Kong Futures Exchange's mini futures contracts based on the Hang Seng Index (HSI) and the Hang Seng China Enterprises Index (HSCEI), for trade in the U.S.
