HKEX Hang Seng Index Futures
Trade Hong Kong's benchmark equity index on the Hong Kong Futures Exchange.
Hang Seng Index (HSI), the benchmark of the Hong Kong stock market, is one of the best known indices in Asia and is widely used by fund managers as their performance benchmark. The HSI is a market capitalisation-weighted index — shares outstanding multiplied by stock price — of the constituent stocks, grouped under Commerce and Industry, Finance, Properties and Utilities sub-indices. Constituent stocks with higher market capitalisation carry greater influence on the index's performance than those with lower market capitalisation.
To meet the growing interest in the Hong Kong stock market and the rising demand for related hedging tools, the Hong Kong Futures Exchange (HKFE) first introduced HSI futures contracts in May 1986. HSI futures and options provide investors with a set of effective instruments to manage portfolio risk and to capture index arbitrage opportunities, and have grown in popularity alongside increasing domestic and international investor participation.

To meet the needs of retail investors with an interest in the Hong Kong stock market, the Hong Kong Futures Exchange (HKFE) introduced Mini-Hang Seng Index (Mini-HSI) Futures on 9 October 2000, complemented by Mini-HSI Options launched on 18 November 2002.
The compact Mini-HSI contracts are based on the same benchmark Hang Seng Index (HSI) underlying the larger HSI futures and options, carrying a contract multiplier of HK$10.00 — one-fifth the size of the HSI contracts — and are cash-settled in the same way. Local retail investors with less risk capital and lower hedging requirements will find Mini-HSI futures and options the most appropriate investment and hedging tools for managing their market risk.
Key Benefits
- Tailor-made for Retail Investors
- The Mini-HSI futures and option contracts inherit the advantages of the larger sized HSI contracts but are tailored for individuals with limited risk capital. The smaller contract size allows experienced and novice investors alike to participate in the performance of the constituent stocks in the index on a graduated scale.
