HANG SENG

The Hang Seng Index (HSI) is the primary benchmark of the Hong Kong stock market and one of the most important equity indices in Asia. It tracks the performance of major companies listed on the Hong Kong Stock Exchange (HKEX), many of which are closely linked to China’s economy.
For global investors including those in India the Hang Seng Index serves as a key gateway to China exposure, Asian markets, and global trade trends, making it a closely watched index worldwide.

What is the Hang Seng Index?

The Hang Seng Index, commonly referred to as HSI, represents the performance of large, liquid companies listed in Hong Kong. It is designed to reflect the overall performance of the Hong Kong equity market.

Due to Hong Kong’s role as a financial hub, the Hang Seng Index attracts significant global investor interest.

History of the Hang Seng Index

The Hang Seng Index was launched in 1969, making it one of the oldest stock market indices in Asia. It was created to provide a clear and reliable measure of the Hong Kong stock market’s performance.

Over the decades, the index has evolved to reflect:

• Hong Kong’s growth as an international financial centre
• Increasing participation of mainland Chinese companies

Changing sector dynamics, especially in technology and financial services

How Does the Hang Seng Index Work?

The Hang Seng Index is a free-float market capitalisation–weighted index, meaning:

• Companies with higher market capitalisation have a greater impact on index movements

This methodology ensures that the index accurately reflects the performance of Hong Kong’s most influential stocks.
