Overview

The Hang Seng Index (HSI) is the flagship stock market index of the Hong Kong Stock Exchange (HKEX), tracking the performance of the largest and most liquid companies listed in Hong Kong. Comprising 50 key blue-chip companies, the HSI offers a clear picture of the broader Hong Kong economy while also serving as a proxy for investment sentiment toward mainland China.

Established in 1969, the HSI is one of Asia’s most followed equity indices and a vital benchmark for fund managers, ETFs, and institutional investors globally. The index includes a mix of financial institutions, real estate conglomerates, and increasingly, technology and innovation companies such as Tencent, Alibaba, and Meituan. Many of its constituents are either directly or indirectly connected to mainland China’s economy, making the HSI a strategic index for those seeking exposure to Chinese growth within a more open and international regulatory framework.

As a highly liquid index traded by global investors, the Hang Seng Index reflects shifts in risk sentiment, global monetary policy, and macroeconomic data from China and Hong Kong. It is a central component of Asia-Pacific trading strategies and often moves in response to both domestic events and broader geopolitical developments.
