Hong Kong Stock Exchange (HKEX) — Gateway to Chinese Markets
How HKEX Works
HKEX runs a fully electronic, order-driven trading system. The exchange hosts two boards: the Main Board for established companies and the Growth Enterprise Market (GEM) for smaller, earlier-stage businesses. Hong Kong’s regulatory framework, based on English common law, provides a familiar legal structure for international investors — a key reason why many Chinese tech giants choose to list there rather than on mainland exchanges.
What sets HKEX apart is Stock Connect, launched in 2014 with Shanghai and expanded to Shenzhen in 2016. This cross-border mechanism lets international investors buy mainland Chinese stocks through Hong Kong, and vice versa, without needing separate brokerage accounts in each market.

The Hang Seng Index
The Hang Seng Index (HSI) is Hong Kong’s most-watched benchmark, tracking around 80 of the largest companies listed on HKEX. It is heavily weighted toward financials (HSBC, AIA) and Chinese tech (Tencent, Alibaba, Meituan). The Hang Seng Tech Index, launched in 2020, focuses specifically on the 30 largest tech companies — think of it as Hong Kong’s answer to the Nasdaq Composite.
Why HKEX Matters for Global Investors
Hong Kong is the world’s top IPO market in many years, attracting huge listings from Chinese companies like Alibaba, JD.com, and Xiaomi. In 2018, HKEX reformed its listing rules to allow dual-class share structures and pre-revenue biotech companies to list — changes that drew a wave of tech and healthcare IPOs. For investors wanting China exposure without navigating mainland restrictions, HKEX is the most accessible route.
