Hong Kong Stock Exchange: Complete Guide to HKEX
The Hong Kong Stock Exchange is one of the most international markets in Asia: a crossroads where Chinese giants (Tencent, Alibaba, Meituan) meet global banks (HSBC) and mainland insurers. Its flagship index, the Hang Seng, is one of the most closely followed in the world, and one of the most volatile among major markets, pulled between Chinese growth and geopolitical tensions. This page covers the Hong Kong Stock Exchange from A to Z: structure, indices, trading hours in French time, leading stocks, access from France and specific risks.
What Is the Hong Kong Stock Exchange (HKEX)?
The Hong Kong Stock Exchange belongs to HKEX (Hong Kong Exchanges and Clearing), the listed group that runs the equity market, derivatives and London metals trading through the London Metal Exchange, acquired in 2012. The market’s history dates back to 1891, when the Association of Stockbrokers in Hong Kong formalized trading; the modern stock exchange was born from mergers in the 1980s to 2000s and the 2000 demutualization, which made HKEX itself a listed company.
Two features set Hong Kong apart from other major Asian markets. First, its role as the gateway for international capital into China: large mainland groups have their primary or secondary listing there, and the Stock Connect programs link the market directly to the Shanghai and Shenzhen exchanges. Second, its legal framework, inherited from British common law, which long made Hong Kong the favorite IPO venue for Chinese companies, although this status has become more nuanced as regulation has tightened on both sides of the border.

The Hang Seng and the Market’s Other Indices
The Hang Seng Index (HSI)
The Hang Seng Index is the Hong Kong Stock Exchange’s benchmark: around 80 of the market’s largest companies, weighted by free float, spread across finance, technology, property, commerce and energy. Its volatility is famous: the index has seen decades of spectacular returns, then years of rout linked to Chinese crises, the 2019 protests and Beijing’s regulatory crackdown on tech from 2021. Our dedicated Hang Seng page details its composition and calculation.
The Hang Seng China Enterprises Index (HSCEI)
The HSCEI groups mainland companies listed in Hong Kong (“H shares” and “red chips”): it is the index that gives the most direct exposure to mainland China via Hong Kong. Big names in Chinese banking, oil and technology dominate it, and it is more closely correlated with Beijing’s industrial policy than the HSI.
The Hang Seng TECH Index
Launched in 2020, the Hang Seng TECH index groups around thirty technology stocks listed in Hong Kong: e-commerce platforms, video games, fintech, digital health and electric vehicles. It is one of the most volatile tech indices in the world: China’s regulatory campaigns of 2021-2022 wiped out years of performance in a few months, before an equally sharp rebound.
Hong Kong Stock Exchange Hours in French Time
The Hong Kong Stock Exchange is open Monday to Friday in two sessions: 9:30 am – 12:00 pm and 1:00 pm – 4:00 pm Hong Kong time (UTC+8). The time difference with Paris is 6 hours in winter as in summer (both shift their clocks for summer time). As a result, Hong Kong opens at 3:30 am Paris time and closes at 10:00 am: the French morning coincides with the end of the Hong Kong session, making it an Asian market that is easier to follow from Europe than Tokyo. A pre-opening session precedes the morning, and the market closes for Chinese holidays, including Lunar New Year, sometimes for long periods. Detailed Hong Kong Stock Exchange hours, including public holidays, are listed on our dedicated page.

The Hang Seng’s composition mixes local champions and mainland giants:
| Company | Sector | Key Facts |
|---|---|---|
| Tencent | Internet, video games | Social media and online gaming giant (WeChat), usually the market’s largest company by capitalization. |
| Alibaba | E-commerce, cloud | China’s number one in e-commerce, listed in Hong Kong and New York. |
| HSBC | Banking | Hong Kong’s largest bank, a group present in Asia, Europe and the Middle East. |
| AIA Group | Insurance | Asia’s leading life insurer, listed exclusively in Hong Kong. |
| Meituan | Delivery, local services | Chinese delivery and everyday services platform, a heavyweight in the Hang Seng TECH. |
| China Mobile | Telecoms | Mainland telecom operator, a “defensive” stock in the HSCEI. |
| BYD Company | Automotive, batteries | China’s electrified vehicle champion, also listed in Shenzhen. |
This table shows the market’s two faces: companies with global revenues (HSBC, AIA) and others entirely dependent on the Chinese economy (Tencent, Meituan, BYD). An investor in the Hong Kong Stock Exchange is really buying hybrid Asia-China exposure.
How to Invest in the Hong Kong Stock Exchange from France
Hang Seng and China ETFs Listed in Europe
European ETFs tracking the Hang Seng, the HSCEI or the Hang Seng TECH trade in Paris in euros, with the fees of an index fund. Most are PEA-eligible (Europe-domiciled funds), making them the simplest route to index exposure. Watch out for tracking quality on volatile indices and for Hong Kong dollar/euro currency risk: the HKD has been pegged to the US dollar since 1983, so the exposure resembles a dollar-euro bet backed by equities.
Buying Hong Kong Shares Directly
Buying Tencent or HSBC directly in Hong Kong requires a brokerage account with a broker covering Asian markets. Access fees, HKD conversion and price differences between markets (the same company is sometimes listed in Hong Kong, New York and Shenzhen) require some preparation. The fundamentals are in our guide on how to invest in the stock market, and our Vantage review looks at a broker offering access to major international markets.
CFDs and Certificates
CFDs on the Hang Seng and major Hong Kong stocks let you trade the index with leverage and almost around the clock. The usual warnings apply: leverage amplifies losses, most retail CFD accounts lose money, and the Hang Seng’s structural volatility makes this market particularly demanding in terms of risk management. For the difference between owning shares and trading CFDs, our comparison page explains both approaches.
The Link with Mainland China: Stock Connect and H Shares
A major feature of Hong Kong: the Stock Connect programs let international investors buy Shanghai-listed shares through their Hong Kong account (Northbound), and mainland investors buy Hong Kong stocks (Southbound). This bridge makes the Hong Kong Stock Exchange the preferred hub for investing in mainland China. To understand the full structure of Chinese markets (A shares, B shares, STAR Market), see our page on the Chinese stock market.
Risks of the Hong Kong Stock Exchange
Risks on this market are not just for show. Chinese regulatory risk showed in 2021-2022 that a decision by Beijing can wipe out tens of percent of market capitalization across an entire sector in a few months. Geopolitical risk, from US-China tensions and the city’s status to sanctions, weighs on valuations repeatedly. Currency risk (HKD pegged to the USD, so indirect dollar exposure) and delisting risk for groups also listed in the United States complete the picture, with liquidity that can dry up very quickly in times of stress. Hong Kong is a market of big cycles: those who invest there must accept swings that neither Wall Street nor the Paris Stock Exchange deliver.
Hong Kong Stock Exchange FAQ
