Hang Seng chart
The Hang Seng Index tracks large companies listed on the Hong Kong Stock Exchange, maintained by Hang Seng Indexes Company. It is the leading benchmark for Hong Kong equities and a widely watched gauge of sentiment towards mainland China-linked businesses.
This page shows a CFD from OANDA, quoted in Hong Kong dollars, that tracks the Hang Seng's price movements, not the index itself, since the underlying index is not published as a free tradable feed on TradingView.

What is Hang Seng?
The Hang Seng Index is maintained by Hang Seng Indexes Company Limited and includes a selection of large, liquid companies listed on the Hong Kong Stock Exchange, spanning both Hong Kong-headquartered businesses and mainland Chinese companies listed in Hong Kong, commonly referred to as H-shares and red chips.
Constituents are weighted by float-adjusted market capitalisation, subject to a cap on the maximum weight of any single company. The index is reviewed quarterly, and its sector and company composition has shifted over time towards greater representation of mainland Chinese technology and financial firms.
The commonly quoted figure is a price-return index and excludes dividends; a total-return version is separately published. As with any index, the Hang Seng cannot be bought directly and is tracked through funds, futures or CFDs.
How to read this chart
A rising Hang Seng chart indicates that its constituents, weighted by free-float market capitalisation, have gained in aggregate; a falling chart indicates the opposite.
Because a substantial share of constituents are mainland Chinese companies, the index is often influenced as much by mainland Chinese policy and economic conditions as by conditions specific to Hong Kong itself.
The chart shown here is a CFD proxy quoted in Hong Kong dollars and can diverge slightly intraday from the official index due to the provider's own pricing; the Hong Kong dollar's peg to the US dollar means it does not introduce the same independent currency variability seen in some other regional benchmarks.
What moves it?
- Mainland Chinese economic policy
- Because many constituents are mainland Chinese companies, Beijing's regulatory, fiscal and monetary policy decisions have a direct and often significant effect on the index.
- Chinese property sector conditions
- Property developers and related financial companies have historically carried meaningful weight, making the index sensitive to conditions in China's real-estate sector.
- Technology-sector regulation
- Large mainland Chinese technology companies listed in Hong Kong are sensitive to Chinese regulatory actions affecting the technology and platform sectors.
- US-China relations
- Trade policy, export controls and broader geopolitical tension between the US and China can affect sentiment towards Hong Kong- and China-linked equities.
- Hong Kong dollar peg and capital flows
- The Hong Kong dollar's peg to the US dollar links local interest-rate policy to US rates, while cross-border capital-flow rules affect liquidity available to the market.
Why businesses and investors monitor it
Businesses trading with mainland China or Hong Kong use the Hang Seng as an indicator of sentiment towards Chinese economic and regulatory conditions, given the heavy representation of mainland companies in the index.
Investors use it as a benchmark for Hong Kong- and China-linked equity exposure, distinct from mainland China's own domestically listed A-share indices.
Hang Seng vs Nikkei 225
The Hang Seng is dominated by Hong Kong- and mainland China-linked companies and is capitalisation-weighted, while the Nikkei 225 tracks Japanese exporters and is price-weighted.
The Hang Seng tends to respond more to Chinese policy, property-sector conditions and regulatory news, while the Nikkei 225 is more sensitive to yen exchange-rate moves and global export demand.
Frequently asked questions
Does the Hang Seng only include Hong Kong companies?
No. It includes a mix of Hong Kong-headquartered businesses and mainland Chinese companies listed in Hong Kong, and mainland-linked constituents represent a substantial share of the index's weight.
Is the Hang Seng the same as mainland China's stock market indices?
No. Mainland China's domestically listed A-shares are tracked by separate indices such as the CSI 300; the Hang Seng specifically covers companies listed on the Hong Kong Stock Exchange.
Why is a CFD shown instead of the index?
The official Hang Seng index feed is not offered as a free TradingView symbol, so this page uses a CFD from OANDA, quoted in Hong Kong dollars, that closely tracks its price movements.
How often is the Hang Seng reviewed?
Hang Seng Indexes Company reviews the index quarterly, adjusting constituents and weights based on updated market-capitalisation and liquidity data.
