If you already invest in US or Singapore markets, the Hang Seng Index (HSI) is often the next place you look when exploring China and Hong Kong. The Hang Seng Index tracks many of the largest and most liquid companies listed in Hong Kong, including major Chinese tech, financial and consumer names. For Singaporean investors, a Hang Seng Index ETF is usually the simplest way to get diversified exposure to this market in a single trade.

In this guide, we’ll walk through what the Hang Seng Index actually is, how it’s constructed, how it has performed recently, and the main Hang Seng Index ETF options available. We’ll then zoom in on the practical bits for Singapore-based investors: how to buy a Hang Seng Index ETF from Singapore (HKEX vs SGX), what fees and risks to watch, how to position HSI in a broader portfolio, and when a Hang Seng ETF may or may not make sense.

By the end, you should have a clear, grounded view of how the Hang Seng Index works, how to invest in it via ETFs from Singapore, and how this exposure can fit into your long-term plan.

What Is the Hang Seng Index (HSI)?

The Hang Seng Index (HSI) is Hong Kong’s flagship stock market index. It is a free-float, market-capitalisation-weighted index that tracks the performance of the largest and most liquid companies listed on the Main Board of the Hong Kong Stock Exchange (HKEX).

As of October 2025, the Hang Seng Index includes 88 constituent companies, covering about 66% of the total market value of eligible Hong Kong stocks. It is compiled and maintained by Hang Seng Indexes Company Limited, a subsidiary of Hang Seng Bank.

For many global investors, the HSI is:

• A barometer for Hong Kong’s equity market, and
• A proxy for offshore China exposure, given the number of Chinese companies listed in Hong Kong.

When you buy a Hang Seng Index ETF, you’re essentially buying this whole basket of companies in one go.

Basic mechanics

Key features of the Hang Seng Index:

• Free-float adjusted – only shares that can actually be traded are counted, so large strategic or government holdings don’t distort the index.
• Market-cap weighted – bigger companies have a larger weight and move the index more.
• 8% capping rule – each constituent’s weight is capped at about 8% to avoid single-stock domination.
• Quarterly reviews – index membership and weights are reviewed regularly to keep HSI representative of the market.

For you as a Singapore investor, this means a Hang Seng Index ETF gives you built-in diversification across large-cap Hong Kong and China names, instead of a concentrated bet on one or two stocks.

Why the Hang Seng Index Matters for Singapore Investors

Gateway to China and Hong Kong

The Hang Seng Index is effectively a gateway to Greater China for investors who don’t want to deal directly with onshore A-shares.

• Many large Chinese tech, financial and consumer brands (such as Tencent, Alibaba, Meituan, JD.com, AIA, HSBC) are primary or secondary listed in Hong Kong and sit inside the index.
• Hong Kong is a key hub for Stock Connect, which channels mainland Chinese capital into Hong Kong-listed stocks and vice versa.

For a Singaporean investor who already holds STI ETFs and S&P 500 / Nasdaq ETFs, adding a Hang Seng Index ETF can:

• Increase China and North Asia exposure without opening onshore China brokerage accounts.
• Provide diversification away from a purely US-centric portfolio, while still staying within a familiar, well-regulated market.

Recent performance context (2024–2025)

After several weak years, Hong Kong equities have rebounded strongly:

• In the first half of 2025, the Hang Seng Index gained about 20%, outpacing many major indices.
• By late July 2025, HSI was up roughly 23.8% year-to-date, well ahead of the Shanghai Composite.
• As of 31 October 2025, official HSI data shows about +29% YTD and around +27–28% 1-year performance.

The iShares Core Hang Seng Index ETF (3115), which tracks the HSI Net Total Return Index, shows similar high-20s 1-year returns in HKD terms over the same period.

Mainland investors have also poured a record HK$800+ billion into Hong Kong via Stock Connect in 2025, helping to drive interest in Hang Seng ETFs.

This doesn’t guarantee future returns, but it explains why interest in hang seng index etf has picked up again—investors are reassessing Hong Kong after a long slump.

A different risk/return profile vs STI or S&P 500

Compared with the Straits Times Index (STI) and the S&P 500:

• Sector mix is different: HSI tilts more towards Chinese platforms and financials, and less towards US mega-cap tech or local Singapore banks.
• Currency is HKD, which is tightly managed against the USD. 
• Volatility has historically been higher than STI, closer to an emerging-markets profile because of China policy risk and global risk sentiment.

If you’re looking to tilt towards China/Hong Kong but don’t want to pick individual stocks, a Hang Seng ETF is a straightforward building block.

How the Hang Seng Index Is Constructed: Components & Sectors

Sector breakdown

The Hang Seng Index is broadly divided into major sectors such as:

• Financials – banks, insurers and exchanges (e.g. HSBC, AIA, HKEX)
• Information Technology / Communication Services – platform and internet companies (e.g. Tencent, Meituan, Xiaomi)
• Consumer & Retail – e-commerce, consumer discretionary and staples
• Properties & Utilities – Hong Kong property developers, utilities and infrastructure

The exact weights change over time, but in practice:

• Financials and tech/platform companies tend to dominate,
• With smaller weights in traditional property and utilities compared with the past.

If you’re researching Hang Seng Index components, it’s worth checking the latest sector and stock list on the official HSI website or your chosen ETF’s factsheet, as these are updated regularly.

From 4 sub-indexes to a broader benchmark

Historically, the HSI was divided into four key sector sub-indexes—Finance, Utilities, Properties, Commerce & Industry—and had fewer constituents. Over time, the methodology has been revamped to broaden coverage and ensure the index more accurately reflects Hong Kong and China’s evolving market.

Today, the modern index:

• Has 88 constituents (as of October 2025).
• Uses the 8% capping rule to avoid overweighting single names.
• Includes both Hong Kong-incorporated companies and mainland Chinese firms listed in Hong Kong.

What this means for Hang Seng Index ETFs

If you buy a Hang Seng Index ETF, you’re effectively owning a basket that:

• Skews towards large-cap China/HK financial and tech names,
• Has built-in diversification rules (free float, capping, regular review), and
• Is designed to cover roughly two-thirds of the HKEX market cap.

This structure is what a Hang Seng Index ETF will try to replicate as closely as possible.

Hang Seng Index Performance, Valuation & Volatility

Long-term perspective

Over multiple decades, the Hang Seng Index has gone through very distinct cycles:

• Strong compounding phases (for example, pre-2007, parts of the early 2010s, and rebounds after major sell-offs).
• Deep drawdowns during the Asian Financial Crisis, the Global Financial Crisis, US–China trade tensions, Covid, and the more recent tech and property crackdowns.

Historically, HSI has been more cyclical and more policy-sensitive than broad developed-market indices like the S&P 500. That’s why many investors classify a Hang Seng ETF as:

• A higher-volatility, higher-risk equity allocation, but
• Potentially offering higher expected returns when valuations are depressed and sentiment is overly negative.

Current valuation snapshot (late 2025)

According to the official HSI factsheet as of 31 October 2025:

• The HSI’s price-to-earnings (P/E) ratio is about 13.2 times.
• The dividend yield is roughly 3.1%, supported by Hong Kong and Chinese companies increasing payouts and buybacks in recent years.

The iShares Core Hang Seng Index ETF (3115), which tracks the HSI Net Total Return Index, reports similar valuation metrics and confirms a management fee of 0.09%.

Compared with many developed markets trading at higher P/E multiples, the Hang Seng Index looks cheap on a valuation basis, though this discount reflects the higher perceived risks.

Volatility and drawdowns

In return for lower valuations, you must accept larger price swings:

• The HSI has experienced multiple double-digit drawdowns in the last decade, often linked to regulatory moves, property-market stress, or trade tensions.
• The Hang Seng Tech Index has seen even sharper moves, at times dropping more than 30–40% before bouncing back.

If you’re considering a Hang Seng ETF, treat it as a medium- to high-risk equity allocation—not a bond or cash alternative.

Ways to Invest: Hang Seng Index ETFs and Alternatives

1. Hang Seng Index ETFs on HKEX

The most direct way to track the HSI is via HKEX-listed Hang Seng Index ETFs:

• iShares Core Hang Seng Index ETF (HKEX: 3115 / 9115)
  • Objective: Track the HSI Net Total Return Index via physical replication.
• CSOP Hang Seng Index ETF (e.g. HKEX: 3037)
  • Objective: Provide pre-fee performance that closely matches the Hang Seng Index.
• Tracker Fund of Hong Kong (TraHK, HKEX: 2800)
  • One of the oldest and most widely known HSI trackers; invests primarily in the constituent stocks of the Hang Seng Index in approximately the same weights as the index.

These are classic Hang Seng ETFs for investors comfortable trading in Hong Kong dollars via a broker that offers HKEX access.

2. Hang Seng-related ETFs on SGX

On the Singapore Exchange (SGX), you don’t get a pure Hang Seng Index ETF, but you do have access to Hang Seng-related index ETFs such as:

• Lion-OCBC Securities Hang Seng TECH ETF (SGX: HST / HSS) – seeks to replicate the Hang Seng TECH Index, which represents the 30 largest technology-themed companies listed in Hong Kong.

There are also SGX-listed ETFs tracking other Hang Seng Stock Connect indices and China leaders.

These aren’t pure Hang Seng Index ETFs, but they are popular with Singapore-based investors who want HK/China exposure in SGD or USD without going directly to HKEX.

3. Index funds and unit trusts

Hong Kong asset managers offer index funds (unit trusts) such as the Hang Seng Index Fund and the Hang Seng Index Tracking Fund, whose objectives are to closely track the HSI.

These can sometimes be accessed through banks and certain platforms in Singapore. However, for most retail investors, ETFs tend to offer lower ongoing fees and more transparent pricing.

4. Futures, CFDs and DLCs (for advanced traders)

More advanced investors can use instruments such as:

• HSI futures and options,
• Contracts for Difference (CFDs), and
• Daily Leverage Certificates (DLCs) on the HSI or Hang Seng TECH Index.

These products are short-term trading tools with leverage and path dependency. For most Singapore investors building long-term wealth, a simple Hang Seng Index ETF is more suitable than leveraged products.

How to Buy a Hang Seng Index ETF from Singapore (Step-by-Step)

Step 1: Choose your route – HKEX vs SGX

As a Singapore investor, you broadly have two routes:

1. HKEX route – Pure Hang Seng Index ETF
   • Buy Hang Seng Index ETFs such as 3115 (iShares Core Hang Seng Index ETF), 3037 (CSOP Hang Seng Index ETF) or 2800 (TraHK) directly on HKEX.
2. SGX route – Related Hang Seng index ETFs
   • Buy SGX-listed ETFs like Lion-OCBC Hang Seng TECH ETF (HST / HSS), which track Hang Seng sub-indices but not the main HSI.

If your goal is strict HSI tracking, the HKEX-listed Hang Seng Index ETFs are the most direct option.

Step 2: Open a broker that supports your route

Choose a broker that gives you access to HKEX and/or SGX. markets. Deposit SGD, then convert to HKD/USD inside the app if required. With Syfe Brokerage, it’s even simpler: Syfe’s auto-FX functionality converts your SGD to HKD/USD at order time to complete the trade — no extra manual conversion step required.

Step 3: Place your order smartly

Use a limit order during market hours so you control the price you pay.

Step 4: Automate your plan

Set up a recurring buy (weekly or monthly) to dollar-cost average. This keeps you consistent and removes the stress of timing the market.

Step 5: Monitor, but don’t overtrade

For long-term investors:

• Track dividends, expense ratios, and tracking difference between the ETF and the HSI.
• Keep an eye on China and Hong Kong policy developments, Hong Kong market liquidity, and global risk sentiment, as these can affect HSI volatility and performance.
• Avoid reacting purely to short-term headlines; focus on whether your original investment thesis for holding a Hang Seng ETF still holds.

Get Started

Hang Seng Index vs Other China & Asia Benchmarks

HSI vs Hang Seng TECH Index

The Hang Seng TECH Index (HSTECH) represents the 30 largest technology-themed companies listed in Hong Kong with high exposure to tech themes such as cloud, e-commerce, fintech and internet platforms.

• HSI – a broad Hong Kong/China benchmark with financials, property, utilities, consumer and tech.
• HSTECH – a concentrated tech and “new economy” index, more sensitive to tech regulation and sentiment.

If you only hold a Hang Seng Tech ETF, you don’t have full HSI exposure. Many Singapore investors blend:

• A core Hang Seng Index ETF for broad exposure, and
• A smaller “satellite” allocation to a Hang Seng Tech ETF for higher growth potential.

HSI vs MSCI China & CSI 300

• MSCI China includes a broad mix of China A-shares, H-shares and US-listed ADRs, giving more direct onshore exposure.
• CSI 300 focuses on the 300 largest A-shares on the Shanghai and Shenzhen exchanges.

Compared with these:

• The Hang Seng Index is more Hong Kong-centric and tilted towards offshore listings and Stock Connect-eligible names.
• Volatility drivers can differ (currency, regulation, offshore vs onshore capital flows).

For a Singapore investor building a China allocation, combining Hang Seng Index ETFs with broader MSCI China or onshore A-share ETFs can create a more balanced and diversified exposure.

Risks of Investing in Hang Seng Index ETFs

1. Geopolitical and policy risk

• Changes in China’s regulatory environment, especially around tech and property, can move the Hang Seng Index sharply in either direction.
• US–China tensions, tariffs and export controls can also weigh on sentiment, particularly for tech and export-oriented names.

2. Market and liquidity risk

• While the HSI itself is a large and liquid index, individual Hang Seng ETFs differ in liquidity. Always check bid/ask spreads, average daily turnover and fund size, especially if you’re considering smaller or newer ETFs.
• During stress events, spreads can widen and ETF prices may temporarily deviate from NAV.

3. Concentration and macro risk

Even with 88 stocks, the Hang Seng Index is:

• Heavily skewed towards financials and tech/platform companies, and
• Exposed to China’s macro and policy cycle more than Singapore or US-centric indices.

For this reason, treat a Hang Seng ETF as part of a diversified global equity mix, not your only international holding.

Who Should Consider Hang Seng Index ETFs (and How Much)?

Investor profiles that might fit

A Hang Seng Index ETF may be suitable if you:

• Already hold core global exposure (e.g. S&P 500, MSCI World, Asia ex-Japan ETFs) and want a targeted China/Hong Kong tilt.
• Have moderate to high risk tolerance and can stomach short-term volatility and drawdowns.
• Have an investment horizon of at least 5–10 years, to ride through policy and economic cycles in China and Hong Kong.

It may be less suitable if you:

• Need your money within the next 1–3 years,
• Prefer very low volatility, bond-like returns, or
• Already have heavy exposure to China or Hong Kong via your job, business or other investments.

Sizing in a portfolio (example for a Singapore investor)

For a diversified long-term Singapore investor, a purely illustrative allocation might look like:

• 40–60%: Global developed markets (e.g. world or S&P 500 ETFs)
• 10–20%: Home bias in Singapore (STI ETF)
• 10–20%: China / North Asia exposure, including
  • 5–10% in a Hang Seng Index ETF, and
  • Optional 5–10% in broader China or Asia ex-Japan ETFs

This isn’t a recommendation—just an example of how Hang Seng Index ETF exposure might sit alongside other holdings.

Practical Checklist When Choosing a Hang Seng Index ETF

When comparing Hang Seng ETFs (for example, 2800, 3115, 3037), consider:

1. Total Expense Ratio (TER)
   • Lower TER means less drag over time. For instance, iShares Core Hang Seng Index ETF charges a 0.09% management fee
2. Liquidity
   • Look at average daily turnover (how much the ETF trades each day), bid/ask spread (the gap between buy and sell prices), and assets under management (AUM) (the total size of the fund). Higher turnover, tighter spreads, and larger AUM generally mean the ETF is easier to trade and helps you get fair prices.
3. Replication method
   • Many major Hang Seng Index ETFs use physical replication, holding the underlying HSI stocks in similar weights. Such physical ETFs tend to offer clearer transparency and closer tracking of the index.
4. Distribution policy
   • Some funds distribute dividends, others may reinvest (accumulate). Choose based on whether you prefer cash flow or compounding.
5. Trading currency
   • Confirm whether you are trading in HKD, USD, RMB or SGD, and how that interacts with your base currency (SGD) and FX costs.

A small difference in fees, spreads and tracking error can compound significantly over time—especially if you plan to DCA into a Hang Seng Index ETF for 10–20 years.

Quick Takeaways

• The Hang Seng Index (HSI) is Hong Kong’s flagship equity benchmark and a common way to access China/HK stocks via a single index.
• A Hang Seng Index ETF (e.g. iShares Core Hang Seng 3115, CSOP Hang Seng Index 3037, Tracker Fund 2800) gives instant diversification across 88 large Hong Kong-listed companies.
• Singapore investors can access HSI via HKEX-listed ETFs (with HKD/FX considerations) or Hang Seng-related ETFs on SGX such as the Hang Seng TECH ETF.
• Valuations are currently relatively low and dividend yields around 3%, but volatility and policy risk are also higher compared with many developed markets.
• Treat a Hang Seng ETF as a medium- to high-risk equity component in a diversified portfolio, not a stand-alone bet or cash substitute.
• Key filters when choosing a Hang Seng Index ETF: fees, liquidity, replication method, distribution policy and trading currency.

Conclusion

For Singapore-based investors, the Hang Seng Index sits at an interesting intersection, offering direct exposure to Hong Kong’s capital market and many of China’s largest offshore-listed companies at valuations that are often cheaper than those of US or European peers. Through a Hang Seng Index ETF, you can capture this exposure in a simple, low-cost and diversified way, without needing to pick individual Chinese stocks or second-guess every policy headline.

The trade-off, however, is clear: higher volatility, higher uncertainty, and greater sensitivity to geopolitics and regulation. Market cycles in Hong Kong and China can be sharper and more sentiment-driven than in developed markets, which means that a Hang Seng ETF is best suited to investors who can stay invested for years, not months.

If you already hold global and Singapore equity building blocks and are looking to add a measured China/Hong Kong tilt, allocating a modest slice (for example, 5–10% of your equity portfolio) to a Hang Seng Index ETF can be a reasonable approach—provided it fits your risk profile and time horizon. Combine it with disciplined position sizing, regular rebalancing, and a clear understanding of FX and fee impacts, and the Hang Seng Index can play a useful role in a diversified, long-term strategy.

Frequently Asked Questions (FAQs)

1. What is the Hang Seng Index in simple terms?
The Hang Seng Index (HSI) is a stock market index that tracks a basket of large and liquid companies listed in Hong Kong, across sectors like finance, technology, consumer, property and utilities. When you buy a Hang Seng Index ETF, you’re effectively buying this basket through a single trade instead of purchasing each stock individually.

2. How can I invest in the Hang Seng Index from Singapore?
You can invest in the Hang Seng Index from Singapore in two main ways:

1. Buy a Hang Seng Index ETF on HKEX – for example, Tracker Fund of Hong Kong (2800), iShares Core Hang Seng Index ETF (3115) or CSOP Hang Seng Index ETF (3037) via a broker that offers Hong Kong market access.
2. Use SGX-listed ETFs that track related Hang Seng indices – such as the Lion-OCBC Hang Seng TECH ETF (HST/HSS), accepting that these are not pure HSI trackers.

In both cases, check trading fees, FX costs and minimum lot sizes before you invest.

3. Is a Hang Seng Index ETF suitable for beginners?
A Hang Seng Index ETF can be suitable for beginners if:

• It is used as part of a diversified portfolio, not as your only investment.
• You understand that HSI has higher volatility and policy risk than broad global indices like the MSCI World or S&P 500.

For many new investors, it’s sensible to build a core allocation to global or developed-market ETFs first, then add Hang Seng ETF exposure as a satellite position.

4. What are the main costs of investing in a Hang Seng Index ETF?

Typical costs for a Hang Seng Index ETF include:

• Fund-level fees (expense ratio / management fee) – for example, 0.09% for the iShares Core Hang Seng Index ETF.
• Brokerage commissions per trade.
• FX conversion costs when moving from SGD to HKD (or USD/RMB).
• Bid/ask spreads, which depend on ETF liquidity and market conditions.

Comparing these across different Hang Seng Index ETFs and brokers can help you keep your all-in cost low.

5. How does the Hang Seng Index differ from the Hang Seng TECH Index?
The Hang Seng Index is a broad market benchmark for Hong Kong, covering multiple sectors. The Hang Seng TECH Index focuses specifically on 30 large technology-themed companies listed in Hong Kong.

• HSI tends to be more diversified, with substantial weights in financials and other sectors.
• The Hang Seng TECH Index is more concentrated and volatile, heavily tied to Chinese tech sentiment and policy.

Many investors use an HSI ETF as the core holding and a Hang Seng Tech ETF as an optional growth satellite.
