When you follow the Hang Seng Index and decide to put money to work, choosing the right ETF is critical. For most investors who focus on “long-term holding” and “cost control,” the answer is clear: 3115 iShares Core Hang Seng Index ETF is the top choice.
Core reason: It has the lowest total expense ratio (TER) among the three, meaning your long-term investment costs are effectively minimized.
However, the lowest cost isn’t ideal for everyone. Your trading frequency and capital size will also influence the final decision.

Establishing the right market mindset before committing capital is extremely important. This helps you understand why ETFs that track the Hang Seng Index are the preferred choice for many investors.
The Hang Seng Index represents the overall performance of the Hong Kong stock market and serves as a thermometer for market sentiment. When you believe the Hang Seng Index is at a low point or has upside potential, “buying the entire market” becomes a highly efficient strategy. ETFs (Exchange-Traded Funds) are the perfect tool to achieve this goal.
ETFs make investing much simpler, offering these main advantages:
- Time & effort saving: No need to dig into individual company reports—just focus on the big-picture direction of the index.
- Flexible trading: ETFs trade like stocks on the exchange, allowing you to enter or exit anytime.
- Cost advantage: Buying and selling Hong Kong ETFs is exempt from stamp duty, saving you transaction fees.
- High transparency: Fund companies publish holdings daily, so you always know exactly where your money is invested.
In short, ETFs give you the convenience of trading a single stock while achieving diversification across a basket of blue-chip companies.
All three ETFs aim to track the Hang Seng Index, but their backgrounds and characteristics differ—like athletes with different strengths.
Once you understand their basic backgrounds, you can more easily decide which one best fits your Hang Seng Index investment plan based on their data.

Data is objective and helps you cut through market noise to make rational decisions. We will analyze the pros and cons of these three ETFs across five core metrics.
Quick Overview: Key Data of the Three HSI ETFs
Metric 2800 Tracker Fund 3115 iShares Core 2833 Hang Seng Index ETF Total Expense Ratio (TER) ~0.08% ~0.07% (lowest) ~0.10% Cost per Board Lot ~HK$8,500 (highest) ~HK$850 (lowest) ~HK$8,500 Avg. Daily Volume Extremely high (best liquidity) Lower Medium Tracking Error Very low Very low Very low Dividend Frequency Semi-annual Semi-annual Semi-annual Note: The above figures are approximate. Actual fees and prices fluctuate with the market. Please refer to the latest exchange announcements before trading.
From the table, you can quickly see that each has clear strengths and weaknesses. Next, we dive deeper into the details of each option.
If your top priority is “being able to buy and sell quickly anytime,” then 2800 is undoubtedly your first choice.
Who should choose 2800?
If you are a short-term trader who frequently enters and exits the market, or an institutional investor with large capital who values liquidity above all, 2800’s advantages are irreplaceable.
If you are a long-term investor looking 10 or 20 years ahead, every cent of cost matters.
The key to winning in long-term investing
Assuming a 10-year horizon, a mere 0.03% annual fee difference means your portfolio will grow noticeably more thanks to lower costs. Money saved is money earned—this is an iron rule in long-term investing.
If you want a middle ground between “trading convenience” and “holding cost,” 2833 is worth considering.
Who should consider 2833?
If you plan to hold for the medium-to-long term but still want some trading flexibility without paying 2800’s relatively higher fees, 2833 offers a solid balanced solution. It gives you one more moderate choice when planning your Hang Seng Index strategy.
After understanding the data differences, the key is to match these metrics with your own investment objectives. Your view on the Hang Seng Index trend and your investing habits will directly determine the best ETF for you. Below are clear recommendations for three common scenarios.
Important note: Although these ETFs are traded on the Hong Kong Stock Exchange (HKEX) in HKD, all currency values in this article are approximated in USD for consistency. Actual amounts will vary with exchange rates.
If you are investing for the next decade or two with the goal of building wealth through long-term holding, “cost” is your most important decision factor.
Clear choice: 3115 iShares Core Hang Seng Index ETF
Action suggestion: If you plan to invest a fixed amount monthly or quarterly and hold long-term, choosing 3115 will maximize your potential returns.
If your strategy involves short-term trades based on market swings or you manage large capital as an institution, “liquidity” overrides everything else.
Clear choice: 2800 Tracker Fund
Action suggestion: If you trade frequently or move large sums, choose 2800 to ensure smooth execution. You can use platforms like Biyapay to quickly convert and transfer funds, giving you maximum flexibility to seize trading opportunities.
If you’re just starting out or can only invest a small amount each month, “entry threshold” is what you care about most.
Clear choice: 3115 iShares Core Hang Seng Index ETF
Action suggestion: For retail investors or beginners, 3115 is the friendliest option. Platforms like Biyapay make it easy to transfer small amounts and start buying with almost no pressure.
In summary, there is no absolute “best” ETF—only the one that best matches your current strategy. Choose wisely based on your capital size, trading frequency, and investment horizon.
Now you can make a clear decision based on your goals. Here is our final recommendation:
Remember, there is no universally best ETF—only the one that best fits your personal strategy. Make the smartest choice based on your needs.
All three ETFs distribute dividends regularly, usually semi-annually. The dividends you receive come from the underlying Hang Seng Index constituent companies. You can choose to reinvest dividends to accelerate wealth growth.
Tracking error is the difference between an ETF’s return and its benchmark index (Hang Seng Index). All three ETFs have extremely low tracking error, meaning they replicate the index performance very accurately. Therefore, this factor has minimal impact on your long-term returns.
Directly buying all constituent stocks requires huge capital and complicated transactions. ETFs let you own a diversified basket at a fraction of the cost—making it a far more efficient choice for most investors.
Under current Hong Kong tax law, trading HKEX-listed ETFs is exempt from stamp duty, and both capital gains and dividend income are tax-free. This keeps the overall tax burden very low for ETF investors.
