After my earlier piece, My Investment Memoirs, I received many questions from readers who wanted more exposure to US equities and less reliance on A-shares and Chinese ADRs.
For ordinary investors without deep financial knowledge, my answer is usually straightforward.
You live in mainland China. Your income is earned there. Your savings are mainly held in onshore bank accounts, and most of your assets are denominated in renminbi.
So the practical question is not what the theoretically optimal global portfolio looks like.
The practical question is how to use channels that are already available to you to build long-term S&P 500 and Nasdaq exposure in a compliant, repeatable way.
The conclusion is simple. The S&P 500 and Nasdaq remain attractive long-duration assets, but current valuations are not cheap. Much of the recent US rally has been driven by AI, semiconductors, and a handful of mega-cap technology companies. If inflation reaccelerates or rate cuts are delayed, technology valuations could come under pressure. That does not mean avoiding the market entirely. It means avoiding an all-in entry after a strong run. For most mainland investors, QDII remains the most practical route: off-exchange funds work well for regular contributions, while onshore-listed ETFs can be useful when their premiums are reasonable.
Do you need a Hong Kong bank account first? Do you need an offshore broker?
For most mainland investors, neither is the first step.
Start with channels you already use: Alipay, your banking app, your brokerage app, and fund-company direct platforms. The products available through these channels are mainly QDII funds.
Search for “Nasdaq” or “S&P” in Alipay or a major banking app and you will usually find several products. They may not be the cheapest or the most flexible, but they are often the simplest place to begin.
The banking channel is especially easy to overlook. A fund that has reached its purchase limit on one platform may still have quota elsewhere. If Alipay is restricted, a bank, brokerage, or the fund company’s own platform may still be accepting subscriptions.
The important questions are practical: can you buy the product, what is the purchase limit, what are the fees, how long does redemption take, and what index or asset class does it actually track?
For most investors, the first objective is not finding the perfect product. It is finding a simple route that can be used consistently for years.
QDII allows an onshore investor to buy a domestic fund that uses regulator-approved quota to invest overseas. Depending on the product, the fund may track the S&P 500, Nasdaq 100, US technology stocks, or offshore ETFs.
You do not need to convert currency yourself, open an offshore brokerage account, or arrange the cross-border remittance. The fund manager handles those steps within the QDII framework.
That makes QDII a practical bridge between onshore renminbi savings and offshore market exposure.
The drawbacks are real. Fees can be higher than those of US-listed index ETFs, quota can tighten, popular funds may impose purchase limits, tracking error can be meaningful, and onshore-listed QDII ETFs can trade at large premiums.
Its main advantage is equally clear: it operates within an established onshore framework. For ordinary mainland investors who want long-term US index exposure, that simplicity matters.
Off-exchange QDII refers to funds bought through platforms such as Alipay, banking apps, or fund-company platforms. They are well suited to investors who do not want to monitor intraday prices. You can contribute regularly and build a position over time without watching an order book or tracking ETF premiums every day.
The main advantage is simplicity: low minimums, familiar interfaces, and easy recurring purchases. The main disadvantages are slower subscriptions and redemptions, slower settlement, potentially higher fees, and purchase limits. Some products may restrict daily subscriptions to very small amounts, in which case larger purchases may require another channel.
If the goal is simply to build S&P 500 or Nasdaq exposure over time, off-exchange QDII is usually sufficient. Smaller accounts in particular do not need to optimize every detail from day one. Consistency and entry discipline matter more.
Many investors look only at Alipay, but long-term QDII buyers should also compare bank platforms.
QDII products operate under quota, and availability can differ by distribution channel. A purchase restriction on one platform does not necessarily mean the fund is unavailable everywhere. Banks, brokers, or the fund company’s direct platform may still have capacity.
This matters more for larger accounts. Bank channels may also offer different subscription limits, redemption arrangements, cash-management options, and customer service. They are not automatically cheaper, however, so fees still need to be checked carefully.
Before buying, make sure you can answer three questions clearly: what index does the product track, what is the all-in cost, and how much can you actually buy?
Onshore-listed QDII ETFs are cross-border ETFs traded through an A-share brokerage account. They include Nasdaq, S&P 500, and overseas technology products.
Their main advantage is flexibility. They trade intraday, some allow T+0 trading, and investors can control the execution price directly.
The main risk is the premium to net asset value. If an ETF’s underlying value is 100 but strong demand pushes its market price to 105, the investor is paying a 5% premium. Even if the Nasdaq itself does not fall, the ETF can lose value if that premium later compresses.
Premiums often widen when US equities are rallying and mainland demand is strongest, which is exactly when investors are most tempted to chase. My conservative rule of thumb is to pay close attention below a 3% premium and become much more cautious above 5%. Investors using regular contributions may tolerate more variation, but premium risk should still be part of the decision.
Opening a Hong Kong bank account can be useful for legitimate cross-border needs such as travel, study, work, spending, or receiving payments. It does not automatically make direct US-stock investing appropriate for every mainland investor.
Banks and brokers may apply additional scrutiny to mainland clients, and the practical question is not simply whether an account can be opened. Investors also need to consider the source of funds, the purpose of transfers, foreign-exchange rules, investment-account reviews, and potential tax obligations.
If your savings are primarily onshore renminbi salary and deposits, do not assume that opening a Hong Kong account removes those considerations. A Hong Kong bank account is a useful financial account, not a substitute for understanding the rules that apply to the money moving through it.
I will leave this category as an area for further research rather than treat it as a mainstream route. Investors considering it should understand the product structure, custody, regulatory status, liquidity, and counterparty risk before using it.
Under RMB 100,000: prioritize simple off-exchange QDII products through Alipay, banks, or fund platforms. The goal is to begin regular investing without overcomplicating the setup.
RMB 100,000–500,000: off-exchange QDII can remain the core, with some onshore-listed ETF exposure if you understand and monitor premiums.
Above RMB 500,000: compare multiple distribution channels. For off-exchange funds, focus on purchase limits and fees. For onshore ETFs, pay attention to liquidity and premiums. As account size grows, reducing frictional costs becomes more important.
For mainland investors seeking S&P 500 or Nasdaq exposure, QDII remains the main practical route discussed here. Alipay and bank platforms are usually the easiest starting points. Off-exchange QDII works well for long-term recurring investments, while onshore-listed QDII ETFs can suit investors who understand premium risk.
Hong Kong bank accounts can be useful, but they should not be treated as a shortcut around foreign-exchange, source-of-funds, investment-account, or tax considerations. Full-equity RWA products are worth monitoring, but they are not presented here as a mainstream route for mainland investors.
The goal is not to find the most exciting or theoretically highest-return channel. It is to find a route that is compliant, stable, understandable, and sustainable over the long run.
