Hong Kong stocks and mainland China A-shares are listed in different markets and operate under different access, currency, trading and settlement rules. Overseas investors can buy some A-shares through Northbound Stock Connect, but eligibility depends on the investor, intermediary and individual security. Stock Connect is a limited route into selected securities—not unrestricted access to every mainland listing.
What is the difference between A-shares and Hong Kong stocks?
A-shares are mainland-listed securities, including shares listed on the Shanghai Stock Exchange (SSE) and Shenzhen Stock Exchange (SZSE). Hong Kong stocks are listed on the Stock Exchange of Hong Kong (SEHK). The company’s nationality does not determine which market a particular share trades in: check the listing and security, not just the issuer’s identity.
Stock Connect links the markets through connected exchange and clearing systems. Shanghai Connect began in November 2014 and Shenzhen Connect in December 2016. The programme lets eligible investors trade designated securities across the border, but it does not make the markets interchangeable.

Can foreigners buy China A-shares?
Yes, Hong Kong and overseas investors can trade selected Shanghai and Shenzhen A-shares through Northbound Stock Connect, subject to eligibility rules. Not every A-share is included, and some board-specific shares are restricted. Northbound access also covers eligible ETFs, not every product listed on the mainland exchanges.
#1 Best Overall
Which shares can be accessed?
- For Shanghai Connect, HKEX says selected SSE main-board securities are available to eligible Hong Kong and overseas individual and institutional investors. STAR Market shares are restricted to institutional professional investors.
- For Shenzhen Connect, selected SZSE securities are open to eligible Hong Kong and overseas individual and institutional investors; ChiNext shares are restricted to institutional professional investors.
- Eligibility is security-specific and can change. Check the live Stock Connect eligibility list for the exact share or ETF before placing an order.
The SSE’s eligibility criteria illustrate why a listing alone does not guarantee access. For relevant SSE A-share constituents, criteria displayed on its eligibility page as accessed on 7 October 2026 include average daily market value of at least RMB 5 billion and average daily turnover of at least RMB 30 million over the stated six-month period. These are criteria for relevant securities, not a minimum account balance or a universal rule for every Connect share. For eligible Northbound ETFs, the displayed criteria include average assets under management of at least RMB 500 million over six months and at least six months of listing.
What Stock Connect does not provide
Stock Connect is a secondary-market trading route, not a way to subscribe to IPOs. Northbound trading is also subject to daily quotas, so access is not an unconditional guarantee that an order can be placed or filled.
How do I buy China A-shares through Stock Connect?
- Confirm your broker supports Northbound Stock Connect. Availability, account requirements and order handling depend on the intermediary. A standard brokerage account does not necessarily include Connect access.
- Check the specific security. Search the current Shanghai or Shenzhen eligibility list, and confirm that your investor category can trade that board. Eligibility may differ between main-board shares, STAR, ChiNext and ETFs.
- Review currency and charges before trading. Northbound SSE A-shares are traded and settled in renminbi (RMB). Ask how your broker handles RMB funding or conversion, and check its own commissions and conversion charges.
- Place an order through your broker’s Connect service. The broker routes eligible orders into the connected market. Trading rules, order availability and daily quotas apply; consult the broker’s instructions for accepted order types and cut-off times.
- Check the resulting position and settlement details in your account. The route uses connected exchange and clearing arrangements, so the account’s display and settlement treatment may differ from a domestic Hong Kong shareholding.
How do the markets differ in practice?
| Factor | Mainland A-shares through Northbound Stock Connect | Hong Kong-listed shares |
|---|---|---|
| Listing venue | Selected A-shares listed on the SSE or SZSE | Shares listed on the SEHK |
| Investor access | Eligible securities only; investor, intermediary and board restrictions apply | Access depends on the investor’s broker and the security |
| Currency | Northbound SSE A-shares trade and settle in RMB, according to the SSE | Trading currency is the one specified for the particular listing, commonly HKD; verify the security details |
| Price limits | HKEX’s October 2024 Stock Connect booklet describes general daily limits of ±10%, with ±20% for ChiNext and STAR shares and selective ETF exceptions | The 2017 IFEC comparison reports no equivalent daily price limit for Hong Kong shares; verify current rules for the particular security |
| Tax and market charges | Mainland exchange and settlement charges can apply; Hong Kong’s IRD says Northbound SSE/SZSE trades are not subject to Hong Kong stamp duty | Hong Kong-market taxes and charges follow Hong Kong rules and can depend on the transaction and security |
| Disclosure language | The 2017 IFEC comparison describes mainland announcements as Simplified Chinese | The 2017 IFEC comparison describes Hong Kong announcements as Traditional Chinese and English |
The table’s dated IFEC comparisons are from 7 December 2017 and should not be treated as confirmation of current operational or disclosure rules. HKEX’s October 2024 booklet is the source for the stated price-limit figures; check current exchange rules for the specific board and security.

RMB exposure is separate from share-price movement
A Northbound A-share’s price and settlement are in RMB. If your account is funded in another currency, your return in that home currency can therefore reflect both the share’s price movement and exchange-rate changes. The conversion rate, timing and charges depend on your broker and account; they are not captured by the share’s quoted price.
Rank #3
Do not assume settlement rules are the same
Mainland trading and settlement arrangements differ from Hong Kong’s. IFEC’s 7 December 2017 comparison described a T+1 restriction on selling mainland shares and T-day share/T+1 money settlement, while describing T+2 settlement for Hong Kong shares. Those are historical descriptions, not reliable current instructions. Confirm current sale availability and settlement timing with your broker and the relevant exchange or clearing rules.
Custody and disclosure details need current verification
The same 2017 IFEC comparison described Connect A-shares as held in a scripless arrangement through HKSCC as registered shareholder, and discussed foreign ownership caps and shareholding disclosure thresholds. Because those details may have changed, do not rely on that page for current nominee arrangements, caps or reporting obligations. Check current exchange, clearing-house and regulator rules before making a decision that depends on legal ownership or disclosure thresholds.

Do not treat “tax” as one charge. A Northbound trade can involve exchange and settlement fees, broker charges, currency conversion and tax obligations that depend on the jurisdiction and investor. The SSE settlement page, accessed 7 October 2026, lists the following Northbound SSE charges: handling fee of 0.00487% per side, securities management fee of 0.002% per side, Shanghai transfer fee of 0.002% per side, and seller stamp duty of 0.1%. Fee schedules can change, so verify the current exchange schedule and your broker’s charges before trading.
Hong Kong’s Inland Revenue Department says Northbound trades in SSE and SZSE securities are not subject to Hong Kong stamp duty. That answer is limited to Hong Kong stamp duty: it does not establish mainland tax treatment or settle any tax due in your country or territory of residence. For personal tax consequences, consult the applicable tax authority or a qualified adviser.

Which market is the better fit?
There is no general conclusion here that one market offers better returns, lower risk, more liquidity or better valuations. Those depend on the particular security and investor. Compare the actual companies and the practical conditions for trading them, including:
