What are China A‑shares?
– Definition: China A‑shares are equity shares of companies incorporated in mainland China that are listed and traded on the two domestic exchanges—the Shanghai Stock Exchange (SSE) and the Shenzhen Stock Exchange (SZSE). These shares are quoted and settled in the Chinese currency, the renminbi (RMB), and are commonly referred to as “domestic shares.”
Key distinctions to know
– Currency: A‑shares trade in RMB. By contrast, China B‑shares are quoted in foreign currencies (for example, U.S. dollars) and historically offered an easier route for non‑Chinese investors.
– Market access: For many years A‑shares were reserved for mainland Chinese investors. From the early 2000s, China introduced controlled channels that allow some foreign institutions to buy A‑shares; the Qualified Foreign Institutional Investor (QFII) program, launched around 2002–2003, is one such route.
– Valuation gaps: The same company can have A‑share and B‑share listings. Because of differences in investor base and access, the A‑share quote for a company often trades at a premium relative to its B‑share quote.
Short historical context
– A‑shares began trading on the domestic exchanges after the exchanges were created around 1990. Reforms in the early 2000s (including the QFII regime) opened limited access for qualified foreign institutions.
– A commonly used benchmark for large, liquid A‑shares on the Shanghai exchange is the SSE 180 Index, which is composed of 180 stocks selected to represent a mix of sectors, market caps, and liquidity characteristics.
– The Shanghai market has experienced large swings since its inception; for example, a 52‑week performance metric showed a notable decline in the 2015–2016 period. More recently, major global index providers have gradually started to include China A‑shares in international benchmarks, increasing foreign interest.
Practical checklist before you consider exposure to A‑shares
– Confirm the trading venue: SSE or SZSE—and whether the company has both A‑ and B‑share listings.
– Confirm the currency: A‑shares are priced in RMB; account for FX conversion and settlement mechanics.
– Confirm investor access: Are you an eligible foreign institution (QFII) or using an approved channel? Retail access rules differ from institutions.
– Check repatriation rules: be aware of any limits on moving funds out of China (e.g., a 20% monthly cap has applied to repatriation in some programs).
– Compare A vs B pricing and liquidity: the same issuer can show a material valuation differential between domestic (A) and foreign‑currency (B) listings.
– Review index inclusion and liquidity: being included in major indices (like the SSE 180 or partial MSCI inclusion) affects flows and trading volume.
Step‑by‑step (institutional investor) — simplified
1. Confirm eligibility for QFII or other approved program that permits A‑share trading.
2. Apply for required licences/quotas and open onshore RMB custody accounts as required by the program.
3. Select specific A‑share securities or index exposure, taking liquidity and sector balance into account.
4. Execute trades on SSE or SZSE in RMB and monitor FX exposure.
5. Plan repatriation of proceeds in compliance with monthly or programmatic limits.
6. Reconcile holdings and reporting as required by Chinese regulators and your home jurisdiction.
Worked numeric example — comparing an A‑share price to a B‑share price
Assume:
– A‑share price (Shanghai listing): 65.00 RMB
– B‑share price (same company, quoted in USD): 8.00 USD
– Spot FX rate: 1 USD = 6.50 RMB
Step 1 — convert the B‑share price to RMB:
8.00 USD × 6.50 RMB/USD = 52.00 RMB
Step 2 — compute the A vs B premium:
Premium = (A‑share price − B‑converted price) / B‑converted price
Premium = (65.00 − 52.00) / 52.00 = 13.00 / 52.00 = 0.25 → 25%
Interpretation: in this example, the A‑share trades at a 25% premium to the B‑share expressed in the same currency. That premium can arise from differences in investor composition, demand, liquidity, and access restrictions.
Quick numeric example — repatriation cap
If a foreign investor wishes to repatriate the equivalent of 1,000,000 USD from onshore RMB holdings and a program limits repatriation to 20% per month:
– Monthly allowable repatriation = 20% × 1,000,000 USD = 200,000 USD
– Remaining balance that must wait until subsequent months = 800,000 USD
Why index inclusion matters (brief)
Major index providers’ partial inclusion of A‑shares increases foreign exposure and trading liquidity for included stocks. For example, a phased approach to adding large‑cap A‑shares to international emerging‑market benchmarks can lead to incremental inflows as passive funds track those indices.
