ADR vs H-Share vs A-Share: The Differences That Matter
Chinese companies often trade in several places at once. Here's how US ADRs, Hong Kong H-shares and mainland A-shares differ in access, currency, liquidity and risk.

A single Chinese company can trade in several places at once — and the version you buy changes how you access it, what currency you hold, how liquid it is, and which risks you take on. Here's how the three main share classes compare.
The three share classes at a glance
| US ADR | H-share (Hong Kong) | A-share (mainland) | |
|---|---|---|---|
| Listed on | NYSE / NASDAQ | Hong Kong (HKEX) | Shanghai / Shenzhen |
| Currency | USD | HKD | RMB (renminbi) |
| Who can buy easily | Anyone with a US-capable broker | Broker with HKEX access | Via Stock Connect / QFI / funds |
| Main risk flavour | US delisting / audit dispute | Currency, local liquidity | Access limits, capital controls |
| WealthyTec region tag | US | Hong Kong | Not directly covered |
US ADRs
The most convenient for international investors: depositary receipts that trade in USD on US exchanges. Easiest access, but they carry the US–China delisting risk and often a VIE structure.
H-shares and Hong Kong listings
Shares of Chinese companies listed in Hong Kong, trading in HKD. Hong Kong is the widest market open to foreigners and is outside the reach of the US delisting mechanism — which is why many companies maintain both a US and a Hong Kong listing. The same economic interest in the company, accessed through a different, arguably more durable venue.
A-shares
Mainland-listed shares in Shanghai and Shenzhen, priced in renminbi. They're the deepest pool of Chinese equities but access is deliberately gated for foreigners through Stock Connect, the QFI scheme, or funds. Pricing can diverge from the same company's H-shares because the two investor bases are partly separated.
Dual-listed companies and the A-H premium
When a company trades as both an A-share and an H-share, the two prices often differ — the "A-H premium." It reflects the segmented markets, different liquidity and currency, and capital-flow restrictions, not a free-money arbitrage (you generally can't convert one into the other). For a foreign investor choosing between an ADR and a Hong Kong line of the same company, the decision is usually about access, currency, and delisting exposure rather than valuation.
