How to convert or hold Chinese stocks via Hong Kong (HKEX) if a US listing ends
What an ADR-to-Hong Kong conversion actually involves — the depositary bank, the timeline, the fees and taxes — which US-listed Chinese names already have a Hong Kong line to fall back on, and what having no Hong Kong secondary listing means in practice. Written the week the first 2026 delisting (TIRX) took effect.

On 6 July 2026, Tian Ruixiang Holdings (TIRX) became the first fully completed US delisting of this cycle. The moment a removal actually goes effective, the question stops being abstract: "my US-listed Chinese stock could go away — what happens to my shares, and how does the Hong Kong route actually work?" This guide walks through the Hong Kong (HKEX) fallback in practical terms. It is general information, not investment advice, and not a recommendation to convert, buy, or sell anything.
Why Hong Kong is the fallback venue
Hong Kong has deliberately positioned itself as the landing pad for US-listed Chinese companies. Over recent years the largest names have added a Hong Kong line precisely so that a forced US removal would be an orderly migration rather than a cliff. By value, a large majority of US-listed Chinese firms already carry a Hong Kong secondary or dual-primary listing — which is why the single most useful thing you can check about any holding is whether that Hong Kong line already exists.
Three listing structures — and why the difference matters
"Has a Hong Kong listing" is not one thing. The structure determines how smooth a conversion would be.
- Dual primary listing. The company is independently listed in both the US and Hong Kong, each standing on its own. A US removal leaves the Hong Kong listing essentially unaffected — the most insulated position.
- Secondary listing. The Hong Kong line is secondary to the US primary. Hong Kong's rules are designed so that if the US listing is removed, the secondary listing can automatically convert to primary, with the exchange able to grant a grace period on the listing rules where needed.
- No Hong Kong line at all. The messiest path — an OTC interim in the US, a scramble to establish a Hong Kong listing, or a broker-dependent conversion. This is the exposure to watch.
Which names already have a Hong Kong line — and which don't
These are factual, sourced listing-status data points, not calls on any company. Listing structures change, so confirm the current status on the company's own filings or the screener before relying on it.
| Company | US listing | Hong Kong status | Fallback smoothness |
|---|---|---|---|
| Alibaba (BABA) | NYSE | Hong Kong listing (converted to dual-primary) | Most insulated |
| JD.com (JD) | Nasdaq | Hong Kong dual-primary listing | Most insulated |
| Baidu (BIDU) | Nasdaq | Hong Kong listing | Insulated / smooth |
| PDD Holdings (PDD) | Nasdaq | No Hong Kong listing | Messiest path |
| Full Truck Alliance (YMM) | NYSE | No Hong Kong listing | Messiest path |
The pattern is what matters more than any single row: the mega-cap internet names largely have their Hong Kong fallback in place, while the two most-cited exceptions — PDD (Pinduoduo / Temu) and Full Truck Alliance — carry the most venue risk precisely because they do not yet have a Hong Kong line.

What an ADR-to-Hong-Kong conversion actually involves
If you hold the US-listed ADR of a company that also trades in Hong Kong, many brokers let you convert the ADR into the underlying Hong Kong ordinary shares. Mechanically, the steps look like this:
- The depositary bank is the hinge. An ADR is a receipt issued by a depositary bank against Hong Kong shares it holds. A conversion is that bank cancelling your ADRs and releasing the corresponding Hong Kong shares to your broker.
- You need Hong Kong market access. Your brokerage account has to be able to hold and trade Hong Kong-listed shares. Not every broker offers this; it is the first thing to confirm.
- Timeline: on the order of a couple of business days. A conversion is a settlement process, not an instant swap — commonly around two business days, though it varies by broker and depositary.
- Fees and taxes apply. Depositaries typically charge a per-share ADR cancellation fee; Hong Kong trades carry stamp duty and other market charges; your broker may add its own conversion fee. The ratio of ADR-to-ordinary shares also matters — one ADR often represents several (or a fraction of) Hong Kong shares.
What "no Hong Kong secondary" means in practice
For a name with no Hong Kong line, a completed US delisting removes the primary trading venue without an automatic fallback. In that scenario the common outcomes are an OTC market in the US (typically thinner liquidity and wider spreads), a wait while the company establishes a Hong Kong listing, or broker-dependent handling. A delisting removes where the shares trade — it does not cancel the underlying ownership — but the friction is real, which is exactly why the dual-listing check is the practical priority.
How this connects to the delisting risk itself
This guide is the "what do I do about it" companion to the underlying policy question. For how the delisting risk arises — the HFCAA, the PCAOB audit dispute, the 2026 escalation, and the first completed removals — see Chinese ADR delisting risk.

Frequently asked questions
Can I convert my US ADR into Hong Kong shares?
Often yes, if the company has a Hong Kong listing and your broker supports Hong Kong market access. The depositary bank cancels the ADRs and releases the underlying Hong Kong shares; it typically takes on the order of a couple of business days and involves fees. Confirm the exact process with your broker — this is general information, not advice.
Which Chinese companies can I hold via Hong Kong?
The large US-listed internet names — Alibaba, JD.com and Baidu among them — already carry a Hong Kong listing, so they can be held via Hong Kong. The most-cited names without a Hong Kong line are PDD Holdings and Full Truck Alliance. Check the current status of any holding in the screener.
What if my stock has no Hong Kong listing and gets delisted?
A US delisting doesn't erase your ownership, but without a Hong Kong fallback the shares may trade OTC with reduced liquidity, or you may wait for the company to establish a Hong Kong listing. This venue risk is why the presence of a Hong Kong line is the single most useful thing to check.
Is a secondary listing as safe as a primary one?
A dual-primary Hong Kong listing stands fully on its own. A secondary listing is designed to convert to primary automatically if the US listing is removed, with a possible grace period — smooth, but a step removed from a standalone primary. The share-class mechanics are covered in ADR vs H-share vs A-share.
