Check the ticker, exchange and currency before interpreting a China Construction Bank (CCB) quote: its Hong Kong H-shares trade as 939 on the Hong Kong Stock Exchange (HKEX) in Hong Kong dollars, while its mainland A-shares trade as 601939 on the Shanghai Stock Exchange (SSE) in RMB. Then check that exchange’s current trading calendar and session schedule; a broker may accept an order while the exchange is closed.
Identify which China Construction Bank share you are viewing
CCB has two listings. The ticker alone is not enough if a quote page omits the exchange or uses a shortened symbol: verify all three details—share class, ticker and venue—on the quote screen.
| Share class | Ticker | Exchange | Trading currency |
|---|---|---|---|
| H-share | 939 | Hong Kong Stock Exchange (HKEX) Main Board | Hong Kong dollars (HKD) |
| A-share | 601939 | Shanghai Stock Exchange (SSE) | Renminbi (RMB) |
CCB’s investor FAQ and Chinese-language investor FAQ confirm the ticker-to-exchange mapping. Its disclosure dated 30 March 2025 identifies the trading currencies for the two listings; see the CCB disclosure.

Look for a currency code or label beside the price, such as HKD or RMB. Do not infer it from the CCB name, the language or locale of the quote website, or your own account’s base currency. A price in HKD and a price in RMB are not directly comparable as if they were the same unit; they are quotes for different share listings on different exchanges.

Find trading hours for the correct exchange
Use the current official calendar and session schedule for the venue that matches the ticker: HKEX for 939 and SSE for 601939. Check the date, the exchange’s local time zone, public holidays and any special market arrangements. The official CCB materials cited here do not provide a complete current ordinary-hours schedule for both exchanges, so consult the relevant exchange rather than relying on a general schedule or an old quote page.
Also distinguish a quote from an order. A broker or bank interface may let you submit an instruction outside market hours, but that does not mean the exchange is open or that the order has executed. CCB (Asia) says orders submitted outside trading hours or on a non-trading day are treated as instructions for the next relevant trading day. For Northbound Trading, it says orders can be placed only during Shanghai market hours. These are that provider’s order-handling rules, not a replacement for the exchange calendar. See the CCB (Asia) securities FAQ.

Know what a quote service actually provides
CCB (Asia) says its securities customers can view quotes before placing an order. Its streaming-quote feature is chargeable and requires a securities trading account, online banking, and an application through a branch. This information describes that service; it does not establish that every website or app shows real-time quotes, or that access is free. Check the provider’s own quote label and service terms to determine whether its data is streaming or delayed.
