Filtering Beijing Stock Exchange Listings from A-Share Labels
Summary
This brief exchange explains how to exclude Beijing Stock Exchange listings when labeling Chinese A-share stocks with a default template. It recommends using an A-share filtering module or adding a custom Python filter to the workflow. The suggested selection is based on stock-code prefixes: exclude codes beginning with 83, 43, or 87, or retain codes beginning with 6, 0, or 3.
The note is a practical platform tip rather than a discussion of investment signals or trading performance. It gives no validation results and does not address changes in exchange listings, exceptions to the prefix rules, or whether the same codes apply in every data source. Users should verify the universe produced by their own data and labeling setup.
Key ideas
- An A-share filtering module can restrict the stocks included in labeling.
- A custom filter can exclude Beijing Exchange listings by stock-code prefix.
- The note also suggests retaining codes beginning with 6, 0, or 3.
- The guidance concerns universe selection and provides no performance evidence.
