Screen the Beijing Stock Exchange (北京证券交易所 / 北交所) — China's third national exchange, launched 2021 for "specialized & sophisticated" (专精特新) SME and innovation-stage companies, tickers starting 8 or 4. Pull the headline 北证50 (BSE 50) constituents or the whole ~270-name board with live price, P/E, P/B, turnover and market cap (RMB), plus a xxxxxx.BJ symbol. Note: this is the Beijing exchange — not Bombay (BSE India); for SENSEX use the separate India screener.

Beijing Stock Exchange (北交所) data for offshore China-watchers tracking China's under-covered SME / 专精特新 board.

What it does

• Pulls live Beijing Stock Exchange quotes from Eastmoney's push2 public quote API (北交所, 8xxxxx / 4xxxxx tickers).
• Scope filter: BSE-all (whole ~270-name board) or BSE50 (北证50 index leaders).
• Filters by minimum market cap (RMB billion) and a case-insensitive sector keyword.
• Returns ticker, name, board, index label, is_bse50 flag, yahoo_symbol (xxxxxx.BJ), price (CNY), % change, P/E, P/B, turnover, volume, market cap (CNY + RMB billion), float caps, and a best-effort sector tag.

Notes: 北证50 (BSE 50) membership is provided as a best-effort headline-name flag, not a live-rebalanced constituency. The sector field is a best-effort classifier, not official GICS. Dividend yield and ROE are not emitted. This screens the Beijing exchange (北交所), not Bombay (BSE India).

4. Building an all-China-boards universe by adding Beijing names to SSE / SZSE / STAR / ChiNext.
5. Sector screen ("Optics", "Battery Materials", "Biotech") across the Beijing SME board.

FAQ

What tickers trade on the Beijing exchange? They start with 8 (e.g. 832000) or 4 (e.g. 430047).
