A-Share Stock Screen Using Range, Convertible Bond, and Code Filters
Summary
This Chinese-language document presents a screening rule for mainland Chinese A-shares. It selects stocks with a daily high-low range exceeding one percent of the high, a nonempty name for an outstanding convertible bond, and a stock code beginning with 60. It also gives formula and Python examples intended to implement the filters, though the examples appear to apply some additional company, exchange, listing, and industry conditions.
The article characterizes the screen as considering volatility, company fundamentals, and stock type, but the stated conditions provide little direct fundamental analysis beyond the convertible-bond criterion. It warns that the code prefix can exclude other potentially attractive companies and suggests adding valuation, earnings growth, technical, listing-age, or capitalization measures. No backtest, return evidence, or detailed treatment of data consistency is supplied, and the examples should be checked against the intended screening definition before use.
Key ideas
- The proposed screen combines a daily range threshold, an outstanding convertible-bond name, and a stock-code prefix.
- The range condition compares the high-low difference with one percent of the high.
- The article includes formula and Python examples, but the Python version adds filters beyond the core rule.
- The code-prefix constraint may exclude otherwise suitable companies.
- Suggested extensions include valuation, earnings growth, moving averages, listing age, and market capitalization.
- No backtest or performance evidence is provided.
