A Chinese Stock Screen Combining Price Movement and Convertible Bond Data

Summary

The document presents a Chinese equity screening rule that combines a price movement threshold, the presence of an outstanding convertible bond name, and a limit on the opening price change relative to the prior close. It describes these as signals related to volatility, company financing, and market behavior. The post also includes indicator-formula and Python examples, suggesting how to screen listed shares using daily price and financial data. Its stated discussion recommends considering additional fundamental or technical measures when refining the selection process.

The screen is a rule proposal rather than a validated trading system. The post warns that relying heavily on opening gains and technical or market conditions can produce misleading selections and overlook company fundamentals. The formula and Python example do not appear to implement precisely the same stated conditions, and the code’s data conventions and selection details are not fully reconciled. No backtest methodology, benchmark comparison, transaction cost estimate, or performance evidence is supplied, so its predictive value cannot be inferred from the document.

Key ideas

• The proposed screen combines a price movement condition, convertible bond information, and an opening gap range.
• The post interprets these inputs as reflecting volatility, financing circumstances, and market behavior.
• It supplies formula and Python examples, though they do not clearly match all stated conditions.
• The author notes that market-based filters can overlook company fundamentals.
• No backtest evidence or trading performance results are provided.
