Stock Screening with Price Range, Trading Volume, Gaps, and Convertible Bonds

Summary

This Chinese stock screening proposal combines a daily price-range threshold, trading volume above 10,000 lots, a higher opening price, and a nonempty label for outstanding convertible bonds. It argues that larger price movement and greater volume may help identify active stocks, while a higher open and convertible-bond exposure could point to potential upward catalysts. The document also provides example indicator and Python implementations, though the Python filters do not clearly implement every stated condition in the same way.

No backtest results or performance evidence are presented. The author warns that the screen emphasizes technical and trading data, leaves out company fundamentals and other relevant factors, and treats outstanding convertible bonds as an uncertain signal that can coincide with substantial volatility. Suggested improvements include adding fundamental, industry, and price-related measures and assessing risk using multiple factors. The proposed screen is therefore a selection heuristic, not evidence that the chosen stocks will rise.

Key ideas

• The screen combines price amplitude, current trading volume, a higher open, and an outstanding convertible-bond label.
• The stated volume threshold is more than 10,000 lots.
• The document suggests that price activity and convertible-bond exposure may indicate possible trading interest or catalysts.
• It provides sample implementations but no backtest evidence of profitability.
• The author recommends adding fundamental and industry analysis and accounting for convertible-bond uncertainty.
