Chinese Stock Screen Using Daily Amplitude, Listing Age, and Turnover

Summary

This stock selection screen combines a recent price movement filter with listing history and trading activity. It seeks shares whose daily amplitude exceeds the stated threshold, that have been listed for more than a year, and whose previous day’s trading value exceeds the stated minimum. The article presents these conditions as a way to find active stocks while excluding very recently listed companies. It also includes reference formulas and sample Python selection logic.

The article warns that qualifying stocks can still face company specific events or financial problems, and that strong activity on one day may not persist. It notes that screening for rapid price movement can leave stocks vulnerable to pullbacks. The sample implementation does not fully align with the written criteria: it uses a close to close change as its movement measure and appears to compare volume against a trading value threshold. These differences mean the supplied example should not be assumed to implement the described screen exactly. No backtest or performance evidence is provided.

Key ideas

• The screen combines a daily amplitude threshold, a minimum listing age, and a previous day trading value threshold.
• The article presents amplitude and trading activity as indicators of market activity.
• It identifies company events, financial problems, and price reversals as risks.
• The article suggests adding technical, fundamental, and risk measures to refine selection.
• The sample code and written screening criteria do not match fully, and no performance test is reported.
