A-Share Screen for High Amplitude and Smaller Circulating Share Capital

Summary

The article describes a short-term A-share screening rule combining three conditions: prior-session price amplitude above 1%, circulating shares no greater than 5.5 billion, and a stock code beginning with 60. Its sample implementation intersects these filters and ranks qualifying stocks by turnover rate, taking a fraction of the candidates. The article also gives indicator and Python examples for calculating the filters.

It presents the screen as a way to find volatile, relatively smaller stocks, but provides no backtest, performance evidence, or detailed definition of how the ranking fraction should be applied. It cautions that market conditions can weaken the rule, code-prefix selection is subjective, and short-term technical trading carries risk. The suggested improvements are to consider company fundamentals and sector context, diversify holdings, and combine shorter- and longer-term approaches. These suggestions are general; no specific validation method or portfolio sizing rules are supplied.

Key ideas

• The screen requires prior-session amplitude above 1%, circulating shares at or below 5.5 billion, and a code starting with 60.
• The example ranks stocks passing all three filters by turnover rate.
• The article frames the screen as a short-term approach but supplies no performance test.
• It identifies changing market conditions and subjective code-based selection as limitations.
• It recommends adding fundamental and sector analysis and diversifying exposure.
