A Chinese Stock Screen Using Amplitude, Float Size, and Price

Summary

The document describes a Chinese equity screening rule based on prior-session price amplitude, tradable share count, and a target share price. It presents both indicator-style and Python examples, then suggests ranking qualifying stocks by turnover when the candidate set exceeds a chosen fraction of the universe. The intended rationale is to find more volatile smaller-capitalization shares at a specified price level, potentially suited to short- or medium-term trading.

The article acknowledges that the screen omits company fundamentals and financial condition, and that market-wide changes or company-specific events can undermine its selections. It recommends adding fundamental, valuation, market, volume, and capital-flow measures. The examples are illustrative rather than evidence of performance: no backtest, transaction-cost treatment, or evaluation results are supplied. The exact-price condition is restrictive and the text inconsistently describes the target price, so the rule should be treated as a rough screening idea rather than a validated strategy.

Key ideas

• The screen combines recent price amplitude, tradable share count, and a target share price.
• The examples show how to express the filters in indicator-style and Python workflows.
• Turnover is proposed as a ranking criterion for the stocks that pass the filters.
• The article warns that the rule omits fundamentals and can be vulnerable to market or company events.
• No backtest or performance evidence is provided, and the stated target price is inconsistent.
