A Chinese Stock Screen Combining Price Range, Rising Lows, and Holder Concentration

Summary

This Chinese-language post describes an equity screening rule that combines a price amplitude threshold, rising lows, and a measure of shareholder concentration. It presents the rule in a screening formula and gives a Python example that checks recent low prices and holder distribution. The post also recommends adding fundamental measures, such as valuation and earnings or revenue growth, to refine the selection.

The author characterizes the screen as potentially biased toward popular stocks and warns that selected names may be volatile or fail to deliver expected returns during sharp market moves. The code is presented as a reference and would need adaptation to the data source and platform. The post supplies no backtest, portfolio construction rules, transaction cost assumptions, or performance evidence. Its definitions are also not fully consistent: the formula and Python example use different expressions for amplitude and concentration, so the screening conditions need clarification before implementation.

Key ideas

• The screen combines price amplitude, a rising-lows pattern, and a shareholder concentration condition.
• A sample implementation checks whether recent lows rise in sequence.
• The post suggests adding valuation and business growth measures as further filters.
• The author warns that the screen may select volatile, popular stocks and offers no performance evidence.
• The formula and code differ in how some conditions are expressed, so their meaning should be checked before use.
