Screening Chinese Stocks by Turnover, Size, Profitability, and Position Changes

Summary

The document outlines an A-share stock screen combining a turnover-rate band, a market-cap ceiling, and a positive-profitability condition with a threshold for the day’s increase in holdings. Its rationale is that the holdings-change measure may help identify buying interest. It also notes that the measure does not reveal why positions increased, which could reflect different investor motives or institutional buying.

The post includes example formula and Python references for applying screening conditions, as well as possible additions such as price movement and fundamental-quality checks. These implementation examples should be read cautiously: the provided formula does not encode every stated screening condition, and the code’s data fields, date handling, and indicator assumptions are not validated in the document. It reports no backtest or investment results, so the screen’s predictive value is not established.

Key ideas

• The proposed screen combines turnover, market capitalization, profitability, and a daily holdings increase threshold.
• The holdings-change measure may indicate buying interest but does not identify its cause.
• The post suggests adding price and fundamental-quality checks as further filters.
• The sample formula and Python code do not demonstrate that the complete screen has been validated.
