Screening Small, Profitable Chinese Stocks by Turnover and Institutional Holdings

Summary

This document describes a Chinese A-share selection rule that combines turnover between 3% and 12%, market capitalization below 10 billion yuan, positive earnings, and institutional activity above zero. Its refined version focuses on companies whose institutional holdings have increased. A formula and Python example illustrate filtering out ST stocks, checking earnings per share, comparing institutional holdings over time, and limiting market capitalization.

The article argues that moderate size, trading activity, profitability, and institutional buying may help identify candidates, but it provides no backtest or return evidence. It cautions that the rule does not fully account for market conditions or company fundamentals, and that reported institutional activity may be affected by regulatory factors. It suggests evaluating fundamentals and industry conditions alongside the signal. The examples use historical data windows and rely on specific data fields, so implementation depends on data quality and consistent definitions of profitability and holdings growth.

Key ideas

• The screen combines turnover, a market-cap ceiling, positive earnings, and positive institutional activity.
• The refined rule looks for an increase in institutional holdings over time.
• The document provides code examples but no evidence of risk-adjusted performance.
• It advises assessing fundamentals, industry conditions, and the broader market alongside institutional signals.
