Screening Chinese Stocks by Volatility, Profitability, Size, and Control

Summary

This post describes a Chinese A-share screen combining daily price range, market capitalization, positive net profit, and a signal labeled as prior-day major-player control. Its stated thresholds are a daily high-low range of at least 1%, positive market value up to 10 billion yuan, and positive net profit. The post also supplies example formula logic and a Python-style selection outline.

The rationale is to find relatively volatile, smaller profitable companies with substantial investor participation. The author cautions that apparent large-player control may reflect short-term speculation, and that focusing on price movement or technical signals can neglect company fundamentals and broader market conditions. Suggested refinements include combining financial, technical, and fundamental measures, adapting screening frequency, and checking volume and sentiment. No backtest, performance evidence, or precise definition of the control signal is provided, so the screen should be treated as an idea rather than a validated strategy.

Key ideas

• The screen selects profitable A-share companies with market capitalization up to 10 billion yuan and a daily price range of at least 1%.\nIt adds a prior-day signal described as major-player control, though the post does not define that signal in detail.\nThe author recommends combining technical filters with fundamental and financial analysis.\nLarge-player activity can be speculative and does not establish a stock’s value or future returns.
