Short-Term Main-Board Screen Using Range, Control, and Daily Gains

Summary

This document presents a short-term screen for Chinese main-board stocks. It selects shares with a daily price range above 1%, a reported daily controlling-shareholder measure whose absolute change exceeds 21%, and a daily gain above 1%. The source also describes ranking candidates by a funds-flow measure and provides reference implementations for a stock platform and Python-style data access. These are specifications and examples, not evidence that the screen earns excess returns.

The stated rationale is to combine price movement, the shareholder-control measure, and a positive daily move to identify stocks for short-term trading. The document warns that the selection relies on a narrow set of technical and short-horizon factors and omits fundamentals, making results potentially unstable. It proposes adding fundamental, technical, and liquidity measures and applying risk controls, but does not define or test those additions. Definitions and data quality for the control and flow measures also matter when reproducing the screen.

Key ideas

• The screen requires daily range above 1%, absolute change in a controlling-shareholder measure above 21%, and a daily gain above 1%.
• The eligible universe is Chinese main-board stocks.
• A sample implementation ranks qualifying stocks by a funds-flow measure.
• The document reports no tested returns and warns that the narrow, short-term inputs may produce unstable results.
