A-Share Stock Screen Using Buying Activity and Moving Averages

Article SuperMind

Summary

The document presents a Chinese A-share stock screen combining three conditions: today’s increase in holdings exceeds five percent, institutions are described as buying during a price decline, and the 20-day moving average is above the 120-day moving average. It interprets these as signals of buying activity, institutional participation, and a rising short-term trend. A sample selection outline filters a stock universe using corresponding data fields, though the functions that retrieve those fields are not defined.

The text cautions that buying activity and institutional purchases do not guarantee gains, and that a moving-average relationship cannot account for all influences on prices. It suggests adding valuation measures, fundamental and technical analysis, and macroeconomic or policy context. No backtest results, return estimates, or precise operational definition for the institutional-buying condition are provided. The screen is therefore a proposed selection heuristic, and its claims would need independent validation before practical use.

Key ideas

  • The screen requires buying activity above five percent, institutional buying during a decline, and the 20-day average above the 120-day average.
  • The moving-average condition is used as a short-term trend filter.
  • The document warns that none of the three signals guarantees a price increase.
  • It suggests adding valuation, fundamental, technical, and macroeconomic context.
  • No backtest results or detailed definitions for the data inputs are supplied.
