A-Share Screen Using Institutional Buying and Pre-Open Gains

Summary

This document outlines an A-share stock screen based on three conditions: buying activity above 5%, evidence of institutional buying, and a pre-open gain below 6%. It presents the combination as a way to find stocks attracting capital without already showing a large indicated opening move. The article suggests that profitability, valuation, dividends, and technical indicators could be added as further filters.

The post includes illustrative filtering logic, but no backtest or performance evidence. Its explanation notes that institutional buying signals may not predict gains, elevated buying activity may reflect sentiment rather than durable inflows, and pre-open prices do not determine subsequent trading. The example’s field definitions and comparison for the pre-open condition are unclear, so the screen would require careful data validation before evaluation.

Key ideas

• The screen combines buying activity above 5%, an institutional buying signal, and a pre-open gain below 6%.
• The author treats capital interest as a selection clue rather than a guarantee of future gains.
• Possible refinements include adding profitability, valuation, dividend, and technical filters.
• The post gives no measured results, and the sample data fields and pre-open calculation need clarification.
