Screening Stocks by Large-Order Inflows and a Rising 30-Day Average

Summary

This Chinese equity selection method ranks stocks by a measure of capital strength, keeps those with net large-order inflows during the afternoon, and then filters for a rising 30-day moving average. The rationale is that stronger inflows may indicate buying demand, while the moving average condition selects stocks with an upward recent trend. The document suggests that a longer moving average or added valuation and size criteria could refine the screen.

The evidence is descriptive only: there are no return figures, comparative tests, or details on how the capital-strength and afternoon-flow measures are constructed. The code sample is incomplete and uses generic or unexplained data calls, so it does not establish a reproducible implementation. The author identifies dependence on market sentiment and short-term trend as risks, especially if prices reverse or fluctuate sharply. Data timing, survivorship, execution costs, and the exact definition of a rising average would need to be specified before evaluation.

Key ideas

• The screen prioritizes stocks by a capital-strength measure, then requires afternoon net inflows from large orders.
• A rising 30-day moving average serves as the trend filter.
• The document suggests adding size or valuation criteria and considering a longer trend window.
• The code is incomplete, and the document provides no performance evidence or precise measure definitions.
