A-Share Screening with Capital Inflow, Weekly MACD, and Moving Averages

Summary

This stock screen combines a capital-inflow measure with two trend filters. It selects A-shares when the day’s increase in holdings exceeds 5%, weekly MACD is above zero, and the 20-day moving average is above the 120-day moving average. The article interprets the inflow condition as possible buying interest and the MACD and moving-average conditions as signs of positive trend. Together, the rules aim to find stocks with both recent demand and an established upward bias.

The document provides a conceptual explanation and pseudocode-style selection logic, but no backtest, benchmark, return series, or evidence that the signals predict gains. It cautions that trend and flow measures can fail in extreme markets and that inflows may not lift a stock whose price is already high. It suggests adding valuation measures or combining indicators, such as MACD with Bollinger Bands, but does not specify or test those additions. The meaning and calculation of the holdings-increase ratio are not detailed, so implementation requires a consistent data definition.

Key ideas

• The screen requires daily holdings growth above 5%, weekly MACD above zero, and the 20-day average above the 120-day average.
• The conditions combine a capital-flow proxy with trend filters to identify candidate A-shares.
• The article frames the signals as possible evidence of buying interest and an upward trend, not as guaranteed entry signals.
• It warns that indicators may fail in extreme markets and that inflows may not support further price gains.
• No performance data or tested optimization is provided, and the holdings measure is not precisely defined.
