Chinese Stock Screening with Buying Pressure and a Rising 30-Day Average

Summary

This stock screen combines a rising 30-day moving average with two measures intended to represent buying activity: a daily increase in holdings above 5% and the ratio of external to internal trading volume above 1.3. The document interprets a higher external-to-internal ratio as stronger active buying and treats the moving average as a longer-term trend filter. It includes a simple conceptual selection procedure that checks all three conditions for each stock.

The author cautions that the rules focus on recent price and trading behavior and may not predict longer-term performance. Apparent buying pressure could also accompany unfavorable news or other risks. Suggested improvements include adding technical and fundamental indicators and a stop-loss mechanism. The document provides no historical test, performance results, or detailed definitions of the holdings and volume measures, so it does not establish that the screen has predictive value.

Key ideas

• The screen requires a rising 30-day moving average and a daily increase-in-holdings measure above 5%.
• It also requires external trading volume to exceed internal volume by more than the stated ratio threshold.
• The document warns that recent buying activity can be misleading and may coincide with adverse information.
• It suggests adding other indicators and risk controls, but reports no backtest results.
