A-Share Screening with Moving-Average Trend and Buying Activity

Summary

This stock screen combines three conditions: the share price’s 20-day moving average must be above its 120-day moving average, the stock must have been listed for more than 20 days, and today’s buying-volume share must exceed 5%. The document presents this as a way to find stocks with an established upward trend and current buying interest. It also suggests adding valuation or market-cap filters and other technical indicators to broaden the assessment.

The article offers a qualitative rationale and a code sketch, but no backtest, performance results, or evidence that the conditions predict future returns. Its explanation treats a moving-average relationship as a possible sign of continued gains, while acknowledging that weak market conditions or falling prices can still lead to losses. The sample code also appears to stop iterating once it finds one qualifying buying-volume value, yet returns the full moving-average-filtered list; it does not clearly apply the buying-volume condition to each stock. The screening logic therefore needs careful implementation and independent testing.

Key ideas

• The screen requires the 20-day moving average to exceed the 120-day moving average.
• It excludes stocks listed for 20 days or less and requires today’s buying-volume share to exceed 5%.
• The document proposes adding fundamental and technical filters for a broader screen.
• It provides no performance testing, and the sample code may not correctly filter each stock by buying-volume share.
