A-Share Screen Using Moving Averages, Share Concentration, and Profitability

Summary

This article proposes screening Chinese-listed stocks by combining moving-average conditions, a share-concentration threshold, a market-cap ceiling, and a requirement that the company not be loss-making. It presents moving-average alignment as a way to identify stocks with relatively stable price behavior and potential support or resistance, while the concentration and size filters are intended to focus on smaller companies. It also suggests adding measures of profitability, debt capacity, trading volume, or other technical indicators.

The rationale is descriptive rather than supported by market data: the article gives no backtest, selected-stock examples, or evidence that the conditions improve returns. Its explanation of the concentration threshold is unclear, and the code appears incomplete and inconsistent: it applies chained moving-average comparisons, uses a volatility field for the concentration condition, and ends with a truncated market-cap filter. These ambiguities make the proposed screen difficult to reproduce as written, and the article acknowledges that its criteria do not guarantee successful investments.

Key ideas

• The proposed screen combines moving-average conditions with company size and profitability filters.
• The article suggests adding financial strength and trading indicators to refine selection.
• The meaning of the share-concentration threshold is not clearly defined.
• The example code is truncated and does not faithfully implement every stated criterion.
• No backtest or other performance evidence is included.
