Chinese Stock Screen Using Opening Gain, Recent Limit-Ups, and Volume Ratio

Summary

This proposed Chinese stock screen ranks candidates by volume ratio, requires a limit-up event within the previous 25 days, and filters for an opening gain below 6% at 9:25. The document describes the volume ratio as the measure for ranking capital intensity and a 25-day indicator as the test for a recent limit-up. It also suggests adding industry and profitability filters, though these are recommendations rather than established parts of the core rule.

The article warns of general market volatility and the possibility of missing stocks that fail its criteria. Its sample Python section is incomplete, and no backtest, return figures, or evaluation of the indicators is supplied. Thus, it communicates a screening concept but provides little evidence that the combination has an edge. The opening snapshot and recent limit-up condition may be sensitive to trading rules, market regime, and the reliability of the underlying data.

Key ideas

• The core screen ranks stocks by volume ratio, requires a limit-up event in the prior 25 days, and sets a 9:25 gain ceiling of 6%.
• The article associates volume ratio with capital intensity and uses a recent limit-up as a historical filter.
• Industry and profitability measures are suggested as possible additions.
• The example implementation is incomplete, and the document provides no performance evidence.
