Screening Chinese Stocks by Positioning, Profit Growth, and Opening Gain

Summary

This note proposes screening Chinese A-shares using three conditions: reported buying or position increase above five percent, year-over-year net profit growth above 20 percent and no more than 100 percent, and a 9:25 a.m. indicated gain below six percent. It interprets the first filter as a sign of capital inflow, the second as evidence of earnings growth, and the third as a limit on the stock's early price move. The article supplies illustrative selection logic, but no backtest, portfolio results, or evidence that the combination has predictive value.

The author notes that buying activity, earnings growth, and early price changes can each be distorted by market sentiment, sector conditions, or accounting differences. Valuation and industry context are not included in the initial screen, and the note suggests adding valuation measures and broader sector or flow data. Its sample code is not a reliable specification of the stated rules: it transforms each input relative to universe averages, making the resulting thresholds difficult to reconcile with the original conditions. The screen also gives no explicit execution, risk, or exit rules.

Key ideas

• The stated screen combines buying activity above five percent, bounded year-over-year profit growth, and a limited 9:25 a.m. indicated gain.
• The note treats buying activity as a possible capital-flow signal and profit growth as a measure of business performance.
• It warns that each input can be affected by market mood, sector dynamics, or accounting practices.
• Valuation and industry conditions are identified as potentially useful additional filters.
• The sample code normalizes values in ways that do not clearly implement the stated thresholds, and no performance evidence is supplied.
