Chinese A-Share Screening with Limit-Ups and Capital Strength

Summary

This Chinese A-share screening idea ranks stocks by capital strength and selects those described as having main-fund control on the previous day and more than two limit-up sessions in the past ten days. The post interprets these conditions as signs of capital inflow, active trading interest, and strong recent expectations. It also suggests adding moderate market capitalization and price-to-earnings filters, then mentions volume ratio and turnover ranking as possible proxies for the capital-related criteria.

The article provides a proposed rule set and general rationale, but no backtest, performance data, or defined calculation for “main-fund control” or capital strength. It cautions that the filters cannot ensure gains and may omit stocks that rise for other reasons. The suggested valuation and size filters are qualitative, and the accompanying implementation discussion is incomplete, so the screen would need precise data definitions and historical testing before use.

Key ideas

• The screen combines capital-strength ranking with prior-day main-fund control and repeated recent limit-up events.
• The author interprets the conditions as indicators of inflows, attention, and upward expectations.
• Moderate market capitalization and valuation are suggested as additional filters.
• The post offers no performance evidence, and its criteria require clearer operational definitions and testing.
