Chinese Stock Screen Using Limit-Up Activity and Capital Strength

Summary

This Chinese stock-screening example ranks shares by capital strength and initially selects stocks with more than two limit-up sessions in the previous ten days and a gain below six percent at 9:25. The accompanying explanation treats stronger capital inflow and repeated limit-ups as signs of attention and upward momentum, while the opening-time price filter is intended to avoid shares already showing an especially large early rise.

The article then presents a revised set of criteria: capital strength ranking, the same ten-day limit-up threshold, a gain above ten percent over twenty days, market capitalization above 10 billion yuan, and a price-to-earnings ratio below 20. It offers a rationale for the filters but no backtest, comparison, or risk-adjusted results. It acknowledges that momentum and attention do not ensure future gains and suggests adding valuation, size, or alternate lookback conditions. The sample code is incomplete, so the selection rules are more informative than the implementation.

Key ideas

• The initial screen combines capital strength, recent limit-up frequency, and a pre-open gain ceiling.
• The revised screen adds a twenty-day return filter, a minimum market capitalization, and a maximum price-to-earnings ratio.
• The article interprets capital inflow and repeated limit-ups as indicators of attention and momentum.
• The filters are not supported by backtest results, and the example code is incomplete.
• The author cautions that these conditions cannot guarantee future gains.
