Filtering Chinese Stocks by Turnover, Recent Limit-Ups, and Capital Flows
Summary
This document describes a Chinese A-share screening rule that selects stocks with turnover between 3% and 12% and at least one limit-up event in the prior 25 days. It then ranks candidates by capital-flow strength, specifically referring to net buying through the Shanghai-Hong Kong Stock Connect. The article presents the filter as a way to find actively traded stocks attracting investor attention.
It cautions that capital-flow measures may reflect speculative activity and that the screen omits company performance and valuation. Suggested refinements include adding fundamental, valuation, and technical measures and considering broader market direction and sustained inflows or outflows. The document provides an indicator expression and a Python example, but no backtest, performance evidence, or validation of the proposed refinements. Its implementation details also do not fully establish that the code reproduces every stated screening condition.
Key ideas
- The screen requires turnover between 3% and 12%.\nCandidates must have had a limit-up event within the preceding 25 days.\nThe stated ranking uses capital-flow strength, with the formula specifying Stock Connect net buying.\nCapital flows may capture speculation, and the screen omits fundamentals and valuation.\nThe document proposes adding fundamental, valuation, and technical criteria, but reports no test results.
