Screening Chinese Stocks by Turnover and Ten-Day Price Change

Summary

This document proposes screening Chinese stocks by turnover rate, recent price performance, and market-board exclusions. The stated rules select stocks with turnover between 3% and 12%, a ten-day gain above zero but below 35%, and exclude the ChiNext and STAR Market boards. The author frames turnover as a measure of activity and the price-change band as a short-term trend filter, then suggests supplementing these conditions with profitability, valuation, and analyst data.

The post warns that simple activity and price measures cannot capture long-term company prospects, while short-term volatility can lead to misleading signals. Its sample Python implementation does not cleanly match the stated screen: it uses stock-code prefixes for exclusions, computes average turnover over downloaded daily data, and calculates a period return, so its exact measurement windows and thresholds may differ from the narrative conditions. No backtest methodology, performance results, or evidence for the proposed risk characterization is supplied. The rules are therefore a screening proposal, not demonstrated evidence of low risk or future returns.

Key ideas

• The screen uses a turnover band of 3% to 12% and a positive ten-day gain below 35%.
• It excludes stocks on the ChiNext and STAR Market boards.
• The author recommends adding earnings, valuation, and analyst information for broader evaluation.
• The article notes that short-term activity and price measures can miss long-term business conditions.
• The Python example may not calculate the stated screening conditions exactly, and no performance evidence is provided.
