Screening Chinese Stocks by ROE, Daily Range, and Afternoon Flows

Summary

The document describes a Chinese equity screen that combines a daily high–low range threshold, return on equity above 15% for each of five years, and afternoon large-order net inflows. It frames the range condition as a way to select more active shares, the ROE condition as a profitability filter, and the flow condition as a sign of buying interest. A suggested refinement ranks stocks by afternoon inflows and adds revenue, profit, and cash-flow quality checks.

The post includes example indicator logic and Python-style code, but provides no backtest results or evidence that the screen predicts returns. It warns that the approach may follow market mood, omit valuation, and react to noisy individual trades. It suggests adding broader market context, valuation measures, and smoothing or ranking flow data. The implementation details also leave ambiguities, including how the afternoon period is defined and how the stated ROE history maps to the sample data.

Key ideas

• The proposed screen combines daily price range, five years of high ROE, and afternoon net buying by large orders.
• The author suggests ranking stocks by afternoon inflows and adding growth and cash-flow checks.
• The post identifies market sentiment, missing valuation analysis, and noisy flow observations as risks.
• No performance evidence is supplied, and several screening details are not fully specified.
