Chinese Stock Screening by Intraday Range, Turnover, and Positive PE

Summary

This stock screen selects shares with an amplitude threshold above 1, prior-day actual turnover between 3% and 28%, and a positive price-to-earnings ratio. The stated rationale is to combine a price-range measure and trading activity with a basic profitability-related filter. The document provides example implementations in indicator-formula and Python styles, but these are illustrative and contain differences in how the conditions are expressed, so they should not be treated as a validated specification.

The post gives no backtest, performance data, or evidence that the screen predicts returns. It cautions that PE alone is insufficient for judging value and that sparse criteria can both exclude promising stocks and admit poor candidates. It suggests considering additional measures such as capital flows, company size, PE observations across multiple periods, and macroeconomic conditions. The screen is therefore a candidate-selection rule, not a complete portfolio or trading strategy; entry, exit, sizing, and risk controls are not described.

Key ideas

• The screen combines a price-amplitude threshold with a prior-day turnover band and positive PE.
• The author presents formula and Python examples as implementation references.
• The document offers no backtest or evidence of investment performance.
• PE and the other screening conditions require broader context and additional risk analysis.
