Chinese Stock Screen Using Turnover, Reversal, and Year

Summary

This document describes a Chinese equity screen combining a turnover rate between 3% and 12%, a reversal or engulfing-style condition, and a 2021 date filter. It offers a market-screen expression and a Python sketch that derives a reversal measure from the distance between the prior close and the day’s high or low, then filters stocks. The screening idea is therefore a rule-based technical selection process rather than a portfolio or trading plan.

The article gives no performance results or validation. Its date rationale is inconsistent: the discussion mentions a 2019 restriction, while the stated screen and code refer to 2021, and the example daily data uses another date. The code also contains apparent missing or mismatched data references. The text acknowledges that it omits company fundamentals and that narrow conditions can produce an unrepresentative list; it suggests adding other indicators or valuation measures and widening the criteria. Any use would require resolving these inconsistencies and independently testing the signal.

Key ideas

• The screen combines 3%–12% turnover with a reversal condition and a 2021 date filter.
• The example reversal measure uses the prior close relative to the current day’s range.
• The document provides no evidence that the screen generates positive returns.
• The date references and code contain inconsistencies that require clarification.
• The article warns that missing fundamentals and restrictive filters may weaken the selection.
