Screening Stocks by Turnover, Reversal Patterns, and Recent Limit Ups

Summary

The post outlines a Chinese stock selection screen combining a daily turnover rate between 3% and 12%, a reversal or engulfing style price pattern, and at least one limit up during the preceding 25 trading days. It describes the recent limit up as a way to identify stocks with strong short term activity, while the reversal condition and turnover band further narrow the candidates. Formula references and a sample data workflow illustrate how the filters might be assembled, but the excerpt does not define the reversal measure consistently across its examples.

The author warns that the screen omits company fundamentals, may yield too few and unrepresentative stocks, and that a previous limit up does not predict future gains. Suggested extensions include adding technical and valuation measures or loosening the filters. No performance results or out of sample tests are given. The code is an example rather than a validated strategy, and its data joins and stock universe filters would need scrutiny before use.

Key ideas

• The screen combines a 3%–12% turnover range, a reversal pattern, and a recent limit up event.
• The post presents indicator formula references and a sample workflow for combining market data.
• The author notes that strict filters can shrink the candidate set and exclude fundamental information.
• A recent limit up is not evidence that a stock will continue to perform well.
• The excerpt provides no backtest results or validation of the proposed screen.
