Screening Chinese Stocks for Reversals, Volatility, and Recent Limit-Ups

Summary

This document describes a Chinese equity screening rule combining daily price range, a reversal pattern, and a recent limit-up. Its refined version looks for a range above 1%, a reversal pattern within the latest three trading days, and at least one limit-up during roughly the past month. The author provides formula and Python examples intended to implement these filters, including a candlestick indicator as a proxy for the reversal condition.

The rationale is that larger price swings and a reversal may indicate a short-term opportunity, while a recent limit-up may signal strong market attention. The post offers no backtest, performance figures, or evidence that these signals predict returns. It cautions that the screen relies heavily on price action, omits company fundamentals, and does not initially specify limit-up frequency; suggested refinements include market context, fundamentals, and more precise limit-up filters. The supplied formulas and examples may not perfectly match the stated conditions, so their implementation should be checked before use.

Key ideas

• The refined screen combines a price range above 1% with a recent reversal pattern and a limit-up in the past month.
• The author presents formula and Python examples for applying the filters to Chinese equities.
• The proposed rationale is that volatility, reversal behavior, and recent price strength may identify active candidates.
• The post provides no performance test or evidence of predictive value.
• It warns that the screen omits fundamentals and leaves some limit-up details underspecified.
