A Chinese Stock Screen Combining Limit-Down Prices and Rising Lows

Summary

The document describes a Chinese equity screening idea that combines a large daily range, a prior-day opening auction price at the limit-down level, and a rising-bottom condition. Its final version adds a price-to-earnings threshold and volume above the five-day average, then ranks candidates by popularity. The conditions are presented as a technical screen intended to find stocks whose recent lows are improving after a severe price event.

The article provides indicator expressions and a sample implementation, but it offers no backtest, return series, or evidence that the screen predicts gains. It explicitly cautions that chart-based signals can lag, may generate false positives, and omit other market and company information. It suggests adding technical and fundamental variables or using a multifactor or machine-learning approach, but supplies no evaluation of those alternatives. The implementation also relies on platform-specific functions, so the stated logic may need adaptation before it can be applied consistently.

Key ideas

• The proposed screen combines a large price range, a prior-day limit-down auction price, and a rising-bottom signal.
• The final selection conditions also require a price-to-earnings ratio below the stated threshold and volume above its five-day average.
• Candidates are ranked by stock popularity, although the document provides no evidence that this ranking improves performance.
• The author warns that simple chart patterns can lag and produce false signals.
• The screen omits broader factors, and the document provides no backtest or performance results.
