Screening Chinese Equities by Range, Opening Gain, and Institutional Holdings

Summary

This post describes a Chinese equity screening rule that combines a price-range condition, a cap on the opening auction’s gain, and a minimum institutional ownership ratio. It presents these criteria as a way to reflect short-term price movement and capital flows, then suggests applying further fundamental and technical filters before building a final candidate list. The example also mentions moving averages and MACD as possible additions, along with explicit trading rules and stop-loss controls.

The post includes a formula-style illustration and a Python example that queries stock, daily price, tick, and shareholder data before filtering candidates. However, the implementation has apparent inconsistencies: its range calculation checks whether the high-to-low ratio is at most one, and its opening-price condition does not exactly match the stated strict threshold. The article supplies no backtest results or evidence that the screen is profitable. It warns that sentiment and money flows can make the approach vulnerable to chasing crowded trades, and that performance may weaken in adverse markets.

Key ideas

• The proposed screen combines stock price range, opening auction performance, and institutional ownership.
• The author suggests applying additional fundamental and technical filters to the initial candidate pool.
• Possible enhancements include moving averages, MACD, trading rules, and stop-loss controls.
• The sample code contains apparent mismatches with the written screening conditions and needs careful validation.
• The post gives no performance evidence and notes that market sentiment and adverse conditions can impair results.
