Screening Main Board Stocks by Turnover, Float Value, and Prior Low

Summary

The screen targets main board equities with turnover between 3% and 12% and circulating market value between 5 billion and 10 billion yuan. It then compares the latest close with the previous session’s low. The article describes this as a simple short-term stock selection rule and includes formula and Python-style examples for implementing the filters.

The post provides no backtest, return data, benchmark, or evidence that the screen predicts performance. Its discussion notes that relying on a single price comparison can make selections sensitive to daily market fluctuations and may exclude otherwise suitable stocks. It suggests adding fundamental or technical filters, but does not specify or evaluate them. The examples also need careful checking: the stated condition is close above yesterday’s low, while the code and formula shown appear to reverse or misalign that comparison. As written, the rule should be verified before implementation.

Key ideas

• The screen filters main board stocks by turnover and circulating market value ranges.
• It also uses a comparison between the latest close and the previous session’s low.
• The article presents the rule as simple and sensitive to daily price changes.
• Its formula and code examples appear inconsistent with the stated price comparison and should be checked.
• No backtest or performance evidence is provided.
