Screening A-Shares by Daily Range, Circulating Shares, and Region
Summary
This proposed A-share screen selects stocks whose daily high-low range exceeds 1%, excludes Beijing-listed shares, and caps circulating share capital at 5.5 billion shares. The document frames these conditions as filters for recent price movement, region, and float size, and includes formula and Python examples for applying them. It also discusses possible extensions such as valuation, return on equity, technical patterns, and trend analysis.
No test results, historical returns, or rationale for the specific thresholds are provided. The post notes that a one-day range may say little about future direction, that a small-float focus can omit larger companies, and that excluding a region may overlook opportunities. The examples and suggestions therefore describe a screening concept rather than a demonstrated trading strategy; the parameters and signal behavior would need careful verification and testing before use.
Key ideas
- The proposed screen requires a daily high-low range above 1%, excludes Beijing shares, and limits circulating shares to 5.5 billion.
- The conditions combine a short-term price-range filter with regional and float-size constraints.
- The document gives formula and Python examples but presents no performance evaluation.
- It notes that one day's range may not indicate future direction and that the regional exclusion may be overly broad.
- Suggested enhancements include fundamental measures and additional trend or technical filters.
