A-Share Stock Screening by Recent Position Increases and Company Year

Summary

The stated screen selects stocks with a position-increase ratio above 5% for the day and an enterprise attribute described as 2021. The article frames the first condition as a sign of recent capital inflow, but the meaning of the company-year condition is unclear. Its proposed code does not cleanly implement the stated rule: it substitutes rising short- and long-term momentum measures, filters a year field, and ends with an incomplete market-cap condition. This gap makes the operational method difficult to reproduce from the document.

The article cautions that relying on a single day’s activity may favor short-term strength without capturing longer-term company performance, and that broad market swings can undermine the selection. It suggests adding valuation or size filters and longer-horizon fundamental and technical analysis. It provides no backtest or measured results, so the screen should be considered an incomplete idea rather than an evaluated strategy.

Key ideas

• The stated selection condition is a daily position-increase ratio above 5% alongside an enterprise attribute labeled 2021.
• The accompanying code instead uses short- and long-term momentum changes and is incomplete.
• A single day of position activity may not reflect a company’s longer-term prospects.
• The article provides no backtest or performance results.
