A-Share Screen for Recent Position Increases and Mid-Range Float Value

Summary

The document describes a simple Chinese A-share stock screen combining recent position-increase share with circulating market capitalization. It selects stocks whose reported increase for the day exceeds 5% and whose circulating value falls between 5 billion and 10 billion yuan, with the post title also specifying the 2021 period. The supplied pseudocode repeats those two selection conditions; it does not describe portfolio weighting, entry timing, exits, or position sizing.

The author identifies possible weaknesses: position-increase data may be manipulated or fail to reflect actual investor activity, and circulating market capitalization is only an imperfect proxy for liquidity. Suggested refinements include adding turnover and valuation measures and drawing on additional data sources. No backtest, performance evidence, data definitions, or validation procedure is provided, so the screen should be treated as a proposed filter rather than an evaluated strategy. The relationship between the stated 2021 period and the “today” signal is not further explained.

Key ideas

• The screen combines a daily position-increase threshold with a circulating market capitalization range.
• The post title specifies trading during 2021, but the selection logic does not explain how the date restriction is applied.
• Position-increase data may be unreliable or manipulable.
• Circulating market capitalization does not by itself establish that a stock is sufficiently liquid.
• Turnover, valuation measures, and additional data sources are proposed as possible refinements.
