Screening Chinese Stocks by Fund Flows, Price Change, Size, and Profitability

Summary

This proposed equity screen combines several filters: a reported increase in position holdings above 5%, a price change below 2.6% and above -5%, market capitalization no greater than 10 billion yuan, and a history without losses. The post interprets the flow condition as evidence of recent buying interest and the bounded price move as a stability filter. It suggests ranking or narrowing qualifying companies further with valuation measures such as price-to-earnings and price-to-book ratios.

The post gives a screening rationale and a code reference, but no backtest results, time horizon for the filters, or precise data definitions. It warns that the constraints may omit companies with strong longer-term records and may make the screen overly conservative. The strategy is a proposal rather than demonstrated evidence of predictive value; readers would need to clarify the flow and profitability data, test the rules across periods, and account for trading costs and selection bias before drawing conclusions.

Key ideas

• The proposed screen requires reported position growth above 5% and a price change between -5% and 2.6%.
• It restricts the universe to companies valued at no more than 10 billion yuan with no historical losses.
• The post proposes using lower valuation ratios to refine the qualifying stocks.
• The author notes that the filters may exclude strong companies and produce a conservative universe.
• No performance evidence or complete measurement definitions are provided.
