Small-Cap Profitability Screen with Institutional Buying Activity

Summary

This Chinese equity screen seeks companies with market capitalization below 10 billion yuan, no reported past losses, and institutional net buying above a stated 5% threshold. The intended idea is to combine a small-company profile and a basic profitability filter with evidence of institutional demand. The note describes net flow as institutional buying amount, but does not define the measurement period or explain precisely how the percentage relates to total trading volume.

The article acknowledges that this narrow screen ignores factors such as industry conditions and broader financial health, and may exclude promising firms that fail its criteria. It suggests adding financial and industry analysis as well as price and volume indicators. The sample implementation instead selects stocks above the fifth percentile of net flow, which is not equivalent to the stated 5% of total trading volume condition; the code therefore does not faithfully implement the described rule. No historical test or evidence of predictive performance is reported.

Key ideas

• The proposed screen combines market capitalization below 10 billion yuan with no past losses.
• It adds an institutional net-buying threshold described as above 5 percent.
• The measurement period and denominator for the flow condition are not specified.
• The sample code uses a net-flow percentile cutoff that differs from the stated rule.
• The article recommends adding financial, industry, and market analysis but reports no test results.
