Small-Cap Stock Screening by Investor Accumulation and Profitability

Summary

The article describes a Chinese equity screen combining a reported daily increase in investor holdings above 5%, free-float market capitalization between 5 billion and 10 billion yuan, total market capitalization below 10 billion yuan, and a requirement that the company has not been loss-making. It interprets rising holdings as possible buying interest and the size limits as a way to focus on smaller companies. The article also proposes adding valuation checks, including price-to-earnings below 20 and price-to-book above 1, plus a check for major negative events during the prior year.

It cautions that a daily holdings measure may reflect short-term sentiment rather than durable business value, and that size restrictions can exclude otherwise attractive firms. The included example code sorts a holdings file and filters market capitalization data, but its event-related filtering and date handling do not clearly implement all the stated screening rules. No backtest, returns, or evidence that the conditions predict performance is reported, so the screen is a proposal rather than a validated strategy.

Key ideas

• The proposed screen combines rising daily investor holdings with small total and free-float market capitalization.
• The article describes excluding companies that have recorded losses.
• It suggests adding valuation ratios and a review of recent negative events.
• The author warns that daily accumulation may reflect sentiment rather than long-term company quality.
• The example code is only a reference and does not clearly implement every stated criterion.
