A-Share Screen Combining Buying Activity, Profit Growth, and Limit-Ups

Summary

This Chinese equity screening idea combines reported net profit growth, an estimate of current buying interest, and a history of limit-up moves. Its stated criteria require buying activity above 5%, year-over-year net profit growth above 20% and no more than 100%, and at least two limit-ups in the previous 500 days. The proposed final screen adds valuation caps of a price-to-earnings ratio below 20 and a price-to-book ratio below 2.

The article argues that these filters may capture investor attention, improving profitability, and strong market interest. It warns that buying-activity measures and financial statements can be manipulated, and that limit-up events may reflect price manipulation rather than durable demand. It suggests broadening the analysis with further valuation and technical factors. The included data-provider code is illustrative and appears internally inconsistent in places, so it should not be treated as a reliable implementation. No backtest, portfolio construction rules, or returns are reported.

Key ideas

• The screen combines a buying-activity threshold, capped year-over-year profit growth, and multiple limit-up events.
• The proposed final criteria also limit price-to-earnings and price-to-book ratios.
• The author treats buying activity, earnings growth, and limit-ups as signals of interest and business improvement.
• The note warns that activity data, reported earnings, and price moves may be misleading or manipulated.
• No performance evidence is supplied, and the sample implementation may not implement the screen correctly.
