A-Share Quality Screen Using Profit Growth, ROE, and Valuation

Summary

This Chinese-language strategy note tests a simple stock screen for mainland China A-shares. It selects companies using three annual-report criteria: net profit growth above a threshold, return on equity above a threshold for three consecutive years, and a price-to-earnings ratio below a ceiling. For valuation, the author uses the year-end report date where available, otherwise the most recent prior date. The screen produced 43 stocks from one three-year reporting window.

The note reports a one-year historical portfolio test in which an equal amount was invested in each selected stock and performance was compared with the CSI 300. It gives return, annualized return, benchmark return, alpha, and beta figures, but supplies no transaction-cost assumptions, rebalancing details, or fuller methodology. A second application using a later reporting window identifies 34 stocks, but their subsequent performance is not reported. The small historical example does not establish that the screen will generalize or remain effective.

Key ideas

• The screen combines profit growth, sustained return on equity, and a price-to-earnings limit.
• The author uses annual-report data and a nearby prior date when valuation data is unavailable on the report date.
• The first screened portfolio is equally weighted and compared with the CSI 300 over a year.
• A later screen identifies a new group of stocks, but its future performance is not provided.
• The backtest description omits costs and other details needed to assess robustness.
