Chinese Stock Screening with Profit Growth, Revenue Growth, and Buying Activity

Summary

This stock screen combines a buying-activity condition, year-over-year growth in net profit attributable to parent shareholders, and a revenue comparison across two reported years. The article initially specifies profit growth above 20% and up to 100%, with revenue in 2021 exceeding revenue in 2018 by a stated ratio. Its final suggested logic narrows the profit-growth range to 20%–50% and adds valuation checks and longer-term revenue growth measures.

The article argues that the filters represent capital inflow, profitability, and business growth, while cautioning that buying activity may be short-lived and growth rates can be unstable. It gives a code example but no backtest or measured performance. The code’s valuation thresholds are examples, not supported by results, and the suggested optimization introduces conditions beyond the initial screen. The two descriptions therefore do not define one fully consistent strategy; data timing, fiscal-period comparability, and the meaning of the buying-activity measure would need to be specified before testing.

Key ideas

• The proposed screen combines buying activity with net-profit growth and revenue growth.
• The initial profit-growth band is above 20% and no more than 100%, while the final version suggests 20%–50%.
• The final suggestion adds valuation and longer-term revenue-growth checks.
• The article warns that buying activity can reflect short-term speculation and growth may not remain stable.
• No performance evidence is supplied, and the initial and final rule descriptions differ.
