Screening Chinese Stocks by Trading Activity, Opening Price, and ROE

Summary

The document describes a Chinese equity screen combining daily price movement and trading activity with a profitability filter. It selects stocks with an amplitude above 1, current volume above 10,000 lots, a higher opening price, and return on equity above 15% for five consecutive years. The accompanying explanation treats the market activity conditions as signs of liquidity or short-term opportunity and the ROE condition as a measure of sustained profitability. It also suggests adding valuation measures, industry context, and trend information.

The article provides an indicator formula and a Python example, but the example does not clearly implement all stated conditions: it checks a recent ROE value and includes moving-average filters, while the formula gives a separate set of conditions. No backtest results or performance evidence are reported. The screen also risks treating different industries alike and relies on a narrow set of indicators; the article itself notes that ROE benchmarks vary by industry and recommends considering other financial and market factors.

Key ideas

• The proposed screen combines amplitude, trading volume, opening price, and a five-year profitability condition.
• High trading activity is used as a liquidity filter, while sustained ROE is intended to identify profitable firms.
• The article recommends adding valuation measures, industry context, and trend analysis.
• The supplied formula and Python example do not fully align, and no performance results are presented.
