Screening Main-Board Stocks by Turnover, Daily Gains, and ROE

Summary

This Chinese stock-selection post describes a screen for main-board shares with turnover between 3% and 12%, a daily gain above 1%, and return on equity above 15% in each of the most recent five years. It combines recent market strength and trading activity with a persistent profitability measure. The post provides a brief rationale and sample indicator and Python snippets to illustrate selection, rather than a complete, validated trading system.

The author notes that relying on ROE and price activity alone omits other financial risks and business measures. Requiring five consecutive years of high ROE may also leave few candidates and increase slippage risk. Suggested refinements include adding valuation and other technical or fundamental indicators, industry context, and money management, with selection rules adjusted to market and portfolio conditions. No historical performance results or backtest evidence are provided, and the sample code's data and screening details would need validation before use.

Key ideas

• The screen combines main-board membership, turnover between 3% and 12%, and a daily price gain above 1%.

• The approach pairs recent market strength with a multi-year profitability filter.
• The post warns that a narrow set of criteria may omit financial risks and increase slippage.
• It suggests adding valuation, industry, technical, and portfolio management considerations.
