Screening Chinese Equities with Limit-Down Open Signals and Profit Growth

Summary

The document outlines a Chinese equity screening rule combining a daily amplitude threshold, a previous session’s 9:15 matched price at the limit-down level, and year-over-year net profit growth attributable to parent-company shareholders within a specified range. Its final version adds a rising 60-day moving average. The article suggests that the early matched price may reflect market sentiment, while profit growth and the moving-average direction add fundamental and trend filters. It also describes sorting qualifying stocks by total market value and selecting a requested number.

The post supplies indicator expressions and illustrative code, but it does not present backtest results or define key implementation details such as data timing, survivorship treatment, or transaction costs. It cautions that profit figures may have valuation-related issues and that market uncertainty prevents guaranteed returns. It recommends adding valuation measures, other indicators, sector and policy analysis, and controls such as stops and position limits. The screening rationale is therefore a hypothesis requiring independent validation.

Key ideas

• The screen combines daily amplitude, a prior limit-down matched-price condition, and profit growth between the stated bounds.
• The final rule also requires the 60-day moving average to rise.
• Qualifying stocks are ranked by total market value before a requested subset is selected.
• The article gives implementation references but no evidence from a backtest.
• It recommends broader fundamental analysis and risk controls before using the screen.
