Screening Chinese Stocks for Turnover, IPO Year, and Intraday Losses

Summary

This note describes a Chinese equity screen using three characteristics: turnover between 3% and 12%, an IPO year of 2021, and a specified daily maximum decline between 4% and 5%. It presents the rules as a way to identify stocks based on trading activity, listing vintage, and short-term price weakness. It also sketches indicator logic and a data-processing example, but does not report selected stocks, a backtest, or measured returns.

The author cautions that focusing on short-term price action may produce volatile candidates and encourage excessive trading. The screen uses few inputs and omits company fundamentals and broader technical context; the note suggests incorporating both. The indicator description and sample code do not consistently implement the stated daily maximum-decline condition, and other sample calculations appear unrelated to the target screen. Those discrepancies limit the code’s usefulness. The rules should be treated as a rough screening concept requiring data and logic validation, not as evidence of a profitable approach.

Key ideas

• The screen combines 3%–12% turnover, a 2021 listing year, and a daily maximum decline in the 4%–5% range.
• The method selects on trading activity and short-term price behavior without reporting performance evidence.
• The note flags volatility and overtrading as risks of relying on short-term signals.
• It recommends adding fundamental and technical factors for a broader assessment.
• The sample indicator and code do not clearly match the stated screen and require validation.
