Chinese Stock Screen Combining Price Amplitude, Limit-Ups, Size, and Profitability

Summary

This Chinese equity screen combines daily price amplitude above 1, at least one limit-up event during the prior month, and an initial market-cap ceiling of 10 billion yuan with a requirement that the company has no losses. The article then revises the proposed rule: its final screen uses a market-cap range of 5 billion to 20 billion yuan and positive net profit in the latest quarter, alongside the amplitude and recent limit-up conditions. It also describes sorting qualifying stocks by market capitalization and selecting a limited set.

The screen mixes short-term price activity with company size and profitability, but the article reports no backtest or performance evidence. It cautions that a size band may exclude stocks outside it, that industry and market conditions are omitted, and that a single quarter does not capture long-term finances or management quality. Suggested refinements include revenue growth, industry context, and broader market conditions. The article’s initial and final criteria differ, so the revised conditions should be distinguished from the original headline rule.

Key ideas

• The initial screen combines amplitude above 1, a recent monthly limit-up, market capitalization below 10 billion yuan, and no losses.
• The revised screen uses a market-cap range of 5 billion to 20 billion yuan and positive latest-quarter net profit.
• The proposed filters combine short-term price behavior with size and company profitability.
• The article flags missing industry, market-regime, and longer-term business-quality considerations.
• It provides no reported backtest or evidence that the screening rules predict returns.
