Screening Chinese Stocks by Short-Term Returns and Auction Moves

Summary

This post describes a Chinese A-share screening rule using three conditions: the day’s increase in buying-position share must exceed five percent, the opening auction price change must be between minus two and five percent, and the ten-day return must be above zero but below thirty-five percent. It presents the conditions as a way to find stocks with positive recent performance and active buying, while limiting the size of the recent gain and the auction move.

The post also outlines a simple stock-by-stock implementation and suggests adding financial fundamentals and price or volume analysis. It provides no backtest, performance figures, market regime analysis, or precise data definitions for the buying-share and auction measures. The rationale is therefore a screening hypothesis rather than evidence of profitability. Its own risk discussion notes that the rule omits longer-term trends and company fundamentals, and that past market behavior may not predict future returns.

Key ideas

• The screen combines buying-share, opening-auction change, and ten-day return conditions.
• It targets stocks with positive but bounded recent returns and a limited auction move.
• The post supplies a basic implementation outline but no performance evidence.
• The rule omits fundamentals and longer-term trend information, which may affect results.
