Screening Chinese Stocks by Auction Flows and Control Measures

Summary

This post proposes a Chinese A-share stock screen combining price movement, a measure of daily control, and buying activity in large and very large orders during the auction. It also suggests adding a dividend yield or PEG condition. The rationale is to identify stocks with notable short-term movement and buying pressure; the article characterizes the resulting candidates as potentially high risk and high return.

The post warns that auction price changes can be noisy, large-order statistics may be distorted by market conditions or manipulation, and a short-term flow screen does not establish long-term investment value. It recommends supplementing the signals with company fundamentals, valuation or growth measures, market-flow or sentiment analysis, and risk controls. Although indicator formulas and code examples are included, no backtest, benchmark, or measured performance is reported, and some formula details may not map cleanly to the prose criteria.

Key ideas

• The proposed screen combines price amplitude, a daily control measure, and large-order buying during the auction.
• A refinement adds a dividend yield or PEG filter to the short-term flow conditions.
• Auction movements and large-order data can be noisy or vulnerable to manipulation.
• The post offers no performance test, so the screen’s effectiveness is not established.
