Chinese Stock Screen Combining Price Range, Convertible Bonds, and Volume Activity

Summary

This stock-screening proposal combines a daily price-range condition, the presence of a convertible bond, and a volume-activity measure built from yesterday’s turnover and today’s auction volume relative to yesterday’s volume. The article frames these inputs as signals about price movement, company characteristics, and current market attention. It gives both a formula-style screen and a Python example, but reports no backtest, sample period, or evidence that the rules predict returns.

The author notes that the measures are short-term and sensitive to market sentiment, and suggests adding valuation, growth, and profitability information. The examples are not a reliable specification as written: the formula and Python code appear to implement some conditions differently, and the code has questionable data handling and variable use. The document is best read as a rough screening concept rather than a reproducible or validated strategy; it supplies no trade management or portfolio rules.

Key ideas

• The proposed screen combines price amplitude, a convertible-bond condition, and a volume-related ratio.
• It uses recent turnover and auction activity to represent short-term trading interest.
• The article cautions that short-term volume measures can fluctuate with sentiment.
• The formula and Python example do not appear to implement the same complete rules.
