Chinese Stock Screening with Volatility, Volume, Gap-Up, and KDJ Filters
Summary
The document outlines a Chinese equity screening approach that combines price movement, trading activity, opening price, and a rising KDJ K value. It aims to find stocks showing notable intraday movement and volume alongside a short-term technical signal. A sample formula also includes a circulating market capitalization threshold. The accompanying Python example describes retrieving daily and basic stock data and checking for some of these conditions.
The article recommends supplementing technical filters with valuation and profitability measures, such as price-to-earnings, price-to-book, and return on equity, plus broader company and market context. It gives no performance results or evidence that the screen predicts returns. Its formula and code examples also differ in how they express the opening-price condition, and the code does not implement every criterion described. Treat it as a screening concept that needs clarification and testing, not as a validated strategy.
Key ideas
- The screen combines a minimum amplitude and trading volume with a gap-up condition and rising KDJ K value.
- A sample formula adds a circulating market capitalization threshold.
- The article suggests combining technical signals with valuation and profitability measures.
- No backtest evidence is provided, and the formula and code examples do not fully match.
