Screening Chinese Stocks for Volatility, Recent龙虎榜 Activity, and Seven Declines

Summary

The article describes an equity screen combining three conditions: a prior-day trading range above a stated threshold, appearance on the previous day’s 龙虎榜 (a public list associated with unusual trading activity), and closing prices falling for seven consecutive sessions. The proposed rationale is to find weak-trending stocks that might be undervalued or due for a rebound, while the range and list conditions are intended to flag volatility and notable capital activity. It provides example logic in a charting formula format and Python, along with a brief outline of risks and possible refinements.

The article offers no backtest, return data, or evidence that the selected stocks are undervalued or will rebound. It notes that the screen overlooks company finances and growth prospects and may miss short-term opportunities. The examples also leave implementation details to verify, including how the list data and consecutive-decline condition align by date. Valuation measures and fundamental review are suggested as additional checks, not as validated improvements.

Key ideas

• The screen combines a volatility threshold, prior-day 龙虎榜 appearance, and seven consecutive lower closes.
• The author frames prolonged declines as a possible source of rebound candidates, rather than evidence of undervaluation.
• Example selection logic is supplied in charting-formula and Python styles.
• The article gives no backtest or performance evidence for the screening rules.
• Fundamental health and the alignment of market data by date require separate review.
