Screening Chinese Stocks by Volatility, Declines, and Trading-List Appearance

Summary

This stock screen selects shares with daily amplitude above one, a decline between four and five percent on the current day, and an appearance on the prior day’s Dragon Tiger List. The article presents this as a way to find volatile, actively traded stocks and discusses the list as a possible signal of market attention. It supplies example indicator logic and Python-style implementation guidance, but reports no backtest, return data, or evidence that the screen predicts profitable trades.

The stated caveats are that leaderboard activity may not reflect business quality or earnings, and that relying on a few technical or financial measures can make a strategy unreliable. Suggested refinements include adding fundamental, industry, and risk controls such as stop levels and position sizing. The implementation details should be interpreted cautiously: the article itself says adaptation may be needed, and its sample data calls may not ensure that the listed observations correspond to the intended historical dates.

Key ideas

• The screen combines elevated daily amplitude, a decline within a specified band, and a prior-day Dragon Tiger List appearance.
• The leaderboard condition is intended to identify stocks attracting unusual market attention.
• The article provides sample formulas and implementation guidance but no performance evaluation.
• Leaderboard turnover does not establish company quality or future returns.
• Fundamental checks, stop levels, and position sizing are suggested as additional safeguards.
