Chinese Stock Screening with Amplitude, Convertible Bonds, and Seven Declines

Summary

The document presents a Chinese equity screen combining daily price movement, a nonempty outstanding convertible-bond name, and a sequence of seven declining sessions. It frames the amplitude condition as a measure of volatility, the bond field as a financing or credit clue, and the run of declines as a possible low-entry signal. It also gives example indicator and Python implementations, though the code’s actual conditions do not consistently match that description.

The author warns that relying on a short declining streak can miss long-term value and other company characteristics, and suggests adding technical indicators and fundamental measures such as market capitalization, valuation, and financial condition. No backtest, performance results, or validation are reported. The screen is therefore best understood as an illustrative rule set rather than evidence of a profitable strategy; the mismatch between the stated criteria and examples also makes implementation details important to verify.

Key ideas

• The proposed screen combines price movement, convertible-bond information, and a streak of declining sessions.
• The article interprets consecutive declines as a possible low-entry opportunity, but provides no performance evidence.
• It cautions that this simple rule can overlook company fundamentals and longer-term value.
• Suggested refinements include adding technical indicators and financial or valuation measures.
• The sample implementations should be checked because their conditions do not fully align with the written description.
