Chinese Stock Screening with Bond Listing, Daily Range, and 250-Day Trend

Summary

This Chinese equity screening example combines a daily price-range threshold, the presence of an outstanding convertible-bond name, and a close above the prior 250-day moving average. It presents the moving-average condition as a way to favor stocks in a long-term uptrend and treats larger daily swings as a source of both opportunity and risk. The document also includes a formula reference and a Python example, though the implementation does not fully align with the stated bond-name condition.

The author warns that the screen can still select stocks in persistent declines and suggests adding financial, industry, and sentiment measures. No backtest, performance figures, or selection results are supplied, so the stated rationale is qualitative. The rules describe a stock-selection filter rather than a complete trading system: entry timing, portfolio construction, and risk controls are not specified.

Key ideas

• The screen requires daily amplitude of at least one percent and an outstanding convertible-bond name.
• It selects stocks whose latest close is above the previous 250-day moving average.
• The document frames this long moving-average filter as evidence of an extended upward trend.
• It cautions that the screen may still include stocks in prolonged declines.
• It proposes adding financial and market context, but provides no empirical results.
