Stock Screening with a Morning-Star Pattern, Range, and Float Size

Summary

This post proposes a Chinese stock screen that combines a daily range above one percent, a morning-star candlestick condition, and a limit on circulating share capital. It presents the pattern as a technical signal and the float constraint as a size-related filter, then suggests adding sector context and other analysis. The post also provides formula and Python examples intended to identify candidates.

The implementation details do not cleanly match the stated rules: the formula refers to circulating market capitalization, while the Python checks total market value within a range and adds filters involving recent prices, moving averages, and volume. The description also does not define a standard morning-star pattern in enough detail to reproduce it consistently. No backtest or return evidence is offered. The post notes that past performance may not persist and that shares with a smaller float may face concentrated selling, but it does not quantify these risks.

Key ideas

• The proposed screen combines a price-range threshold, a morning-star pattern, and a circulating-share constraint.
• The post presents the pattern as a technical condition and float size as a company-size consideration.
• The formula and Python example use different size measures and include differing conditions.
• The pattern definition and evidence for the strategy are limited, so the screen would need careful specification and validation.
