Screening Stocks with a Morning Star Pattern, Range, and Ten-Day Return

Summary

This Chinese stock-selection note describes a screen requiring daily amplitude above 1, a ten-day price gain greater than zero but below 35%, and a morning-star candlestick pattern. It presents the combination as a way to find stocks with recent positive movement and a potential reversal pattern. The accompanying example code attempts to identify the pattern from recent open, high, low, and close data, although its conditions are not a full, clearly specified definition of a morning star.

The document offers no backtest, benchmark comparison, or evidence that the filters predict returns. It acknowledges that the approach relies mainly on technical data and that past performance does not ensure future results. It suggests adding financial measures, other chart patterns, and sector rotation information. The supplied code also describes a return calculation over a longer data interval than the stated ten-day screen, so the implementation may not match the headline criteria exactly. No entry, exit, or position-sizing rules are specified.

Key ideas

• The screen combines amplitude above 1, a positive but under 35% ten-day return, and a morning-star pattern.
• The example code attempts to infer the candlestick condition from recent price bars.
• The document provides no backtest or evidence for predictive value.
• It warns that the technical screen is narrow and historical performance may not persist.
• The code's return window appears inconsistent with the stated ten-day rule.
