Screening Stocks for Volatility, a Morning Star Pattern, and Recent Limit-Ups

Summary

This note outlines a technical stock screen that combines price amplitude above a threshold, a named morning star candlestick condition, and at least one limit-up event in the prior month. It frames high amplitude as evidence of price movement and a recent limit-up as a sign of market attention, then suggests examining selected stocks further. Formula and Python examples are included as implementation references.

The document provides no backtest results or evidence that the combination predicts returns. It warns that volatile stocks carry greater risk and that limit-up moves may reflect speculative activity and changing market sentiment. The examples do not clearly implement every stated condition: the Python excerpt checks some different price and candle properties, and the formula’s pattern condition is not explained. The note suggests supplementing the screen with other indicators, fundamentals, market-trend assessment, and periodic testing.

Key ideas

• The proposed screen combines high price amplitude, a morning star pattern, and a recent limit-up event.
• The author treats volatility and limit-up activity as possible signs of opportunity and market attention.
• The document supplies example formulas but no performance results.
• The code examples do not clearly match all of the stated screening conditions.
• Volatile shares and speculative limit-up moves can carry elevated risk.
