Screening for Volatile Stocks with Recent Limit-Ups and Positive Weekly MACD

Summary

This Chinese stock screen admits candidates when daily amplitude exceeds 1%, at least one limit-up occurred during the prior 25 days, and weekly MACD is above zero. The rationale is to combine elevated price movement, evidence of recent demand, and a positive medium-term momentum signal. The document includes example indicator and Python implementations, but it does not provide a backtest, portfolio construction rules, trade timing, or measured outcomes.

The source identifies several limitations: technical and historical price data can omit company fundamentals; broad market declines can undermine individual signals; and MACD may lag price changes. It suggests considering financial statements and industry context, conditioning entries on market direction, combining other indicators, and diversifying positions. These are general risk and refinement suggestions, not empirically validated enhancements. The screen is best understood as a candidate-selection rule; the examples may also differ in how they implement the recent limit-up and weekly MACD conditions.

Key ideas

• The screen combines amplitude above 1%, a limit-up within the previous 25 days, and weekly MACD above zero.
• Its rationale joins volatility, recent market enthusiasm, and a positive trend signal.
• The document provides code examples but no performance evidence or full trading rules.
• It warns about fundamental blind spots, market-wide declines, and MACD lag.
• Suggested refinements include market context, fundamental data, additional indicators, and diversification.
