Chinese Stock Screening with Volatility, Ten-Day Gains, and Weekly MACD

Summary

This stock selection proposal combines three technical filters: an intraday range above a threshold, a positive ten-day return capped below a stated upper bound, and weekly MACD above its zero line. The article presents volatility as a way to identify active shares, the bounded return as a way to avoid both declining and already sharply advanced stocks, and positive weekly MACD as a trend confirmation. It recommends adjusting the screen with additional technical, fundamental, and market context. The indicator formula and Python sketch are incomplete or inconsistent with parts of the written criteria, including the weekly time frame and stated return bounds.

The page provides no backtest, sample description, or performance evidence. It notes that a small number of filters cannot capture company characteristics or changing market conditions, and that corporate actions such as insider or institutional selling can affect outcomes. Its suggestions to use longer windows and add fundamentals are general rather than tested. The screen should therefore be treated as an idea for research, with its calculations and data frequencies clarified before evaluation.

Key ideas

• The screen combines intraday volatility, a bounded positive ten-day return, and weekly MACD above zero.
• The article uses MACD as a trend filter and the return band to restrict recent price performance.
• It cautions that few technical conditions omit fundamentals and may miss important market or company changes.
• The provided formula and code do not fully specify or consistently implement the written screening rules.
