Stock Screening with Amplitude, Control Changes, and MACD

Summary

This stock-selection idea combines three daily conditions: amplitude above one, a controlling-shareholder control measure above 21 in absolute value, and MACD above its zero line. The post frames amplitude as a volatility filter, the control measure as an indicator of capital activity, and positive MACD as a sign of upward momentum. It includes example implementations in a Chinese stock-screening formula language and Python, though the snippets are reference material that may need adjustment for a particular data platform.

The document offers no backtest, benchmark, or evidence that the screen predicts returns. It cautions that technical filters can overlook company fundamentals and broader market conditions. Suggested additions include market heat and money flows, fundamental measures such as earnings and returns on equity, and other technical indicators. Those proposed extensions are not evaluated, and the meaning and data quality of the control measure are not explained in depth.

Key ideas

• The screen requires amplitude above one, an absolute controlling-shareholder control measure above 21, and MACD above zero.
• The post interprets the conditions as filters for volatility, capital activity, and positive momentum.
• It provides example implementations in a platform formula language and Python.
• The document reports no performance testing or evidence of predictive value.
• It recommends considering fundamentals, market conditions, and other indicators, without testing those additions.
