Robot-Themed Stock Screen Using Weekly MACD and Volatility

Summary

The document proposes screening Chinese equities for daily amplitude above 1%, weekly MACD above zero, association with the robotics theme, and circulating market value below 10 billion yuan. It presents amplitude and MACD as measures of price movement and trend, while the industry and market-cap filters narrow the universe. Formula and Python examples are included, although the code does not clearly calculate weekly MACD and the stated formula conventions may require adaptation to the data source.

The article identifies missing valuation analysis, the breadth of the robotics category, and changing market conditions as limitations. It recommends incorporating valuation and company fundamentals, choosing relevant robotics subsectors, and reviewing whether the rules remain suitable across market regimes. The document gives no backtest, return data, or evidence that this screen outperforms a benchmark; the proposed filter is therefore an idea for further testing rather than a validated strategy.

Key ideas

• The proposed screen combines daily amplitude, weekly MACD, robotics-sector membership, and a circulating market-cap ceiling.
• The article uses MACD as a trend filter and amplitude as a measure of price movement.
• The sample code may not faithfully implement the stated weekly MACD condition.
• Valuation, company fundamentals, and robotics subsector selection are suggested as additional filters.
• No performance test or evidence of predictive value is provided.
