Screening Robot-Themed Chinese Stocks with MACD and Market-Cap Filters

Summary

This post outlines a Chinese equity screen for robot-themed stocks. It combines amplitude above 1, a circulating market capitalization below 10 billion, and a MACD condition described as being above the zero axis. The accompanying explanation presents the amplitude filter as a way to focus on moving stocks, the theme filter as exposure to robotics, and the size limit as a way to include smaller companies. It also describes MACD as a trend indicator based on differences between shorter- and longer-term moving averages.

The post includes example indicator logic and Python-style screening steps, but offers no backtest results, sample definition, or evidence that the combined filters produce an advantage. Its examples use MACD greater than its signal line, which is not necessarily equivalent to MACD being above zero; the implementation detail therefore merits verification. The author flags indicator lag, dependence on market conditions, concentration in a single theme, and the risk of neglecting fundamentals. Suggested safeguards and broader analysis are recommendations rather than tested parts of the screen.

Key ideas

• The proposed screen combines amplitude, robot-theme membership, circulating market capitalization, and a MACD trend condition.
• The post presents MACD as a moving-average-based indicator that can lag price changes.
• The sample implementation compares MACD with its signal line, which differs from a strict above-zero test.
• The post provides no backtest evidence and cautions against relying only on technical and thematic filters.
