Equity Screening with Range, Free-Float Market Cap, and MACD

Summary

This stock screen combines three filters: daily price range of at least 1 percent, free-float market capitalization above 10 billion yuan, and a MACD reading above zero. The article frames these as measures of trading activity, company scale, and technical trend, and provides example formula and data-query implementations. It also suggests considering company fundamentals, other indicators, industry conditions, and portfolio risk controls alongside the screen.

The document reports no backtest results or evidence that the filters produce persistent excess returns. Its claims about strategy performance are not supported with sample details, dates, transaction costs, or risk statistics. The discussion recognizes that a positive MACD can mislead and that a large-capitalization screen may not suit every investor. Implementation details should be checked carefully: the stated range and market-cap thresholds need consistent units, and the example code’s indicator and sampling steps are not fully explained.

Key ideas

• The screen requires a minimum daily range, a large free-float market capitalization, and MACD above zero.
• The filters combine a price-activity measure, a size threshold, and a trend indicator.
• The article provides example implementations but no documented backtest or performance evidence.
• Fundamental analysis, portfolio exposure, and risk controls are suggested as additions to the screen.
