A-Share Screening with 15-Minute MACD and Capital-Flow Strength
Summary
This note describes an A-share screening idea combining a ranking by capital-flow strength, a 2021 performance filter, and a 15-minute MACD condition in which the negative histogram bars are shortening. The proposed interpretation is that stronger inflows signal investor attention, prior-year performance may indicate potential, and contracting negative bars may suggest improving short-term momentum.
The document also flags risks: unusually strong inflows may reflect crowding, historical performance does not establish future prospects, and the MACD signal may fail to mark a lasting trend change. It suggests adding measures of flow persistence and size, company and industry fundamentals, volume, and other technical indicators. The selection description is incomplete at its final step, gives no backtest or performance evidence, and does not define how the historical-year filter or capital-flow measure is calculated.
Key ideas
- The screen ranks stocks by capital-flow strength and includes a filter based on performance in 2021.
- A shortening negative MACD histogram on a 15-minute chart is treated as a possible sign of improving short-term momentum.
- Strong inflows can indicate crowding and may not be a reliable standalone signal.
- The document proposes combining flow measures with fundamentals, volume, and other indicators.
- No empirical results or fully specified final selection rule are provided.
