Small-Cap A-Share Screening with Short-Term MACD and Capital Strength

Summary

This A-share screening concept combines a market-cap ceiling of 10 billion yuan with high capital strength, ranked from stronger to weaker, and a 15-minute MACD histogram that is shrinking while below zero. The article interprets the contracting negative histogram as weakening bearish pressure. It proposes combining that signal with other indicators, such as Bollinger Bands and RSI, and considering broader market conditions before selecting stocks.

The document notes that smaller companies may have limited liquidity and market attention, and that a shrinking MACD histogram can give misleading signals when used alone. It includes only a minimal code sketch for filtering by market capitalization; it does not implement the full signal, define capital strength precisely, or provide backtest results. The discussion offers a screening hypothesis and general cautions rather than evidence that the conditions predict gains. Its proposed fundamental and market-context checks are not developed into measurable rules.

Key ideas

• The screen combines a market-cap ceiling of 10 billion yuan with capital-strength ranking and a 15-minute MACD signal.
• A shrinking negative MACD histogram is treated as a sign that bearish pressure may be easing.
• The article suggests adding indicators such as Bollinger Bands and RSI and accounting for market conditions.
• It warns that small-cap stocks may be less liquid and that MACD alone can produce false signals.
• The code sketch does not implement the full strategy, and no backtest evidence is reported.
