Screening Chinese Stocks with Volatility, MACD, and Concentration

Summary

This stock-screening proposal combines three conditions: daily price amplitude above a threshold, a shrinking negative MACD histogram on a 15-minute chart, and a low concentration measure. The text interprets high amplitude as evidence of volatility and a contracting negative MACD histogram as a possible sign that price direction may be changing. It suggests that low concentration could identify stocks with potential for a sharp move.

The author cautions that low concentration may also signal weak liquidity or limited market interest, and that screening on a few indicators can miss important context. The proposal recommends adding company fundamentals, industry themes, and policy developments before making a selection. It gives sample formula and data-processing references, but the examples contain inconsistencies in how amplitude and concentration are defined and filtered, so the screen's implementation is unclear. No backtest, performance results, or evidence that the conditions predict returns are provided; the screen is best understood as an unvalidated idea requiring careful definition and evaluation.

Key ideas

• The proposed screen combines price amplitude, a contracting negative 15-minute MACD histogram, and a concentration filter.
• The text treats high amplitude as a volatility signal and MACD contraction as a possible shift in price movement.
• Low concentration may coincide with poor liquidity or weak market interest.
• The author recommends adding fundamental and market context to indicator-based screening.
• The sample implementation is internally inconsistent, and no performance evidence is presented.
