A-Share Stock Screen Using Price Range and Rising Control Metrics

Summary

This A-share screening idea combines a price-amplitude threshold with measures described as yesterday’s and today’s main-fund control. It seeks stocks with notable price movement and a rising control measure, on the premise that these features may identify active stocks in an upward trend. The document includes formula references and sample Python-style screening logic, but the code’s definitions and implementation details do not fully align with the stated criteria.

The author cautions that the screen omits company fundamentals, may overemphasize current capital-flow signals, and can select volatile stocks exposed to sharp pullbacks. Suggested refinements include adding fundamental and industry context or technical filters such as MACD and KDJ. No historical test, benchmark, or performance evidence is provided, and the control metric is not independently defined, so the proposed relationship between the indicators and future gains remains unvalidated.

Key ideas

• The screen combines price amplitude with measures of prior and current main-fund control.
• Its rationale is that rising control alongside larger price movement may flag active, upward-trending shares.
• The document warns that amplitude can also accompany steep declines and that fundamentals are omitted.
• It suggests adding company, industry, or technical filters, but provides no performance validation.
