Chinese Equity Screening with Amplitude, Share Control, and Fundamentals

Summary

This Chinese equity screening proposal starts with daily price amplitude above 1, a measure labeled today’s control above 21, and a concentration condition written as 70 below 20%. Its proposed refined version adds dividend yield and return on equity rankings in the top half of the stock universe. The post presents amplitude and the control measure as indicators of short-term activity, while the concentration filter is intended to screen ownership or shareholding concentration. It includes formula and Python sketches for applying the filters and ranking selected shares.

The document warns that a fixed concentration threshold may exclude companies for which concentrated ownership is normal or beneficial, and that amplitude can be driven by company events rather than a repeatable trading signal. It recommends adjusting thresholds by industry and considering additional fundamentals. No historical test, benchmark, or return evidence is provided, so the suggested refinements remain unvalidated. The meaning and calculation of the “control” and concentration fields are platform-specific, and the descriptions do not fully resolve how those measures should be interpreted or compared across securities.

Key ideas

• The initial screen combines daily amplitude, a share-control measure, and an ownership concentration threshold.
• The proposed refinement adds dividend yield and return on equity rankings in the upper half of the universe.
• The post identifies sector differences and event-driven price swings as potential sources of screening error.
• It suggests adapting concentration thresholds by industry and adding other fundamentals.
• The document provides no performance test, and key platform-specific measures are not fully defined.
