Screening Chinese Equities by Price Range, Daily Range, and Trading Interest

Summary

This post presents a proposed stock screen based on daily price amplitude above one percent, a share price of 18.5 yuan, and ranking by individual-stock popularity. It frames amplitude and price as selection conditions and popularity as an ordering measure for short-term trading. It also notes that the screen ignores company finances, management, and industry prospects, and recommends supplementing it with broader fundamental and technical criteria.

The examples are internally inconsistent. The prose specifies the amplitude, exact price, and popularity ranking, but the Python sample instead applies moving-average and positive-PE filters and sorts selected stocks by trading volume. The document provides no evidence that either version produces favorable returns, and it does not define a robust way to measure popularity. Its risk discussion recognizes that popularity can be distorted and that a screen omitting company fundamentals can select unsuitable stocks. The examples should therefore be treated as rough illustrations rather than a tested strategy specification.

Key ideas

• The stated screen selects stocks with daily amplitude above one percent and a price of 18.5 yuan, then ranks them by popularity.
• The post positions the approach for short-term trading but provides no performance evidence.
• Its Python example differs from the written rules, using moving-average and PE filters and sorting by volume.
• Popularity can be manipulated, and the screen omits financial, management, and industry analysis.
• Additional fundamental and technical criteria are suggested to broaden the selection process.
