Screening Chinese Stocks by Fund Flow and Limit-Up Frequency

Summary

This stock screen ranks companies by a measure of capital strength, such as net inflows or trading value, and requires at least two limit-up sessions within a 500-day window. The article frames the screen as targeting stocks with strong buying interest and notable price gains, with a stated focus on 2021. It also suggests adding valuation and technical indicators to broaden the selection criteria.

The discussion is conceptual rather than a validated strategy report. It provides no portfolio construction rules, trade timing, transaction costs, benchmark comparison, or performance results. Its sample Python fragment is incomplete and does not implement the stated 500-day limit-up test or a clear capital-strength ranking, so it should not be treated as a reproducible backtest. The article itself notes that the narrow screen ignores company finances, industry conditions, and valuation, and may select expensive stocks.

Key ideas

• The screen ranks stocks by a capital-flow or trading-activity measure.
• It requires at least two limit-up sessions in a 500-day lookback.
• The article proposes adding valuation and technical measures as further filters.
• No performance evidence or complete reproducible implementation is supplied.
• Capital strength and price moves alone omit company and industry fundamentals.
