Chinese Stock Screen Using Range, Institutional Flows, and Market Capitalization

Summary

This Chinese-language post describes an equity screen that selects stocks with a daily high-low range greater than one, positive institutional net flow, and circulating market capitalization above 10 billion yuan. Its rationale is to combine elevated price movement, evidence of institutional buying, and a minimum company size. The examples express the filters in indicator-style and Python-like form; the flow condition sums net amounts over five observations, and the resulting candidates are sorted by turnover.

The post notes that the screen may expose investors to liquidity and market-direction risks, and that range and flow signals do not capture fundamentals or long-term prospects. It suggests adding fundamental criteria and applying risk controls, but provides no tested refinement or performance data. The code is presented as an example needing adjustment, and the data calls, units, and timing assumptions are not validated in the document. The final proposed screen is broader than the three coded filters, since it also mentions fundamental assessment without specifying a concrete rule.

Key ideas

• The screen combines a high-low range threshold, positive institutional net flows, and a minimum circulating market value.
• The sample flow filter aggregates net amounts across five observations.
• Selected stocks are ordered by turnover in the Python example.
• The post flags liquidity, market-direction, and missing-fundamentals risks.
• It offers no backtest results, and its code is described as an adaptable example.
