Stock Screening by Turnover, Recent Limit-Up, and Afternoon Fund Flows

Summary

This Chinese-language post describes an equity screen requiring turnover between 3% and 12%, at least one limit-up event within the preceding 25 days, and positive large-order net inflow in the afternoon. The proposed rationale is to find stocks with trading activity, recent market attention, and supportive short-term fund flows. The post includes indicator conditions and a Python-style example for selecting stocks.

The author cautions that this approach may overemphasize short-term flows and sentiment while neglecting broad market conditions and company fundamentals. Sector themes and overall market risk can also affect the selected names. Suggested refinements include adding financial measures and other market or technical signals, with adjustments based on each stock’s history and the prevailing market. No backtest or performance evidence is included, and the code example does not establish that the screen is profitable or robust.

Key ideas

• The screen combines turnover between 3% and 12%, a limit-up event in the prior 25 days, and positive afternoon large-order net inflow.
• The filters are intended to identify liquid stocks with recent attention and supportive fund flows.
• The approach may overemphasize short-term sentiment while overlooking fundamentals and broader market conditions.
• The post recommends additional financial and market signals, but reports no validation or performance results.
