Screening Chinese Stocks for Recent Limit-Ups and Afternoon Inflows

Summary

This stock-selection screen combines three conditions: a relative strength index below 65, positive large-order net inflow in the afternoon, and more than two limit-up days in the recent ten-day period. The article presents the setup as a way to find actively traded, speculative stocks whose momentum has not pushed the RSI above the chosen threshold. It also describes ranking eligible names by a heat measure and filtering by market capitalization and the Shanghai or Shenzhen exchanges.

The post includes formula and Python examples, but provides no backtest, returns, or risk-adjusted evidence. It warns that a rule set based on visible quantitative indicators may be overused, and suggests adding fundamentals and adjusting for sector and market conditions. The code’s handling of net flows and limit-up counts is not fully consistent with the stated screen, so implementation details should be checked before relying on it. The approach is a screening recipe, not evidence of a profitable strategy.

Key ideas

• The screen seeks stocks with RSI below 65, afternoon large-order inflows, and more than two recent limit-up days.
• It adds market-capitalization and exchange filters and ranks candidates by a heat measure.
• The stated rationale combines momentum, trading activity, and speculative interest.
• The article offers no performance results and cautions that visible indicator rules can be overused.
• Its examples may not exactly implement the written criteria, so their logic requires review.
