Screening Stocks by Limit-Ups, Afternoon Order Flow, and Position Increases

Summary

This post outlines a Chinese equity screen combining three signals: a position-increase share above 5%, net large-order inflow during the afternoon, and more than two limit-up sessions in the prior ten days. It interprets these as signs of recent capital inflow, buying interest, and strong market attention. A proposed expanded screen adds a market-cap floor, a price-to-earnings ceiling, a bounded daily return, and a closing price above the Bollinger middle band.

The post warns that recently popular stocks can be overpriced and vulnerable to sharp declines if conditions turn adverse. It suggests valuation and technical filters, but supplies no backtest or performance evidence. The included Python example is visibly incomplete, so it does not establish how to calculate or combine the signals reliably. The thresholds are presented as screening rules, not proof of future returns.

Key ideas

• The initial screen combines position increases, afternoon large-order net inflows, and repeated recent limit-up sessions.
• The expanded proposal adds market capitalization, valuation, daily return, and Bollinger-band conditions.
• The post warns that crowded, popular stocks may carry elevated downside risk.
• No performance tests are reported, and the sample Python code is incomplete.
