Chinese Stock Screen for Volatility, Afternoon Inflows, and Three Limit-Ups

Summary

This Chinese equity screen combines three short-term signals: daily amplitude above 1%, net inflow from large orders in the afternoon, and a three-session limit-up streak ending the previous day. It interprets amplitude as evidence of price movement, afternoon order flow as a sign of buying interest, and repeated limit-ups as a marker of market attention. The article also gives indicator formulas and a Python example intended to identify candidates.

The method is speculative and focused on recent price action. The article warns that volatility and short-term popularity do not establish long-term business quality, and that market conditions, fundamentals, and investor behavior can all affect outcomes. It suggests adding financial measures, longer-horizon relative performance or valuation measures, and industry or operating factors. No backtest results or performance evidence are provided, and the sample code’s conditions should not be treated as a validated implementation of the stated screen.

Key ideas

• The screen seeks stocks with amplitude above 1%, afternoon large-order net inflows, and three consecutive limit-up sessions ending the previous day.
• It combines price volatility, order-flow information, and recent momentum as indicators of short-term interest.
• The article describes the approach as speculative and cautions that it omits longer-term fundamental analysis.
• Suggested refinements include financial, valuation, relative-performance, industry, and business measures.
• The document provides formulas and sample code but no evidence of tested performance.
