Chinese Stock Screen for Volatility, Institutional Flow, and Recent Limit-Ups

Summary

This stock-screening idea combines three conditions: amplitude above 1, a change in an institutional trading-volume measure, and at least one limit-up event within the prior month. The accompanying explanation treats volatility as a sign of active trading, the institutional measure as a possible signal of institutional interest, and a recent limit-up as evidence of upward price strength. It presents the combination as a way to identify candidates for further consideration, rather than providing entry, exit, or position-sizing rules.

The post warns that these filters omit company fundamentals and valuation, rely heavily on technical or historical data, and may miss other attractive stocks. It suggests adding valuation measures and industry or leading-company analysis. The post gives indicator expressions and an illustrative Python outline, but no backtest, performance results, precise definitions for all signals, or evidence that the screen predicts future returns. The code and signal descriptions should therefore be treated as a rough screening proposal, not a validated strategy.

Key ideas

• The screen requires amplitude above 1, a nonzero change in an institutional volume measure, and a limit-up event within the past month.
• The post interprets volatility, institutional activity, and recent price strength as complementary stock-selection clues.
• It recommends adding valuation and industry analysis to address gaps in the three-condition screen.
• No backtest or measured returns are supplied, and the signal definitions are not fully established in the post.
