Selecting Stocks by Volatility, Recent 10% Gains, and Limit-Ups

Summary

This Chinese-language post describes a stock screen combining three signals: a trading range greater than the stated threshold, at least one daily gain of 10% or more during the prior 25 sessions, and a limit-up event in the preceding 25 days. It frames the screen as a way to find volatile stocks with recent momentum and market attention. It also includes example indicator logic and a Python sketch, though the implementations do not clearly match every stated condition.

The post warns that recent strength and popularity can leave shares overvalued, that sentiment can shift quickly, and that a short-term screen may overlook fundamentals and long-run performance. It suggests adding fundamental checks, favoring stronger companies within hot sectors, and combining multiple measures. No backtest results, performance evidence, or complete risk controls are provided, so the screen should be treated as a hypothesis rather than a validated strategy.

Key ideas

• The screen combines volatility, a recent large daily gain, and a recent limit-up event.
• The stated lookback for the gain and limit-up conditions is 25 trading days.
• The author associates the signals with market attention and short-term momentum.
• Recent price strength can increase overvaluation and sentiment risk.
• The post provides no performance evidence and recommends adding fundamental and other screening criteria.
