Screening Chinese A-Shares by Price Range and Limit-Up History

Summary

This Chinese A-share screening idea selects stocks whose daily high-low range exceeds 1% of the closing price and that have recorded at least two limit-up sessions within the previous 500 trading days. It excludes Beijing-listed A-shares. The stated rationale is that substantial price movement and repeated limit-ups may identify stocks that have attracted strong market attention and could have upside potential.

The article cautions that technical filters cannot predict future performance and that selected stocks may behave differently as market and economic conditions change. It suggests supplementing the screen with valuation, dividend, return-on-equity, or other technical measures, and adapting the stock universe to market conditions. The sample code is labeled as a reference, but does not provide backtest results or a complete validation process; its geographic exclusion and indicator calculations may also need implementation checks. The screen is therefore a candidate-generation rule, not evidence of a tested strategy or a complete trading plan.

Key ideas

• The screen requires a daily high-low range greater than 1% of the closing price.
• It looks for at least two limit-up events over the prior 500 trading days.
• The stated universe excludes Beijing A-shares.
• The proposed rationale links past volatility and limit-ups with market attention, not guaranteed future gains.
• The article recommends adding fundamental or other technical filters and adapting the stock pool to conditions.
