A-Share Stock Screen Using Price Range and Prior Limit-Up Status

Summary

This stock-selection idea screens Chinese A-shares by requiring a daily high-low range above a threshold, excluding stocks that hit the upper price limit on the previous day, and omitting Beijing-listed shares. The stated rationale is that a larger range may identify more active opportunities, while excluding recent limit-up stocks may avoid unstable rapid rises. The article also suggests combining the screen with fundamental, technical, macroeconomic, and industry analysis.

The accompanying implementation outline adds extra conditions, including price-change and data-history checks, so it does not exactly match the verbal rules. The article offers no backtest, return series, or evidence supporting its rationale. It acknowledges that volatility can increase risk and that ignoring other factors may hurt the payoff profile. The selection criteria should therefore be treated as a preliminary screen, with the discrepancies and market-specific assumptions checked before any evaluation.

Key ideas

• The proposed screen selects A-shares with a daily high-low range above a stated threshold.
• It excludes shares that reached the upper price limit the prior day and omits Beijing-listed stocks.
• The article suggests adding fundamental, technical, macroeconomic, and industry information for further selection.
• The implementation outline contains additional conditions beyond the stated screen, and no performance evidence is given.
