Screening Recent IPOs for Turnover and Reversal Patterns

Summary

This article describes a Chinese stock screen combining turnover of 3% to 12%, a 2021 listing year, and a reversal pattern identified by the Chinese term “fanbao.” It provides sample indicator and Python-style snippets, including a three-session average turnover filter and a name-based search for the reversal label. The examples do not consistently implement the stated listing-year condition, and the article’s discussion also refers to float value without clearly including it in the final rule.

The piece offers no performance results or validation. It characterizes the method as a simple screen and cautions that static filters may not adapt to changing markets or capture the intended pattern reliably. It recommends considering valuation measures and adapting criteria across industries and market conditions. The snippets should therefore be treated as illustrative screening logic whose data fields and pattern definitions require verification before use.

Key ideas

• The stated screen combines a 2021 listing year, a reversal pattern, and turnover in a specified range.
• The sample formulas use recent average turnover and a text-based pattern label, but do not consistently encode every stated condition.
• The document reports no backtest or evidence that the filters predict returns.
• The author identifies static criteria and incomplete market context as limitations and suggests additional valuation or market-specific filters.
