Screening 2021 IPOs by Turnover and Circulating Market Value

Summary

This document proposes a Chinese equity screen requiring turnover between 3% and 12%, a 2021 listing year, and circulating market value above 10 billion yuan. It describes the screen as a way to find relatively large, active stocks that might be undervalued, but provides no evidence that these conditions identify mispricing or lead to profitable trades. The article also suggests adding fundamental and technical measures, such as valuation ratios or price indicators, and testing across markets and time periods.

The implementation examples are not fully consistent with the stated rule. The formula includes additional conditions, while the Python example uses different market-value and turnover comparisons and adds trading-data filters. The source does not reconcile these differences or report a backtest, so the examples should not be treated as a validated, exact implementation of one strategy. It also acknowledges that the screen omits other fundamental and technical risks and that results may depend on market conditions. The proposed filters are therefore a starting point for research rather than a demonstrated investment method.

Key ideas

• The stated screen selects stocks listed in 2021 with turnover from 3% to 12% and circulating market value above 10 billion yuan.
• The article gives no performance evidence that these filters identify undervalued stocks.
• The formula and Python example contain different thresholds and additional conditions.
• The author suggests adding fundamental or technical filters and testing across markets and periods.
• Market conditions and omitted company characteristics may materially affect screening results.
