A-Share Screen Using Turnover, IPO Year, and Opening Gap

Summary

This Chinese equity screening note combines a turnover range of 3% to 12%, an IPO year of 2021, and an opening price between 2% below and 5% above the previous close. It presents turnover as a liquidity filter and the opening move as a rough way to reflect market attention and money flows. The examples also bring in market capitalization and trading volume conditions, although those are not part of the stated final screening rule.

The post supplies sample formula and Python logic, but no results, historical test, or evidence that the conditions improve returns. It cautions that opening changes may not capture a stock’s true prospects, and that the screen omits technical and valuation analysis. There are inconsistencies between the described rule and the example code: the code uses an IPO year threshold of 2021 or later, rather than exactly 2021, and applies extra volume and market-cap filters. The note suggests adding technical and fundamental measures, but does not specify or validate a combined strategy.

Key ideas

• The stated screen uses turnover of 3% to 12%, a 2021 listing year, and an opening move from 2% down to 5% up.
• The code example adds market-capitalization and volume conditions beyond the stated rule.
• The example code uses an IPO year threshold of 2021 or later, which differs from the stated 2021 listing year.
• The post offers no backtest or return evidence and identifies gaps in valuation and technical analysis.
