Screening Shanghai-Listed Stocks by Turnover and Arc-Shaped Prices

Summary

This Chinese equity screen selects stocks with turnover between 3% and 12%, codes beginning with 60, and a price pattern described as arc-shaped. The article frames the turnover band as a liquidity-related filter and the code prefix as a way to constrain the eligible stock universe. Its sample Python approach checks a limited sequence of recent closing prices for a rough arc-like configuration, then shows how selected stocks could be ranked by market value.

The article argues that an arc-shaped pattern may indicate a relatively steady price path, but it presents no backtest or evidence that this shape predicts returns. It notes that the screen omits fundamentals and may miss worthwhile stocks whose charts do not fit the pattern. Suggested refinements include adding valuation measures and other technical indicators, with rules adjusted for industry and market conditions. The pattern test in the example is only a rough proxy, and its turnover condition is described but not implemented in the sample selection logic.

Key ideas

• The proposed screen combines a turnover range, a Shanghai-listed stock code prefix, and an arc-shaped price pattern.
• The sample code approximates the chart pattern using a short sequence of closing prices.
• The article suggests adding valuation data and technical indicators to broaden the analysis.
• No performance testing is reported, and the example does not implement every stated filter.
