Screening Shanghai-Listed Stocks by Turnover and Institutional Holdings

Summary

This post describes a Chinese equity screen that selects stocks with turnover between 3% and 12%, stock codes beginning with 60, and a positive recent change in institutional ownership. Its stated rationale is that rising institutional holdings may indicate investor interest, while the turnover band narrows the candidate set. The sample Python approach estimates changes using reported top shareholder holding ratios over a date range.

The author warns that the screen omits company fundamentals and other technical measures, and that institutional holdings can reflect individual institutions’ preferences rather than reliable forward-looking information. The post recommends combining ownership data with financial and technical factors. It provides no backtest, return evidence, or definition of how recent ownership changes should be timed in live use, so the signal’s usefulness and stability are not established.

Key ideas

• The screen restricts candidates to stocks with codes beginning with 60 and turnover in a specified band.
• A positive change in reported major-holder ratios is used as a proxy for institutional buying interest.
• The post cautions that ownership changes may be misleading and that other technical and fundamental factors are missing.
• The sample method measures changes in reported holder ratios, but does not establish a live trading rule or signal timing.
• No backtest or evidence of investment performance is presented.
