Turnover-Based Screening for Shanghai-Listed Stocks

Summary

This stock-selection rule screens for equities whose current turnover rate is between 3% and 12%, whose ticker begins with 60, and whose previous-day actual turnover is described as between 3% and 28%. The post treats turnover as a rough indicator of trading activity and limits the universe to a particular group of Shanghai-listed shares. It notes that low-turnover emerging candidates could be excluded and that the screen may become less effective as market conditions change.

The article offers a Python example using stock listings and daily market data, but it does not report a backtest, returns, or other evidence that the filters predict performance. The example's turnover calculation and inequalities do not appear to implement the stated 3%–28% interval correctly, and the data fields used may not represent actual turnover as described. The written rule also recommends combining turnover with technical and fundamental measures, but gives no tested specification for doing so. Treat the code as illustrative and verify the universe and calculations before relying on its selections.

Key ideas

• The stated screen combines current turnover of 3%–12% with a previous-day turnover range of 3%–28%.
• It restricts the universe to stocks with codes beginning with 60.
• The article presents turnover as a proxy for trading activity, not as a standalone measure of stock quality.
• The sample calculation appears inconsistent with the written turnover interval and requires verification.
• No performance evidence is supplied, and the author notes that the screen omits other selection factors.
