Turnover, Float Size, and KDJ Crossover Stock Screening

Summary

This Chinese stock-screening example combines a turnover filter, a limit on circulating shares, a circulating-market-cap condition in its final rule, and a newly formed KDJ crossover. The formula and Python reference identify the crossover by comparing prior and current KDJ values, with an additional condition on the J and K lines. The article characterizes the approach as suited to short-term trading, but provides no backtest, trade examples, or evidence that the rules capture profitable moves.

The description cautions that the screen omits company fundamentals and does not establish whether prices will continue upward after a crossover. It suggests adding other technical or fundamental measures and setting a stop level. The specifications are inconsistent: the opening rule gives turnover of 3% to 12% and a share-count ceiling, while the final rule adds a market-cap threshold and omits the lower turnover bound. The accompanying code also presents further filters as optional examples. Those differences need resolution before implementation.

Key ideas

• The screen combines turnover, circulating share count, market capitalization in its final rule, and KDJ crossover conditions.
• The article frames the method as short-term but supplies no performance evidence.
• A KDJ crossover alone does not establish that an upward move will continue.
• The opening and final screening rules differ on turnover and market-cap conditions.
• Additional indicators, fundamentals, and a stop level are suggested as possible extensions.
