Screening Shanghai-Listed Stocks with Turnover and Moving-Average Alignment

Summary

The document describes a Chinese equity screening idea: retain stocks whose codes begin with 60, whose turnover rate falls between 3% and 12%, and whose three technical indicators show a bullish crossover. The accompanying explanation frames these filters as a way to find stocks with upward short-term trends and stronger buying interest. A code sketch checks the code prefix and compares 5-, 20-, and 60-period moving averages in ascending order, although it does not implement the stated turnover filter or explicitly calculate crossover events.

The author warns that combining many indicators can overfit historical data and that changing market conditions can make signals ineffective. The suggested improvement is to use a smaller set of relatively stable, nonredundant indicators. No backtest results or evidence of profitability are provided, and the code example’s data date and implementation leave important strategy details unresolved.

Key ideas

• The proposed screen combines a Shanghai stock code prefix, a turnover range, and three simultaneous bullish indicator signals.
• The code sketch approximates bullish alignment with the 5-period average above the 20-period average and the 20-period average above the 60-period average.
• The example code does not implement the stated turnover constraint or establish actual crossover timing.
• The document identifies overfitting and changing market conditions as risks and recommends limiting redundant indicators.
