Screening Stocks with Moving Average, Limit-Up, and Volume Filters

Summary

This Chinese equity screening idea combines three conditions: the 20-day moving average must exceed the 120-day moving average, the stock must have recorded at least two limit-up sessions in the prior 500 days, and its volume ratio must rank among the top 500 stocks. The post frames the moving average comparison as a trend filter, past limit-up activity as a sign of strong price moves, and relative trading activity as a measure of market attention. It suggests combining the signals with technical and fundamental analysis.

The article gives only a partial Python sketch and no complete selection workflow, portfolio construction rules, backtest, or performance evidence. Its explanation also treats high attention and earlier price surges as possible indicators of upside, not proven predictors. The author cautions that the filters are simple and may be affected by sentiment and capital flows, which can increase price volatility. The described signals therefore define a candidate screen, not a tested standalone trading strategy.

Key ideas

• The screen requires the 20-day moving average to be above the 120-day moving average.
• It also requires at least two limit-up sessions in the previous 500 days.
• The volume ratio is used to select stocks ranked among the top 500.
• The article provides no backtest or evidence that these conditions predict future returns.
• The author warns that simple signals may be affected by sentiment and capital flows.
