Stock Momentum Screen Using Turnover, Moving Averages, and Limit-Up History

Summary

This document describes a Chinese stock screen that ranks shares by volume ratio, retains those with a 20-day moving average above the 120-day average, and requires at least two limit-up sessions within the prior 500 days. The accompanying explanation treats volume ratio as a proxy for market attention, the moving-average relationship as a short-versus-long trend filter, and prior limit-ups as evidence of past activity. The stated selection logic is incomplete: the final section cuts off before restating all conditions.

The article notes that volume ratio does not directly establish net fund inflows, moving averages may miss broader long-term conditions, and limit-up history alone may not identify the most followed stocks. It suggests adding flow, turnover, valuation, trading-volume, and industry information. No implementation details sufficient to resolve these issues or backtest results are supplied. The historical limit-up count and trend filters therefore serve as screening heuristics, not demonstrated evidence of future returns.

Key ideas

• The screen ranks stocks by volume ratio and filters for a 20-day average above the 120-day average.
• It also requires at least two limit-up sessions over the preceding 500 days.
• The document interprets the conditions as proxies for attention, trend, and past activity.
• It warns that volume ratio does not directly measure net inflows and that the filters may miss broader context.
• The final selection description is truncated, and the article gives no backtest evidence.
