Chinese Stock Momentum Screen Using Weekly Trend and Recent Limit-Ups

Summary

This Chinese stock-selection proposal combines three signals: today’s position-increase share above 5%, a weekly five-period moving average crossing above the ten-period average, and more than two limit-up sessions in the last ten days. The accompanying rationale interprets the position-increase measure as evidence of buying interest, the moving-average crossover as an upward trend signal, and repeated limit-ups as a sign of market attention. The proposed final screen adds a market-cap threshold, selected industries, and a low price-to-earnings ratio.

The document gives no backtest or measured returns, and it does not define the position-increase metric or establish that its signals predict future performance. It warns that each condition can identify stocks after sharp short-term gains, exposing buyers to reversal risk. Its sample Python material is incomplete and does not demonstrate the full stated selection logic, so it should not be treated as a validated implementation. The added fundamental and industry filters are suggestions, not tested evidence of improved accuracy or stability.

Key ideas

• The screen combines a position-increase share above 5%, a weekly five-period moving-average crossover, and more than two limit-up days within ten days.
• The final proposed rules add market capitalization, industry, and valuation filters.
• The source interprets the signals as evidence of buying interest, trend strength, and market attention.
• It warns that the signals may select stocks after substantial short-term rises, creating reversal risk.
• No performance evidence is provided, and the sample code does not implement the complete stated strategy.
