Chinese Stock Screening by Limit-Ups, Market Capitalization, and Position Changes

Summary

This Chinese stock-screening post combines three filters: more than two limit-up sessions within ten days, a circulating market value of 5–10 billion yuan, and a daily position-increase ratio above 5%. It describes the filters as proxies for buying interest, moderate company size, and strong recent price action. The document also discusses possible additions such as valuation measures and a stop-loss rule.

The post warns that capital flows are hard to predict, smaller stocks may be less liquid, and repeated limit-ups can signal overheating and a possible pullback. It later presents a different proposed screen with a 50–100 billion yuan market-cap range, valuation thresholds, a recent-price-stability condition, and the same limit-up filter. The sample Python snippet does not implement all the stated conditions consistently, and the post provides no backtest or performance evidence. The screen is therefore a set of hypotheses rather than demonstrated investment guidance.

Key ideas

• The initial screen combines recent limit-up frequency, circulating market capitalization, and reported position increases.
• These filters aim to capture recent strength and buying interest in moderately sized stocks.
• The document identifies liquidity constraints and short-term overheating as risks.
• It proposes adding valuation and risk controls but provides no performance test of the revised screen.
