Screening Chinese Stocks by Range, Recent Limit-Ups, and Float Value
Summary
This proposed Chinese equity screen selects stocks whose daily high-low range exceeds 1%, that had at least one limit-up day in the preceding 25 trading days, and whose circulating market value exceeds 10 billion yuan. The article interprets the range condition as a sign of elevated volatility, a recent limit-up as evidence of market interest, and the market-value threshold as a size filter. The selected stocks are placed in a candidate pool; the document does not specify portfolio weights or when to buy or sell them.
The article gives sample indicator logic and Python-style selection code, but reports no backtest results, returns, or risk statistics. It cautions that historical selection criteria may not predict future performance and that neither limit-ups nor company size guarantees subsequent gains or business quality. It suggests adding valuation, growth, and financial measures, and screening by industry or size to address concentration and individual-stock risk. The criteria are a screening hypothesis, not demonstrated evidence of an investable edge.
Key ideas
- The screen combines a daily range threshold, a recent limit-up event, and a circulating market-value floor.
- A limit-up must have occurred at least once in the prior 25 trading days.
- Qualifying stocks enter a candidate pool, but the document gives no portfolio construction rules.
- The article warns that historical conditions do not establish future price performance.
- It recommends adding company fundamentals and grouping screens to address concentration risk.
