A Chinese A-Share Screen for Recent Limit-Up Streaks
Summary
The proposed screen selects Shanghai-listed shares whose intraday range exceeds a threshold and that recorded three consecutive limit-up sessions through the previous trading day. The document presents the streak as a sign of market attention and strong buying interest, while the range condition targets shares with larger price movement. It also suggests ranking selected shares by turnover.
The article cautions that recent limit-ups alone do not establish investment value and that a stock may reverse after the streak, leaving a buyer exposed to losses. It recommends considering additional technical measures, such as volume or MACD, and company fundamentals and market outlook. The selection logic is described alongside sample formula and Python references, but no backtest results, holding period, execution rules, or risk-adjusted performance evidence are supplied. The screen is therefore a simple momentum-oriented candidate filter, not a complete strategy or evidence of persistent returns.
Key ideas
- The screen combines a minimum price-range condition with a three-session limit-up streak.
- It restricts candidates to shares with codes beginning with the specified Shanghai prefix.
- Turnover is suggested as a way to rank the resulting candidates.
- The article warns that a recent limit-up streak may not continue and can expose buyers to losses.
- It proposes adding technical and fundamental checks, but reports no strategy performance tests.
