A-Share Stock Screen for Recent Limit-Ups and Trading Activity

Summary

The proposed China A-share screen selects stocks using three short-term conditions: price amplitude above 1%, a high ranking in large-order net volume, and more than two limit-up days within ten days. The article frames these filters as a way to find actively traded stocks with recent upward momentum. It also suggests adding company fundamentals, industry conditions, broader market direction, and macroeconomic context before making investment decisions.

The article provides sample formula and Python snippets, but their implementation does not fully match the stated screen. The code uses turnover rate as a proxy for large-order net volume and counts positive daily price changes rather than actual limit-up closes. It also includes an amount threshold that is not part of the three headline conditions. The document warns that a short-term momentum screen may favor speculative or popular-theme stocks and does not account for business quality or longer-term prospects. It supplies no backtest results or evidence that the rules predict returns.

Key ideas

• The screen combines price amplitude, large-order net-volume ranking, and more than two recent limit-up days.
• The article presents the filters as a way to identify active stocks with short-term upward momentum.
• Its sample implementation substitutes turnover rate for large-order net volume and positive days for limit-up events.
• The code also imposes an amount threshold beyond the headline selection conditions.
• The author warns that short-term price strength may select speculative stocks and recommends considering fundamentals and market context.
