Screening Chinese Stocks by Prior-Day Leaders and Opening Gains

Summary

This stock-selection screen combines yesterday’s exchange leaderboard data, a ranking by reported capital flow intensity, and a limit on the current session’s opening gain. It first identifies stocks appearing on the prior day’s trading leaderboard, orders candidates by the amount of buying and selling activity, and keeps those whose 9:25 opening price is less than 6% above the previous close. The stated rationale is that strong capital activity may indicate continued interest, while capping the opening rise avoids selecting stocks that have already surged sharply before the session begins.

The post provides a qualitative rationale rather than backtest results, return data, or a precise definition of capital intensity. It cautions that the screen omits company fundamentals and longer-term performance, so high activity and prior leaderboard inclusion do not establish investment value or persistence. It suggests adding financial and industry factors and using longer histories, but supplies no tested refinements. The rule is best treated as a short-term candidate filter whose performance and execution would need separate evaluation.

Key ideas

• The screen starts with stocks listed on the previous day’s trading leaderboard.
• Candidates are ranked by the intensity of reported buying and selling amounts.
• The 9:25 opening gain must be below 6% relative to the previous close.
• The post offers a rationale but no measured evidence that these conditions predict returns.
• Fundamental factors and longer histories are suggested as possible additions.
