Chinese Stock Screen Using Turnover, Prior-Day Leaderboard, and Auction Value

Summary

This short-term Chinese equity screen selects stocks with turnover between 3% and 12% that appeared on the prior day’s trading leaderboard, then ranks them by the current day’s auction amount and keeps the top five. The article presents the conditions as a way to combine trading activity, recent market attention, and pre-open participation. It includes a simple filtering example based on turnover and leaderboard status, followed by a descending sort on auction amount.

The document offers a rule specification and code illustration, but no historical test, return data, or evidence that leaderboard appearances or auction value forecast subsequent performance. It warns that the small set of short-term signals may overfit and leave out fundamentals and industry context. The text also characterizes leaderboard inclusion as institutional attention, but provides no method for verifying that interpretation or assessing how robust the screen is across market conditions.

Key ideas

• The screen restricts turnover to the 3%–12% range and requires a prior-day leaderboard appearance.
• Candidates are ranked by current-day auction amount, with the top five selected.
• The article frames these filters as measures of liquidity, market attention, and pre-open activity.
• No backtest or return evidence is supplied.
• The document cautions that a few short-term filters can overfit and ignore fundamentals and industry factors.
