A-Share Screen Combining Turnover, Prior-Day Leaderboard, and Daily Gains

Summary

This proposed mainland China stock screen combines turnover between 3% and 12%, appearance on the prior day’s trading leaderboard, and a gain greater than 1% for a main-board stock on the current day. It aims to identify actively traded names that have recently drawn market attention and are rising. The article gives a formula-style condition and a data example, though the example uses price-limit fields in a way that does not clearly match the stated daily return condition.

The author notes that the screen omits company fundamentals and that a one-day rise may not persist. Suggested additions include earnings and valuation measures, along with technical indicators. The document offers no backtest results, return statistics, or evidence that leaderboard appearance combined with turnover predicts continued gains; the filters are therefore an unvalidated screening hypothesis.

Key ideas

• The proposed screen combines turnover from 3% to 12%, a prior-day leaderboard appearance, and a current main-board gain above 1%.
• The approach uses recent attention and trading activity as selection criteria.
• The article warns that it excludes fundamental analysis and that a single-day gain may not persist.
• No performance testing is reported, and the sample formula does not clearly correspond to the stated daily-gain filter.
