Report on Accelerated Turnover Factor Analysis

This study focuses on enhancing liquidity-based alpha factors by examining dynamic changes in turnover rates, contrasting with traditional static approaches. The key findings highlight the effectiveness of embedding individual stock timing signals, such as volume increase on rising prices, to create robust predictive indicators. The accelerated turnover factor demonstrates strong performance across various dimensions, including individual stocks and industries, with applications in index enhancement that favor small-cap stocks. Overall, while the method shows promise with high information coefficients and excess returns, historical tests emphasize the need for caution as market styles may shift.

Notable points include:

• Static liquidity factors predict returns well, but dynamic turnover changes provide additional alpha opportunities.
• The volume increase on price rise signal yields top-tier performance with RankIC mean of -105% and annualized ICIR of -429%.
• Interactions across stock, industry, and market levels are crucial, with negative signals sometimes expected but mitigated by cross-level adjustments.
• Strong results in index enhancements (e.g., 108% annual excess for Chinese 1000 index) validate the method.
• Caveats: Factors may not retain effectiveness due to evolving market conditions.

Risk warnings: While quantitative results are promising, past performance does not ensure future gains.
