Tail Liquidity Premium Factor

Research Factor Name
Fund Quarterly Consensus Surprise Momentum
Hypothesis
During periods of market stress, small-cap or low-liquidity stocks often experience excessive discounting due to concentrated selling by investors, yet they tend to exhibit stronger subsequent rebounds compared to large-cap stocks—manifesting a "tail liquidity premium." This phenomenon stems from institutional aversion to liquidity risk and retail-driven irrational trading under extreme sentiment, creating short-term mispricing that offers opportunities for contrarian strategies.
Implementation
Using daily trading data from the past 20 days, select the bottom 10% of stocks by turnover ratio across the market. Compute the volatility of their excess returns relative to industry averages. The final factor score is the product of this volatility and the magnitude of recent price drawdown, designed to identify oversold tail assets with rebound potential.
A fund manager's skill is reflected not only in the persistence of past performance but, more importantly, in the ability to anticipate and position ahead of changes in corporate earnings. When a fund's portfolio of top holdings exhibits a collective upward revision in future earnings estimates (e.g., next-quarter consensus EPS) that is significantly stronger than the market average following the quarterly report disclosure, it signals that the manager's stock selection is receiving immediate validation from professional sell-side analysts. This "consensus surprise," derived from institutional judgment, contains positive information not yet fully priced by the market. The gradual digestion of this information and subsequent capital inflows create a momentum effect, allowing funds with this characteristic to continue outperforming in the subsequent period.
