The purpose of this paper is to investigate the effects of information asymmetry (between the realized return and the expected return) on market timing in the mutual fund industry.
For the purpose, the authors use a panel of 1,488 active open-end mutual funds for the period 2004-2013. The authors use fund-specific time-dynamic betas. The information asymmetry is measured as the standard deviation of idiosyncratic risk. The data set is decomposed into five market fundamentals in order to emphasis the policy implications of the findings with respect to: equity, fixed income, allocation, alternative, and tax-preferred mutual funds. The empirical evidence is based on endogeneity-robust difference and system generalized method of moments.
The following findings are established. First, the information asymmetry broadly follows the same trend as volatility, with a higher sensitivity to market risk exposure. Second, fund managers tend to raise (cutback) their risk exposure in time of high (low) market liquidity. Third, there is evidence of convergence in equity funds. The authors may, therefore, infer that equity funds with lower market risk exposure are catching-up with their counterparts with higher exposure to fluctuation in market conditions.
The paper complements the sparse literature on market timing in the mutual fund industry with time-dynamic betas, information asymmetry and an endogeneity-robust empirical approach.
