There are two competing hypotheses regarding the effects of increased financial disclosure. One states that increased disclosure leads to decreased information asymmetry and more efficient pricing resulting in reduced bid-ask spreads, volatility and illiquidity. The other says that increased disclosure places additional burdens on traders leading to increased transactions costs and volatility. This paper examines the effects of more-frequent reporting for the case of closed-end funds that voluntarily changed their net-asset-value reporting from weekly to daily beginning in 1998. Multivariate analyses indicate a decrease in asymmetric information following initiation of daily reporting as evidenced by lower spreads, greater transactions volume, reduced volatility and decreased illiquidity. We conclude that closed-end fund daily net-asset-value reporting provides an example of information disclosure that provides useful information to investors and reduces information asymmetry.
