A Direct Test of the Mixture of Distributions Hypothesis: Measuring the Daily Flow of Information

Matthew Richardson and Tom Smith

Journal of Financial and Quantitative Analysis, 1994, vol. 29, issue 1, 101-116

Abstract: This paper proposes and conducts direct tests of the mixture of distributions model for stock prices. By exploiting the model's bivariate conditional normality of price changes and trading volume, these restrictions can be tested under very weak assumptions regarding the daily flow of information to the market. As a technical byproduct, important parameters governing the distribution of this unobservable information flow are estimated.
