Information embedded in the trading volume of currency options

Return, Trading Volume, and Market Depth in Currency Futures Markets

We use a class of stochastic volatility models with multiple latent factors to investigate the joint dynamics of return, trading volume, and open interest (a proxy for market depth) in currency futures markets. In accordance with theory, the empirical evidence indicates that there is more than one latent factor affecting these three variables. However, the evidence is ambivalent on the choice b...

Extracting Information from Trading Volume

This paper shows how to extract information from equilibrium trading volume. The analysis is rst carried out in a market-clearing framework with symmetrically (and later normally) distributed demands, and is then extended to include market-making models. The conclusions of this paper hence apply to the majority of the models developed in the noisy rational expectations literature. If a random v...

Trading Volume, Information Asymmetry, and Timing Information

This paper investigates trading volume before scheduled and unscheduled corporate announcements to explore how traders respond to private information. I show that cumulative trading volume decreases by more than 15% prior to scheduled announcements. The decline in trading volume is largest when information asymmetry is high, while the opposite relation holds for volume after the announcement. I...

Timing Information, Information Asymmetry, and Trading Volume

Investigating various corporate announcements and abnormal return days, I observe that around 2% of daily trading volume decreases only before scheduled earnings announcements. This empirical pattern is robust across different specifications and periods. Also, proxies of ex ante information asymmetry are consistently related to the trading volume only before scheduled earnings announcements. Th...
