This paper examines the patterns of trading behaviour, in the period surrounding monetary policy announcements. Utilizing a high-frequency data-set, with broker identifiers enabling classification of trades executed through institutional and retail brokers, I investigate all trades submitted on...

When private information is observed by ambiguity averse investors, asset prices may be informationally inefficient in rational expectations equilibrium. This inefficiency implies lower asset prices as uninformed investors require a premium to hold assets and higher return volatility relative to...

An alternative derivation of the yield curve based on entropy or the loss of information as it is communicated through time is introduced. Given this focus on entropy growth in communication the Shannon entropy will be utilized. Additionally, Shannon entropy's close relationship to the...

The co-movements are strongly related to systematic risk factors and to the theoretical debt-to-equity hedge ratio. I document that hedging and...

This paper introduces a novel hypothesis in the context of share buybacks, proposing the existence of a "Free Lunch" phenomenon associated with the use of specific execution products. The hypothesis posits that these products can generate consistently positive fees, offering a consistent return...

This study examines the effect of option volume relative to stock volume (O/S) on market response to earnings surprises. The market reaction per unit of earnings surprise is lower for firms that have high O/S prior to earnings announcement than for firms with low O/S prior to earnings...

Stock market makers are afraid that informed insiders will take advantage of them in trade. To protect themselves, they may increase the bid-offer spread to include a fee for the adverse selection risk . If set correctly, market makers will share in profits from others trading on private...

We investigate the specification and power of intraday event study test statistics. Both the mean and market models generate well-specified return results for one- to thirty- minute intervals. Moreover, they detect return shocks equivalent to one spread in one- and five-minute interval data and...

This paper investigates the robustness of post-earnings-announcement-drift (PEAD) on a price signal perspective, unlike the traditional literature that focuses on fundamental signal. The studied period is 2003-2015, for four main US indices. The results suggest that some economic agents are too...
