Decomposing returns into market and stock speci?c components is commonpractice and forms the basis of popular asset pricing models. But what aboutvolume ? Can volume be decomposed in the same way as returns ? Lo andWang (2000), in a recent paper, suggest such a decomposition. Our paperis in this...

In this paper, we present a new methodology for modeling intraday volume which allows fora significant reduction in the Volume Weighted Average Price (VWAP) on orders risk. Theresults are obtained for the all stocks included in the CAC40 index at the beginning ofSeptember 2004. The idea of...

In a new environment where liquidity providers as well as liquidity consumers act strategically, understanding how liquidity flows and dries-up is key. In this paper, we propose a dynamic extension of the seminal model of Tauchen and Pitts (1983)' Mixture of Distributions Hypothesis (MDH) that...

We propose a new bivariate nonnegative integer-autoregressive (BINAR) model for count process data. We first generalize the existing BINAR(1) model by allowing for dependence between different thinning operators. The extended family allows for intuitive interpretation, as well as tractable...

In this paper, we present a new methodology for modelling intraday volume, which allows for a reduction of the execution risk in VWAP (Volume Weighted Average Price) orders. The results are obtained for all the stocks included in the CAC40 index at the beginning of September 2004. The idea of...

This paper analyses the purchase and redemption behaviour of mutual fund investors and its implications on fund liquidity risk. We collect a novel set of proprietary data which contains a large number of French investors holding funds with various degrees of asset liquidity. We build a...

Financial markets are today so interconnected that they are fragile to contagion. Massive investment funds with very short horizons in -and out- flows can generate contagion effects between markets. Since 2010, investors are willing to get a liquid exposure to the EM sovereign debt. As a...

This paper proposes a new dynamic approach to modelling intra-day trading volume based on factor models. It assumes that intra-day volume can be decomposed into two parts each predicted using separate time-series models. By enabling more accurate prediction of intra-day volume, this methodology...
