This paper is a continuation of Ishitani and Kato (2015), in which we derived a continuous-time value function corresponding to an optimal execution problem with uncertain market impact as the limit of a discrete-time value function. Here, we investigate some properties of the derived value function. In particular, we show that the function is continuous and has the semigroup property, which is strongly related to the Hamilton-Jacobi-Bellman quasi-variational inequality. Moreover, we show that… Expand
An Optimal Execution Problem with S-Shaped Market Impact Functions
In this study, we extend the optimal execution problem with convex market impact function studied in Kato (2014) to the case where the market impact function is S-shaped, that is, concave on $[0,Expand

Mathematical Formulation of an Optimal Execution Problem with Uncertain Market Impact
TLDR
A discrete-time model as a value function for optimal execution is constructed and it is found that the continuous-time value function is characterized by a stochastic control problem with a Levy process. Expand

Large investor trading impacts on volatility
We begin with this paper a series devoted to a tentative model for the influence of hedging on the dynamics of an asset. We study here the case of a “large” investor and solve two problems in theExpand

TLDR
It is found that right-continuity at the time origin is associated with the strength of market impact for large sales; otherwise the value function is continuous. Expand

VWAP Execution as an Optimal Strategy
TLDR
This study explicitly introduces a trading volume process into the Almgren-Chriss model, which is a standard model for optimal execution and shows that the VWAP strategy is the optimal execution strategy for a risk-neutral trader. Expand
Optimal Execution of a VWAP Order: A Stochastic Control Approach
We consider the optimal liquidation of a position of stock (long or short) where trading has a temporary market impact on the price. The aim is to minimize both the mean and variance of the orderExpand
Optimal Execution with Uncertain Order Fills in Almgren-Chriss Framework
The classical price impact model of Almgren and Chriss is extended to incorporate the uncertainty of order fills. The extended model can be recast as alternatives to uncertain impact models andExpand
An Optimal Execution Problem with a Geometric Ornstein-Uhlenbeck Price Process
We study an optimal execution problem in the presence of market impact where the security price follows a geometric Ornstein-Uhlenbeck process, which implies the mean-reverting property, and showExpand
