Calibration of optimal execution of financial transactions in the presence of transient market impact
Calibration financial transactions market
2012/9/14
Trading large volumes of a nancial asset in order driven markets requires the use of algorithmic execution dividing the volume in many transactions in order to minimize costs due to market impact. A ...
Computing Quantiles in Regime-Switching Jump-Diffusions with Application to Optimal Risk Management: a Fourier Transform Approach
regime switching jump-diffusion models Value at Risk risk management Fourier transform methods.
2012/9/14
In this paper we consider the problem of calculating the quantiles of a risky position,the dynamic of which is described as a continuous time regime-switching jump-diffusion, by using Fourier Transfor...
Large tick assets: implicit spread and optimal tick size
Microstructure of nancial markets high frequency data large tick assets implicit spread market making limit orders market orders optimal tick size.
2012/9/14
In this work, we bring to light a quantity, referred to as implicit spread, playing the role of spread for large tick assets, for which the e ective spread is almost always equal to one tick. The rele...
On the non-stationarity of financial time series: impact on optimal portfolio selection
non-stationarity of financial time series impact optimal portfolio selection Statistical Finance
2012/6/2
We investigate the possible drawbacks of employing the standard Pearson estimator to measure correlation coefficients between financial stocks in the presence of non-stationary behavior, and we provid...
Optimal simulation schemes for Levy driven stochastic differential equations
Levy-driven stochastic differential equations high order discretization schemes weak approximation regular variation
2012/4/28
We consider a general class of high order weak approximation schemes for stochastic differential equations driven by L\'evy processes with infinite activity. These schemes combine a compound Poisson a...
Optimal split of orders across liquidity pools: a stochastic algorithm approach
Asset allocation Stochastic Lagrangian algorithm reinforcement principle monotone dynamic system
2010/11/2
Evolutions of the trading landscape lead to the capability to exchange the same financial
instrument on different venues. Because of liquidity issues, the trading firms split large orders across seve...

Variance Optimal Hedging for continuous time processes with independent increments and applications.
On the rates of convergence of simulation based optimization algorithms for optimal stopping problems
optimal stopping simulation based algorithms entropy with bracketing increments of empirical processes
2010/11/2
In this paper we study simulation based optimization algorithms for solving discrete time optimal stopping problems. This type of algorithms became popular among practioneers working in the area of qu...
On Azema-Yor processes, their optimal properties and the Bachelier-Drawdown equation
optimal properties Bachelier-Drawdown equation
2010/10/29
We study the class of Az´ema–Yor processes defined from a general semimartingale with a continuous running supremum process. We show that they arise as unique strong solutions of the Bachelier s...
Regularity of the Optimal Stopping Problem for Levy Processes with Non-Degenerate Diffusions
Regularity Levy Processes Non-Degenerate Diffusions
2010/10/29
The value function of an optimal stopping problem for a process with L´evy jumps is known to be a generalized solution of a variational inequality. Assuming the diffusion component of the proces...
Optimal systems of subalgebras for a nonlinear Black-Scholes equation
Black - Scholes model nonlinearity optimal system
2010/10/29
The main object of our study is a four dimensional Lie algebra which describes the symmetry properties of a nonlinear Black-Scholes model. This model implements a feedback effect which is typical for ...
Optimal execution of Portfolio transactions with geometric price process
Optimal execution Portfolio geometric price process
2010/11/2
In this paper we derive the Markowitz-optimal, deterministic-execution trajectory for a trader who wishes to buy or sell a large position of a share which evolves as a geometric Brownian
motion in co...
