Brooklyn Quant Experience Lecture Series: Marina Di Ciacinto

Brooklyn Quant Experience Lecture Series, NYU TandonDear All,

You are cordially invited to the Brooklyn Quant Experience Lecture Series (BQE) on Thursday, February 27th at 5 p.m.* in the NYU Tandon MakerSpace at 6 MetroTech Center, 1st Floor in Downtown Brooklyn.

*Please note the time change for this week’s event. The BQE Lecture Series is normally held at 6 p.m. 

Dr. Marina Di Ciacinto will present a talk on the following topic:

Title:

Dynamic Optimal Execution with Inventory Cost

Abstract

We consider the problem of optimal liquidation of a position in a risky security quoted in a financial market, where price evolution is risky and trades have an impact on price as well as uncertainty in filling orders. We generalize the Almgren and Chriss model by adding extra features that model the market maker’s impact on the price by an Ornstein-Uhlenbeck process. During execution, market makers are assumed to mean revert their inventories to a preassigned capacity. The market is populated by a multiplicity of market makers with heterogeneous mean reversion time-scales. The stochastic control problem can be solved by dynamic programming approach. We first solve analytically the related HJB equation finding the value function. Then we apply verification techniques to obtain the optimal allocation strategy in the feedback form and to study its properties. In the limit as the spectrum of market makers’ mean reversion rates approaches a gamma distribution, a volume-weighted average price execution under the resulting model generates a power-law expected execution price path. If time permits, we also discuss the extension of the problem to a trader maximizing a risk-adjusted profit and loss function.
