IAFE /Thalesians Seminar Series:
Option Hedging with Market Impact
A Talk by Robert Almgren

 

ABSTRACT
We consider the problem of a trader hedging a large options position. We use a realistic proportional market impact cost model, as is commonly used in optimal execution problems, rather than the bid-ask spread model which has been previously used. We also include overnight risk, which is important for an intraday hedge position. Our solutions solve a "pursuit problem", in which the actual hedge position moves smoothly in the direction of the perfect Black-Scholes hedge. We also obtain an expression for the modified volatility of the underlying caused by the hedge activity: if the hedger is long the option then volatility decreases and conversely if he is short. (Joint work with Michael Li, Princeton University.)

BIOGRAPHY
Robert Almgren, co-founder of Quantitative Brokers, providing agency algorithmic execution and cost measurement in interest rate markets, and Fellow in the Mathematics in Finance Program at New York University. Until 2008, Dr Almgren was a Managing Director and Head of Quantitative Strategies in the Electronic Trading Services group of Banc of America Securities. From 2000-2005, he was a tenured Associate Professor of Mathematics and Computer Science at the University of Toronto, and Director of its Master of Mathematical Finance program. Before that, he was an Assistant Professor of Mathematics at the University of Chicago and Associate Director of the Program on Financial Mathematics. Dr. Almgren holds a B.S. in Physics and Mathematics from the Massachusetts Institute of Technology, an M.S. in Applied Mathematics from Harvard University and a Ph.D. in Applied and Computational Mathematics from Princeton University. He has an extensive research record in applied mathematics, including papers on optimal trading, transaction cost measurement, and portfolio construction.

ABOUT THE SERIES
The IAFE's Thalesians Seminar Series is a joint effort on the part of the IAFE (www.iafe.org) and the Thalesians (www.thalesians.com). The goal of the series is to provide a forum for the exchange of new ideas and results related to the field of quantitative finance. This goal is accomplished by hosting seminars where leading practitioners and academics present new work, and following the seminars with a reception to facilitate further interaction and discussion.
