Group discussion on Problems in finance
John-Paul Broussard – (Rutgers University)
Natalie Packham (Frankfurt School of Finance & Management)

Over time, financial professionals have dealt with numerous ways to approach extreme movements in markets. We have gone from looking solely at univariate perspectives, using both parametric and non-parametric approaches, to bi-variate considerations, and now multivariate portfolio perspectives. How should an institution reorient itself to extreme market, credit, operational, liquidity and other events? What should an institution do to take into account the potential “correlation breakdown” when multiple extreme risks occur simultaneously? Who at a financial institution needs to keep an eye on the potential devastation caused?

The purpose of this Group Discussion is to elicit ideas on which severe outcomes should be considered, how to evaluate the problems those extreme outcomes potentially generate, and certainly, which approaches to take that offer the best risk-return trade-off given the problems of extremes facing institutions.

Summary of the group discussion :

A small but lively group gathered to discuss current and ongoing problems in finance that can be analysed and solved using techniques from extreme value theory. The discussion focused on the feasibility of tail-risk protection strategies employing extreme value theory methods in market environments where classical protection strategies such as protective put are not effective. Participants thought creating an index of tail risk protection strategies may add value. Since there are multiple vehicles employed, an index representing multiple protection strategies may be one way to evaluate risk management effectiveness. Generally, the group expects extreme value theory continues to spread from the purely academic realm to practical applications in the finance industry.
