An analysis of Delta variant hedging impact on intraday asset price dynamics 

Seminar by Dori Levanoni

14th September 2021 – On-Line

In this seminar Dori Levanoni will discuss the impact of listed options market makers on the dynamics of intraday asset prices.
Most financial market participants have objectives which are difficult to determine so their trading behaviour can be quite difficult to model. Listed options market makers, however, have very clear and nearly singular objectives prescribed by both their internal risk controls and regulatory requirements. This means we may be able to model their trading behaviour and so their impact on market prices fairly well.

Two recent papers – references are below – study their behaviour and their impact on the dynamics of intraday asset prices as a result of their delta hedging. However, the methods used to estimate the dealers’ gamma positions (which determine their delta hedging needs) are much stronger for individual security options than they are for index options.

This seminar will analyse those proxies for index option dealer gamma positions and compare / contrast them with much finer estimates to see if their ability to predict those dynamics stands up.
