CONTENTS
While there are many different aspects to volatility trading, not all of them are suitable for all investors. In
order to allow easy navigation, we have combined the sections into six chapters (plus Appendix) that are
likely to appeal to different parts of the equity derivatives client base. The earlier chapters are most suited
to equity investors, while the later chapters are aimed at hedge funds and proprietary trading desks. We
have tried to explain the topics assuming the least amount of prior knowledge, but swiftly move onto
advanced areas in order to add the most value.
