Shares are a good long-term investment with one hitch: they crash. If you want to make money during market crashes then you can buy volatility, which spikes during these crashes. Volatility can now be traded in the form of exchange traded products that are linked to the value of VIX in the US or VSTOXX in Europe. This book describes volatility and how it is traded in five chapters with many colour illustrations: "What is volatility?," "A brief history of volatility" charting volatility drivers since 1950, "How to invest in volatility" which lists volatility ETFs and ETNs and how they behave, "Volatility Trading Strategies" which describes some rules of thumb that have worked in the past, and "The future" which gives the author's opinion on how volatility will evolve in the coming years. The aim of the book is to help you decide whether to include volatility in your portfolio alongside traditional stocks and bonds.
