Unperturbed by Volatility
A Practitioner's Guide to Risk
Description:... Central to all investment allocation and risk management is being clear on what risks one is being compensated for in the reward delivered. In an era of increasingly interlaced markets, assessing this correctly is paramount, but often used measures such as volatility can in practice be inadequate and misleading without other serious and often more important considerations.
Unperturbed by Volatility takes a deep look at the essential features of real-world financial markets, analyzing the strengths and the limitations of various metrics, techniques and methods, where these can be tweaked to work, where metrics such as volatility break down, and where in practice we must seek constructions that make such errors manageable.
Primary themes also include the limits of data, and the role of market extremes - both up and down and in both risk and opportunity. Relevant issues are diagnosed within a consistent framework that forces market realities to the fore and from which useful conclusions can be drawn. All available market instruments are put to full use.
Unperturbed by Volatility is built on strong theoretical grounds and practical insights. Drawing on applicable elements from diverse quantitative disciplines, from probability theory to statistical tools to quantitative finance and others, the book requires some prior knowledge but its delivery is not heavily mathematical. The simple, robust and useful is given preference over the technically fancy.
