Financial markets are a fascinating example of 'complexity in action': a real-world complex system whose evolution is dictated by the decisions of crowds of traders who are continually trying to win in a vast global 'game'. This book draws on recent ideas from the highly-topical science of complexity and complex systems, to address the following questions: how do financial markets behave? Why do financial markets behave in the way that they do? What can we do to minimize risk, given this behavior? Standard finance theory is built around several seemingly innocuous assumptions about market dynamics. This book shows how these assumptions can give misleading answers to crucially important practical problems such as minimizing financial risk, coping with extreme events such as crashes or drawdowns, and pricing derivatives. After discussing the background to the concept of complexity and the structure of financial markets in Chapter 1, Chapter 2 examines the assumptions upon which standard finance theory is built. Reality sets in whith Chapter 3, where data from two seemingly different markets are analyzed and certain universal features uncovered which cannot be explained within standard finance theory. Chapters 4 and 5 mark a significant departure from the philosophy of standard finance theory, being concerned with exploring microscopic models of markets which are faithful to real market microstructure yet, which also reproduce real-world features. Chapter 6 moves to the practical problem of how to quantify and hedge risk in real world markets. Chapter 7 discusses deterministic descriptions of market dynamics, incorporating the topics of chaos and the all-important phenomenon of market crashes.

This handbook looks at the Fourth Wave of coaching – ‘in’, ‘with’ and ‘for’ nature. It presents a comprehensive overview and practical set of emerging practices in coaching related to the environment, nature and the climate, and reflects a wider move towards outdoor and nature coaching as an antidote to the over-reliance on digital and AI technologies.This next book in the acclaimed Coaches’ Handbook Series brings together internationally respected coaching experts and practitioners to share the most up-to-date and evidence-based knowledge. It explains the background to the practice influenced by movement, senses, embodied practice and nature connection across different cultures. It explains the benefits across different coaching methodologies, with a focus on Eco and Blue-Green Psychology, and places the important topic of climate at the centre of coaching individuals and teams. The handbook incorporates a comprehensive set of tools and techniques in order to assist coaches in applying different approaches. For example, how to facilitate deep nature connectedness and biophilia (bringing the outdoors indoors), through the use of metaphor, weather, landscapes and serious nature play. The book concludes with a number of case studies of how outdoor and nature coaching has had positive outcomes across different groups.Aimed at coach practitioners, their supervisors, trainers and student coaches on accreditation programmes or undertaking training for a certificate in coaching, the book brings to life this vitally important and energising coaching practice.
