This book provides a guide to the complexities of modern finance. It describes the basics of investment and the sophisticated innovations of the modern financial system. It explains how the follies of finance have threatened the stability of the world economy, and describes an environment that is complex and sophisticated, but greedy, cynical and self-interested. This book explains how to put your finances in the only hands you can confidently trust - your own. Readers will learn everything they need to be their own investment manager. They will recognise their investment options, the institutions that try to sell them, and how to distinguish between fact and fiction in what companies say. They will discover the principles of sound investment and the research that supports these principles. Crucially, they will learn a practical investment strategy and how to implement it. Leading economist and hugely successful investor John Kay uses his academic credentials and practical experience to lay out the key principles of investment with characteristic clarity and dry humour. This is the only book about finance and investment anyone needs, and the one book they must have.
