"Experts Versus the Evidence: A Practical Guide to Stock Investing brings together the ideas and successes of experts and the potential of data to give readers the opportunity to learn from the best and to put their insights into practice. Readers will learn two important aspects of financial investment: first, the formulation of investment philosophies; second, how to test and implement data-driven investment strategies on one of the most popular professional, financial, digital platforms. This investment textbook is unique compared to existing textbooks in two important ways. First, instead of focusing on academic theory, it concentrates on the investment philosophies of well-known experts, looking into their ideas and explaining them in the context of economic and finance theories. Second, unlike the books on the stories surrounding investment gurus, evidence and tools are presented to replicate, test and implement their strategies. While this book is concerned with the lessons to be learnt from investment experts, it is also interested in presenting relevant evidence on the various investment approaches (i.e. what could have been achieved by a specific approach over recent years).

The presentation of evidence has two objectives: first, do the claims of an expert now stack up? Second, how might an approach be quantified so it can be tested against data? This allows the reader to look at an approach and it see how it can be applied to modern data and techniques of testing. The evidence in each chapter is a prelude to the Bloomberg appendix that accompanies it. These appendices are step by step guides to using Bloomberg to action a strategy that replicates that of an expert -- not always perfectly but as closely as is possible. By the end of the book, students and investors with access to Bloomberg will be comfortable with accessing data and developing customized investment strategies. A companion website will host supporting material such as links to key information about the experts, s elected updated investment screening results of the strategies described in the book, investment and Bloomberg technical quizzes, additional discussion of style/factor investing which has been inspired by the experts and information about investment competitions."--.
