Few investors beat the market consistently. Those who do are held in high esteem. In truth, there seem to be few common denominators, at least on the surface, among successful investors. They use very different investment strategies and subscribe to very different and, at times, contradictory views of how markets work and what leads to investment success. This revised and fully updated edition of Investment Philosophies covers different investment philosophies with the intent of finding the beliefs that underlie each one, the evidence on whether the strategies that emanate from the philosophy work and what an investor will need to bring to the table to make the philosophy work. It covers indexing, passive and activist value investing, growth investing, chart/technical analysis, market timing, arbitrage, and many more investment philosophies. The problem is that most investors have already chosen a philosophy and are uninterested in reading the details about the others. This book breaks the philosophies down, and provides investors with helpful online resources and tools to fully investigate each investment philosophy and assess whether it is a philosophy that makes sense for them.
