Quality. We all make judgments about it every day. Yet articulating a clear definition of quality in an investing context is challenging. This book addresses the challenge, and distills years of practical investing experience into a definitive account of this under-explored investment philosophy. Finance theory has it that abnormal outcomes do not persist, that exceptional performance will soon enough become average performance. Quality investing involves seeking companies with the right attributes to overcome these forces of mean reversion and, crucially, owning these outstanding companies for the long term. This book pinpoints and explains the characteristics that increase the probability of a company prospering over time - as well as those that hinder such chances. Throughout, a series of fascinating real-life case studies illustrate the traits that signify quality, as well as some that flatter to deceive. The authors' firm, AKO Capital, has a strong track record of finding and investing in quality companies - helping it deliver a compound annual growth rate more than double that of the market since inception. Quality Investing sheds light on the investment philosophy, processes and tough lessons that have contributed to this consistent outperformance. "Investing is a continuous process of learning, and it will be a rare investor who does not glean substantive lessons from the notable AKO story of quality investing.";- Stephen Blyth, President and CEO, Harvard Management Company, Professor of the Practice of Statistics, Harvard University; "Capturing both the science and the art that have driven AKO's success, Quality Investing is equal parts investing handbook and ode to the beauty of truly great businesses."; Peter H.

If you are a long term investor, it's hard to find a more important factor as to what will power your ultimate investment returns. That said, quality is impossible to measure with precision because it often embodies more subjective qualitative factors than easily quantifiable measurements. Quality is also dynamic and changes over time. This book attempts through case studies, descriptions, and quantifiable measurement to help investors think systematically about quality and its importance. Enjoy!";- Thomas S.
