Damodaran is widely known in the academic/financial arena. The second edition clears up many hiccups in the first edition. There are other books out there that will provide you with most of the information in this book, but not with as much detail and explanation. Also, this book is written very well. It does a great job of keeping the student's interest and not sounding too dry (most of the time). I bought this for one finance class, and have used it as a supplement in nearly all other finance classes. Every finance professor I have asked about Damodaran speaks very highly of him. Although this book material/methodology sticks primarily to the academic world, it still provides the reader with the real-world content and thorough understanding that will be needed in the business world. If you want a truly detailed yet practical analysis of valuation, then this is the book for you.
