Summary: Good classic on Real Option Theory
Review: A classic text on Real Option Theory. In comparison with Mr Copelands Text on Real Options, Trigeorgis has more depths, but Mr Copelands book is easier to read, as Copeland targets practitioners. The chapter on Real Options for the analysis of competetive strategies is worth reading, and much better than Mr Copelands remarks on that topic, but possibly not fully up to date. The future of real options seems to lie in their combination with game theory, CFROI and dynamic oligopolistic markets. Mr Trigeorgis describes that field of research in its baby stage, as the book is 6 years old, but his theories are still much better, than many other books on that topic.

Summary: Too unstructured
Review: I did not find this book hugely helpful. The explanations are just opaque enough to leave you frustrated that you have missed something. Ultimately this book is neither fish nor fowl: not deep enough for academic researchers and not practical enough for practitioners.

Summary: A really path-breaking work!
Review: It's a very good book, which has changed my way of thinking in some sense. Real options method is an exciting and challenging subject in corporate finance.For sure, it deserves more attention. Thanks for Mr.Trigeorgis'good job.

Summary: Excellent balance between theory and practice
Review: Lenos Trigeorgis' Real Options is probably the best book on real options analysis ... a theoretically superior alternative to discounted cash flow for valuing business projects ... that has been published thus far. It has a nice balance between theory and practice. The Copeland and Antikarov book has way too many errors to live up to the hype of being a useful "practitioner's guide." People with financial or quantitative backgrounds should be able to utilize Prof. Trigeorgis' book for practical valuation applications.

Summary: Sound Analysis on Pricing Your Options
Review: Real Options is the study of how to value potential business based on the real options they create rather than on discounting a simple stream of (erroneously) forecasted cash flows. Any business venture can be seen as a tangible corollary to a financial option, most commonly the Call or Put Option. For example, when Toyota and Honda build electric-fuel hybrid cars, they are not counting on an immediate stream of cash flows from hybrid car sales. Instead they are establishing a "Real" American Call Option on the ability to go to full hybrid car production ahead of the competition when the market for such vehicles manifests itself. How much they spend on their hybrid car programs is determined by finding the value of this option. Lenos Trigeorgis shows how this is done. Conceptually, one can follow it well enough, but Lenos is merciless with the math. Still, one can grasp the basic concept by studying this book. A good read on the subject.

Summary: Probably the most comprehensive book on the subject
Review: This book is probably the best to get a complete picture of real options concepts. Even if the mathematical concepts included in it are difficult to grasp (particularly once one reach continuous time models), the qualitative explanations give lots of examples that help to understand what the models accomplish, if not how they do it. Interactions of real options with strategy and game theory are also presented, which helps get a feeling of what the practical applications might be.

Summary: Excellent introduction to real options approaches
Review: This book is written by perhaps THE expert on real options. Dr. Trigeorgis walks the reader from traditional NPV through decision tree analysis, and finally through real options. Perhaps the most valuable discussions in the text concern the strategic and competitive ramifications of a real options mindset which traditional DCF apporaches do not capture. Highly recommended for academics and MBA finance professionals alike. Also serves as an excellent complementary text to other texts on the subject.

Summary: Good insight with strong mathematical background
Review: This is one of the first few books i reviewed during my recent dissertation on real options. I would rate it as an intermediate
to advanced text for those who are already familiar with real options and its ensuing mathematical formulation. Honestly it took me a while to figure out some of the maths ! Definitely not for the faint hearted.

Summary: By far the best RO book around
Review: Trigeorgis provides a rigorous treatment of the concepts that are required to facilitate understanding of RO. In fact, a section in Chapter 2 can serve as a reference for a half-semester course in corporate financial theory. Amram's book is a disappointment. Copeland's book is a good alternative for those that seek a readable introductory RO book. However, the edition that I got had numerous errors (check the book's website for corrections). Once you familiarize yourself with the concepts, upgrade yourself to the level of Trigeorgis.
