At the peak of the dot-com bubble, buying Internet stocks was momentum investing at its most pure - get in when a new stock or sector is on its upswing, and get out while the gettin's good. But Peter S. Cohan has created new criteria for Internet investors to apply in the traditional method of fundamental analysis. Instead of looking to old-line gurus like Graham or Buffet for advice, Cohan draws on the business strategies of John D. Rockefeller to come up with fresh e-commerce attributes like economic leverage, closed-loop solutions and adaptive management for investors to measure. We [...] recommend this book to executives, employees and students with equal vigor, although consider yourself forewarned that Cohan's extended barking-dog analogy will grate on your nerves. Nevertheless, anyone who invests in Internet companies or even traffics in Internet commerce for business or pleasure will gain insights from this book, regardless of whether Cohan's investment criteria prove to have staying power.

Practical and effective. A balanced book with an understandable writing and depth of analysis.

This book is good for Newbie to the internet but certainly don't worth a look for someone looking for insight.

The framework is nothing new but more or less a simplified business plan.

In Chapter 13, Advice for Internet Management and Investors sounds like a common sense and existing strategy using by most of the dotcom. Common Sense: Strategy 1 of those advices is moving the company into a more profitability region in short. (It dividies the market into 3 levels of profitability. so called Lossware, Brandware and Powerware. Well, no matter if it is New or Old economy, there is always different degrees of profitability.)

Existing strategies: Selling out of a porfolio builder, deep pockets and restructuring. We are seeing consolidation in the market a long long time ago and a lot of big or small players already know it is the way.

This book is more like a news reporting and a lot of newly invented words cannot make this book a standard of new economy rules but disappoint me only.

This is the most lucid, sensible analysis I've read thus far of the likely implications of engaging in e-commerce from different strategic perspectives and business models. Cohan provides a valuable framework and applies it to scores of real cases. I find myself returning to his book time and again to apply his methodology. His only off-base advice: don't invest in companies led by folks over 35. I'll forgive him that one. The rest of the book is a real gem. It should age well.

This book is a "must read" for anyone with an interest in developing a strategic understanding of the business world surrounding the internet. It is not just a collection of unrelated stories about e-commerce and technology. Peter Cohan provides a very insightful and practical framework for evaluating investments in various dimensions of internet business. He de-mystifies many of the key technology aspects of the internet with concise industry segmentation and the use of familiar, yet powerful, business language. His research into the role and influence of venture capital firms is great! There is something useful in this book for everyone from the CEO in almost any industry down to the business student.
