Mike,
Is it that all the authors whose books you buy maintain web sites and hypothetical portfolios?
My perspective is that the maintanence of this shouldn't be that big of deal. The book points out the key is to identify long term trends and the companies that will benefit. The authors state that these trends are not that difficult to identify, and that the average investor can do so.
Perhaps we differ here, but I don't think the authors would think the pool of legitimate gorilla candidates would change very often. A gorilla candidate should be a more robust beast, with its legitimacy not teetering on a monthly or quarterly basis. The examples in the book lay out gorilla game historical scenarios, and the developments are measured in terms of years, not short term events. IMO.
I guess I really like the fresh approach put forth in the book, and I guess feel it deserves some follow-up on the author's parts. I guess I'm cynical in thinking they don't want to open themselves to performance-centered scrutiny, but if they want to defend this investment methodology I think they should provide a test portfolio.
Put another way, if their test portfolio had performed better, I think they'd still be pursuing it. Pointing to exceptional returns would certainly help sell more books. Since it didn't perform well they say they don't have time to update.
All IMHO.
