Query: Great book - for the gullible and simple minded

Aside from the obnoxious advertising for Cook's dubious seminar business, the foundation of this book is fundamentally flawed. Of course it looks easy buying at the low and selling at the high when you look at a HISTORICAL chart - it already happenned! Doing so in the future is much more difficult, and the truth is these "strategies" are more wishful thinking when someone tries to enact them in a real portfolio over the long term. Witt/Cook don't cover some important aspects of bid/ask spread, fundamental reasons for volatility, etc. Refer to Cook's early books, and you'll note that of the dozen or so stocks he uses to illustrate his "rolling stock" concept, three are now bankrupt and all but one are now down at least 40% from where they were in 1996. Strange, but for those who bought these "rollers", there was never a chance to sell at the high...This book is full of wishful thinking, no matter how eloquent it sounds.
