Most "investment advice" books suffer from poor editing, both of the 'grammar & syntax' variety, and, more distressingly for this genre, flat-out incorrect information. Klines's book is no exception- the grammar & syntax are fine, but her book is replete with factual errors and misstatements. For example, on page 207, she defines a synthetic long futures as "sell a call option, buy a put option." Wrong. That is a synthetic short position. Similar errors pervade the book.
One useful feature is chapter 3, which presents futures contract specifications. However, even here, some of the information is occasionally confusing or misleading.
This book is published by McGraw-Hill, a highly reputable house. My surmise is that McGraw-Hill has no financial experts on its editorial staff; otherwise, it wouldn't tolerate the publication of such a sloppily-edited piece. Disappointing!
