To make this review more helpful, I figure I should I give a bit of background about myself. I am a 24 year old who started trading and following the market daily about 3-4 years ago. Moreover, I recently became more interested in options about a year ago and had been relatively successful, primarily through the use of selling puts (well described in the book). As someone who is quantitatively driven, I tried more complex option strategies through a simulated account but was not nearly as confident or successful with them and have yet to employ these strategies for real.
As I can assume was the case for many others, I discovered Rocco and his articles through Seeking Alpha. In particular, his articles regarding the use of options to double a simulated portfolio over a month, caught my eye. I have learned a lot through his articles and have done quite well using his research/insight as part of my analysis for various tech stocks. After reading his articles on Seeking Alpha, I became more comfortable with taking long positions in puts and calls. I enjoyed reading this book as it builds on the strategies his articles go over on Seeking Alpha and goes into the detail required for many of us. Personally, I enjoy his writing style and will recommend it to others I know looking to get into options trading.
However, just like investing in general, you should do your own research. Make sure you read the preview for the book and maybe read an article or two of Rocco's from Seeking Alpha. After looking over the negative reviews for this book, I can only assume that these customers did not do their research or have some personal issue against Rocco stemming from the Seeking Alpha message board (fairly common situation). If you read what I suggested above and are still interested, then you won't be surprised by the book's contents and should enjoy it too.
