A little better that average
I found this book a bit disappointing from the perspective of breadth of strategies, it covers really only S&P credit spreads, the authors speciality, as well as Ratio writes and ratio spreads in the commodity markets. These are not badly covered . I have always been impressed with John Summa's strategy articles at investorpedia.com covering delta neutral, calendar spreads and reverse calendar spreads , it would have be great to have these filled out a bit in this book instead of the 100 pages of filler material placed at the back of this book.
