The book has all kinds of details such as the information discussed during their 2003 secular forum; the logic behind the way different types of news are processed; the people at PIMCO; the proportion of short treasuries, long treasuries, high-quality corporates, junk bunds, developed world debt, emerging markets debt and TIPS in a portfolio when rates are declining, raising or stable. The book also talk about the gamblers, speculators and financiers who have inspired Gross.
Most of these details have no bearing on us derivate traders until one of them becomes particularly pertinent such as the news mentioned yesterday and today by Bloomberg that Lehman is adding more long treasuries to it's bond index. After reading the book, it is easier to understand why one should expect a lot of bond managers to buy long treasuries right now.
The most value I found is in the examples of how Gross was responding to changes in Fed policies and economic developments abroad, and how data and analyses are separated between secular and cyclical forecasts. Sometimes I get all tangled up between bullish and bearish signals, and being able at times (not all the time) to separate my signals between long-term and short-term movements helps me manage conflicting information.
