This book and John Cochrane's "asset pricing" complement each other very well. Bossaerts discuss extremely important and overlooked issues in asset pricing theory and empirics in a very compelling way.
As a practitioner with an advanced degree, i found it a valuable read, and recomend "the paradox" to any serious finance practitioner or graduate student.
Let me end quoting the book (p.84):
"Asset pricing theory is both elegant and logically compelling. It is a nice piece of applied mathematics. But this is not suficient to conclude that it has scientic merit. To establish the latter, its predictions need to be verified in a variety of contexts."
Couldn't agree more.
