The full name:
Active Portfolio Management: A Quantitative Approach for Producing Superior Returns and Selecting Superior Returns and Controlling Risk

by Amazon, this 2nd edition was published in 1999.
In light of the 1999 - Today cycle, I am guessing this book is perhaps obselete.
Correct me if I am wrong.

Btw, where is the book?

thanks for sharing it.
