Antti Ilmanen, author, Expected Returns: An Investor's Guide to Harvesting Market Rewards:
This wonderful book packs into two hundred pages the central elements you need for successful investing. Essentials include identifying long-run return sources you understand and can believe in, cost-effectively constructing well-diversified portfolios across them while respecting your constraints, and avoiding common behavioral pitfalls. You learn to appreciate the role of luck in realized returns and to look beyond luck by better understanding the systematic factors driving your portfolio—or any asset manager's portfolio. Read it!

This book takes a refreshing perspective: To excel at investment management, it is essential to identify the structural components of performance as well as the challenges of successfully executing on each component. This book should be required reading for any investor—whether institutional or individual.
