What it argues
All About Asset Allocation is Richard Ferri's systematic guide to building and maintaining a diversified investment portfolio. Ferri is a fee-only financial advisor and a longtime advocate of low-cost index investing in the Bogle tradition. The book is neither philosophy nor polemic — it is a practical, data-heavy manual that walks through each major asset class, explains the historical return and risk characteristics of each, and shows how combining imperfectly correlated assets reduces portfolio volatility without sacrificing expected return.
The central argument is that asset allocation — how you divide a portfolio among stocks, bonds, real estate, and other assets — is the primary driver of long-run investment outcomes. Security selection and market timing, which dominate most investment conversation, are far less important. Ferri backs this with the standard academic literature on portfolio theory: work by Markowitz, Fama, and French that has been replicated consistently for decades. The practical implication is that most investors should spend their time choosing an allocation that matches their risk tolerance and time horizon, then automate the rest.
What it gets right
- 1.
Asset allocation — the split between asset classes — explains more of long-run portfolio performance than security selection or market timing.
- 2.
Combining assets with low or negative correlations reduces portfolio volatility without reducing expected return, the core benefit of diversification.
- 3.
Low-cost index funds are the most reliable implementation vehicle for any asset allocation strategy, because costs compound against returns over decades.
