My name is Rick Ferri. I’m a financial analyst, hourly-fee investment adviser, and creator of this website.

I started the Core-4® investing concept in 2007 to provide the public with free, well-constructed portfolios of a few low-cost index funds and exchange-traded funds (ETFs). Core-4® portfolios are broadly diversified, easy to implement, simple to maintain, have low fees and low taxes, and the best thing is you can manage them yourself. Invest in one or invest in more. Use them as-is or add a personal touch

These simple portfolios outperform complex strategies promoted by fund companies and advisers who make investing complicated for the sake of collecting evergreen fees. The index funds and ETFs suggested for Core-4 Portfolios™ are widely available through any US brokerage firm and many international firms. If you prefer the help of an adviser, I provide guidance through my hourly-fee service at

Simple investing is a virtue – the ultimate in portfolio sophistication. Let’s get to the core of an investment strategy that works for you!


I have been helping investors for 30 years as an adviser, researcher, author, speaker, and mentor for advisers. My books include All About Index Funds, All About Asset Allocation, The ETF Book, The Power of Passive Investing, Serious Money, and a forthcoming book, A Few Good Funds: The Genious of Simple Investing. I co-edited The Bogleheads’ Guide to Retirement Planning and am the host of the Bogleheads on Investing podcast featuring the top movers and shakers in the investment industry.

The first Core-4® portfolio was introduced on the forum in 2007 – the Classic Core-4 Portfolio. This strategy offered broad stock, bond, and real estate exposure utilizing only four index funds. The concept proved to be robust and found wide acceptance among investment bloggers and in the print media. Public agencies also took notice. The Texas State Securities Board features the Classic Core-4 Portfolio in the Texas Investor Guide, Strategies for Investing Wisely and Avoiding Financial Fraud. I have since added several alternative Core-4 Portfolios to meet the growing needs of individual investors as they discover the benefits of Core-4® simplicity, transparency, affordability, and reliability.
