Dimensional Fund Advisors (DFA) & Yeske Buie

Dimensional Fund Advisors

Dimensional Fund Advisors (DFA) was founded in 1981 by David Booth and Rex Sinquefield to apply academic research on capital market behavior to the practical world of managing investment portfolios. DFA maintains close links with the University of Chicago and other research centers for financial economics. Board members and consultants include some of the nation’s most distinguished academic theorists, including Eugene Fama, Kenneth French, Roger Ibbotson, Donald Keim, Nobel laureate Merton Miller, and Myron Scholes.

Dimensional Fund Advisors manages $315 billion and serves over 200 corporate, government, college endowment, charitable, and Taft-Hartley clients. Beginning in 1989, DFA began offering its low-cost institutional mutual funds to individual investors through a network of selected investment advisory firms. As one of these advisors, Yeske Buie plays a key role in educating clients about asset class investing, developing portfolio allocations to meet specific objectives, and helping them maintain the necessary discipline to ensure long term success. Dimensional Fund Advisors does not distribute its funds through direct marketing or conventional broker/dealer firms.

Investment Philosophy

Dimensional’s approach is firmly rooted in the belief that markets are “efficient”, and that investors’ returns are determined principally by asset allocation decisions, not market timing or stock picking. All portfolios employ a passive strategy designed to capture the return behavior of an entire asset class. DFA has no economists forecasting business cycles or interest rates, no investment strategists shifting allocations between stocks and bonds, and no analysts searching out “undiscovered” stocks.

While conventional index managers also employ this passive approach, DFA differs in several key respects. Dimensional funds do not necessarily track popular market benchmarks, but are designed to capture separate dimensions of worldwide returns which are accompanied by independent sources of risk. These dimensions are identified by rigorous academic research, often conducted by one or more of the leading financial economists with which DFA maintains a relationship.

DFA also places great emphasis on minimizing trading costs. Unlike conventional passive managers who replicate an index in mechanical fashion, Dimensional funds employ a sophisticated equity block trading strategy that allows for slight variations in day-to-day portfolio balance versus a market index in return for substantial cost reductions and hence improved total return. DFA claims to achieve negative trading costs in illiquid market sectors such as U.S. small company stocks.

In its ongoing effort to maintain the low expense characteristic of institutional mutual funds, Dimensional requires us to place client trades through one of several firms (e.g. Schwab Institutional) who maintain an “omnibus” account relationship with Dimensional and aggregate buy and sell orders on a daily basis. By adhering to this approach, we are able to purchase fund shares in amounts as small as $2,500, versus DFA’s published minimum of $2,000,000.

Dimensional Mutual Funds

All DFA funds are “no-load”, although certain international equity Portfolios levy a reimbursement fee of 0.50% – 1.00% on purchases. This fee is payable to the Portfolio, not Dimensional, and is intended to spread the burden of transaction costs in illiquid markets in the most equitable manner. In the absence of this fee, long term shareholders would suffer diminished returns due to trading activity of investors moving money in and out of a Portfolio.

Dimensional Fund Advisors focuses only on market dimensions where research documents a reward for risk taken. As a consequence, DFA offers no strategies investing in long-term bonds, non-investment grade debt, or “growth” companies since research has failed to identify attractive risk/return characteristics for these asset classes.


“Our deepest fear is not that we are inadequate. Our deepest fear is that we are powerful beyond measure. It is our light, not our darkness that most frightens us. We ask ourselves, Who am I to be brilliant, gorgeous, talented, fabulous? Actually, who are you not to be? Your playing small does not serve the world. There is nothing enlightened about shrinking so that others won't feel insecure around you. We are all meant to shine. And as we let our own light shine, we unconsciously give others permission to do the same. As we are liberated from our own fear, our presence automatically liberates others.” ~Marianne Williamson
