What Is Dimensional Financial Advisors?

Dimensional Financial Advisors is a global investment management firm that designs and manages mutual funds and exchange-traded funds (ETFs) based on academic research in finance and economics.

The company focuses on:

  • Long-term investing

  • Diversification

  • Risk management

  • Low costs

  • Evidence-based strategies

Unlike many asset managers that try to predict market movements, DFA builds portfolios designed to capture broad market returns while tilting toward specific factors such as company size, value, and profitability.

Dimensional primarily works through financial advisors rather than selling directly to individual retail investors.


The Investment Philosophy of Dimensional Financial Advisors

At the core of Dimensional Financial Advisors is an investment philosophy grounded in decades of financial research. DFA’s strategies are influenced by academic studies from Nobel Prize–winning economists and finance professors.

Key principles include:

1. Markets Are Generally Efficient

DFA believes that market prices already reflect available information. Instead of trying to beat the market through timing or stock picking, the firm focuses on capturing long-term market returns.

2. Risk and Return Are Related

Higher expected returns come with higher risk. Dimensional structures portfolios to target certain risk factors that research suggests may offer higher long-term returns.

3. Diversification Is Essential

DFA portfolios invest across thousands of companies and multiple asset classes to reduce exposure to any single stock or sector.

4. Discipline Matters

The firm emphasizes staying invested through market cycles rather than reacting emotionally to short-term volatility.


How Dimensional Financial Advisors Builds Portfolios

Dimensional Financial Advisors designs portfolios using factor-based investing. Factors are characteristics of stocks and bonds that research shows are associated with long-term performance.

Common factors include:

  • Company size (small vs large firms)

  • Value (low price relative to fundamentals)

  • Profitability

  • Investment patterns

  • Market exposure

Rather than tracking a standard index exactly, DFA funds tilt toward these factors while maintaining diversification.
