Past performance is not a guarantee of future results. Performance may increase or decrease as a result of currency fluctuations.

At Dimensional, our investment approach is based on a belief in markets.

Rather than attempting to predict the future or outguess others, we draw information about expected returns from the market itself—leveraging the collective knowledge of its millions of buyers and sellers as they set security prices.

Trusting markets to do what they do best—drive information into prices—frees us to spend time where we believe we have an advantage, namely in how we interpret the research, how we design and manage portfolios, and how we service our clients. We take a less subjective, more systematic approach to investing—an approach we can implement consistently and investors can understand and stick with, even in challenging market environments.

   Embrace Market Pricing

The market is an effective information-processing machine. Each day, the world equity markets process billions of dollars in trades between buyers and sellers—and the real-time information they bring helps set prices.

Daily averages were computed by calculating the trading volume of each stock daily as the closing price multiplied by shares traded that day. All such trading volume is summed up and divided by 252 as an approximate number of annual trading days.

    Eugene Fama’s efficient market hypothesis marks a pivotal moment for modern finance. The essence of the argument can be described by the simple statement that security prices reflect all available information.

    The ICAPM set up a theoretical framework for how multiple sources of risk could arise. It expanded on the one-period CAPM model where the only priced risk was market beta.

  • Today
    Dimensional’s Research and Investment teams draw insight from academia, but what sets us apart is how we interpret, test and apply that research to practical investment solutions for our clients.
  • Tomorrow
    Dimensional was built around a set of ideas bigger than the firm itself. With a confidence in markets, deep connections to the academic community and a focus on implementation, we go where the science leads, and continue to pursue new insights, both large and small, that can benefit our clients.

Dimensional’s investment approach is grounded in economic theory and backed by decades of empirical research.

Our internal team of researchers works closely with leading financial economists to better understand where returns come from.

Research has shown that securities offering higher expected returns share certain characteristics, which we call dimensions. To be considered a dimension, these characteristics must be sensible, persistent over time, pervasive across markets, and cost-effective to capture.

The Evolution of Indexing and Dimensional
Eugene Fama
Eugene Fama
Nobel laureate, 2013 Professor, University of Chicago; Dimensional Director; Consultant, Dimensional Fund Advisors LP
“We’re very careful in looking at new research that comes along and making sure it’s robust.”

Understanding what drives returns is the starting point. From here, we focus on fine-tuning our method of capturing them.

We structure broadly diversified portfolios that emphasise the dimensions of higher expected returns, while addressing the tradeoffs that arise when executing portfolios.

Every day our portfolio managers and traders seek to balance costs against expected returns and diversification. We work for the slightest expected gain, as every incremental improvement can add up over time.
