David Booth, Dave Butler, Eugene Fama, John McQuown, and Ken French explain the deep connections between academic finance and Dimensional’s approach to investing and how the firm’s focus on data and implementation, and its ability to adapt as research evolves, helps investors.
Our Interests are Aligned
David Booth and Robert Merton discuss the relationship between financial advisors and Dimensional.
Perspectives on Market Volatility
Dimensional thought leaders discuss principles that may help investors during periods of increased market volatility.
How Much Should I Save for Retirement?
Several factors may influence your retirement savings rate, including your expected retirement date, current level of income and savings, and retirement income goal.
Tuning Out the Noise
The right financial advisor can play a vital role in helping you tune out the media noise and focus on actions that can improve your investment outcome.
Taking a Fundamental Approach
Some clients are risk averse while others are risk seekers. Most are unaware of their own risk tolerance and we find it changes depending on market conditions — risk averse in down markets and risk seeking in up markets.
One of our responsibilities is to determine a client’s risk tolerance. We are also risk averse when creating asset allocation models and selecting investment vehicles. The only acceptable risks are those that are likely to generate adequate returns.
Spreading assets across different kinds of investments to reduce risk and potentially increase returns is perhaps the most important principle when investing. We diversify by sector, asset class, and correlation.
Before assets are invested, it is crucial to understand the time horizon. Obviously money that is needed in three months should be invested much differently than money that will be needed in ten years.
Time In, Not Timing.
It is virtually impossible to consistently predict whether the market will move up or down, and the risk of trying outweighs any possible rewards and are unlikely to increase long-term performance. Such practices are therefore avoided.
Strategic Asset Allocation
The portfolio as a whole is more important than individual funds. The appropriate allocation of capital among different asset classes will have far more influence on long-term results of the portfolio than the selection of individual funds.
Over 90 percent of investment returns are determined by how investors allocate their assets versus security selection, market timing and other factors.*

Modern Portfolio Theory
As recognized by the 1990 Nobel Prize, Modern Portfolio Theory is the primary influence driving the portfolio structure. For every risk level, there exists an optimal combination of asset classes that will maximize returns. A diverse set of asset classes minimizes risk. The asset class proportions determine the long-term risk and return characteristics of the portfolio as a whole.
Portfolio risk can be decreased by increasing diversification of the portfolio and by lowering the correlation of market behavior among the asset classes selected. (Correlation is the statistical term for the extent to which two asset classes move in tandem or opposition to one another.)
