Engineering
In Dimensional's view, the road to investment success lies in identifying the risks that appear to be priced, choosing how much of these risks to take, and then striving to minimise the risks and costs imposed by traditional approaches. Science-based portfolio engineering makes this possible.
Dimensional designs strategies that offer focussed exposure to the risk dimensions of the market in fully diversified portfolios. Unlike index funds that follow commercial benchmarks, Dimensional defines asset classes based on a security's market capitalisation and/or book-to-market (BtM) ratio and applies our own eligibility rules. To gain the purest representation possible, we exclude securities that do not exhibit the general characteristics of the defined asset class. We also eliminate securities that lack sufficient liquidity for cost-effective trading.

Engineering portfolios around broadly defined risk factors regularly generates opportunities for Dimensional traders to add value. Rather than replicate an index in mechanical fashion, we permit deviations from market cap weightings and allow for the integration of stocks among asset classes. This flexibility also allows us to reduce transaction costs caused by counterproductive trading. For asset classes defined by size, a slightly higher hold or "buffer" range allows Dimensional to hold securities that commercial indices are forced to sell, which reduces turnover and can increase returns.
