This case discusses the unique value proposition of Dimensional Fund Advisors (DFA), which used academic research to create specialized portfolios focused on Small Capitalization companies. Their investment philosophy particularly focused on research by Fama and French and Banz. They researched how small cap companies tend to outperform large cap companies over time. In addition, FDA created an additional competitive advantage by created trading efficiencies to reduce transaction cost.

1. Fama and French findings shocked the modern portfolio theory and their study was nick named "Beta is Dead". With respect to CAPM they found that stocks with high betas did not have consistently higher returns than low-beta stocks. Furthermore, Fama and French concluded that a high book value to market value was the most important variable related to predicting high stock returns on small cap stocks. These findings were published in a 1992 paper titled "The Cross-Section of Expected Stock Returns".

2. DFA's business strategy centers on the core concept that markets are "efficient" – that is that no one has the ability to consistently pick stocks that would beat the market. In addition, the founders of DFA believed that combining solid academic research with the abilities of skilled traders would complement each other to produce superior returns. DFA's Small Cap objective is to deliver the size effect (research has indicated that small companies provide higher expected returns than larger companies in the long term) and provide the diversification benefits of investing in small companies worldwide. Dimensional defines small companies as those whose market capitalization comprises the smallest 12.5% of the total market universe. On a quarterly basis, the market capitalization ranking of eligible stocks is examined to determine which issues are eligible for purchase and which are sale candidates. The US Micro Cap Portfolio invests in securities of US companies whose size falls within the smallest 4% of the total market universe. The US Small Cap Portfolio invests in securities of US companies whose size falls within the smallest 8% of the total market universe.

Dimensional's value strategies are based on the Fama/French research in multifactor portfolios designed to capture the return premiums associated with high book-to-market (BtM) ratios.
