The firm has adopted a highly concentrated, core-satellite investment strategy heavily weighted toward passive factor investing.

Key Holdings

The portfolio is overwhelmingly anchored by DFSU (Dimensional U.S. Core Equity 2 ETF), which constitutes a massive 52.18% of the total assets ($235.57M). This level of concentration in a single fund indicates that the manager views this vehicle as a sufficient proxy for the bulk of their U.S. equity exposure, likely relying on its multifactor model to drive returns.
