What Is DFAC? Dimensional U.S. Core Equity 2 ETF

Dimensional does not employ analysts forming views on individual companies. It applies rules derived from decades of academic work on which characteristics have historically been associated with higher expected returns: smaller size, lower relative price, higher profitability.

That places DFAC in an unusual category. It is not an index fund, because no published index defines its holdings. It is not a traditional active fund either, because nobody is making judgement calls about Nvidia's prospects. The label that fits is systematic, and the fee of 0.17% sits between the two worlds accordingly.

The top holdings are the same companies as any US core fund, at consistently lower weights: Nvidia 5.2%, Apple 4.8%, Microsoft 3.5%, Amazon 2.7%, Meta 1.8% and Alphabet 1.7%. Compare that to a cap-weighted fund where Nvidia alone can exceed 7%.

The weight has to go somewhere, and it goes down the size and value spectrum. Sector weights show it: technology at 30% against 37-39% in cap-weighted peers, with financials at 15% and industrials at 13% picking up the difference.

The consequence is predictable. In periods when mega-cap technology leads, DFAC lags a plain index fund. In periods when it does not, DFAC leads. Buying it is a decision to accept that tracking difference in exchange for a tilt you believe in over decades.

Someone who wants one fund for US equity, believes the size and value premia are real, and will not abandon the position during the multi-year stretches when the tilt hurts. That last condition is the binding one: a factor tilt held for three years is a coin flip, and the argument for it rests on horizons much longer than that.

Someone who simply wants the market at the lowest possible cost is better served by a plain cap-weighted fund at 0.03%. DFAC's 0.17% buys a deliberate deviation, and paying for a deviation you do not want is the worst of both.
