DFAU vs TOS

DFAUADimensional US Core Equity Market ETF

TOSCTwin Oak Strategic Solutions ETF

In short

DFAU Active management priced like an index fund. Dimensional spreads across roughly 2,400 US stocks, then tilts the weights toward value, profitability and momentum instead of simply mirroring the Russell 3000.

TOS Twin Oak's go-anywhere US stock fund: one active mandate that roams from mega caps to small caps, holds shares or whole ETFs, and can reach for derivatives. Launched January 2026 at 0.36% net of a waiver through December 31, 2026, under the typical active US equity fee.

Stated mandate

DFAU Seeks long-term capital appreciation. It uses an integrated research, portfolio-design, management, and trading process to build a broadly diversified portfolio of U.S. companies while balancing long-term return drivers, risk, shorter-term considerations, and trading costs.

TOS The Fund seeks total return through active management of domestic equity securities across all market capitalizations.

Why people hold it

• DFAU Charges 0.12% a year, well under the 0.65% median for active US equity funds and the cheapest of the top-graded names in its group (AVLC, DFAC, FELC).
• Holds roughly 2,400 US companies, so no single name steers the fund. Whole-market coverage, not a concentrated bet.
• Active without the stock-picking drama: it leans weights toward value, profitability and momentum, using the Russell 3000 as its reference point rather than a rigid rulebook.
• A multi-billion-dollar fund that trades actively, and one of the strongest overall implementations in its active US equity peer group.

• TOS 0.36% net of a waiver through December 31, 2026 undercuts the typical active US equity fee, though cheaper index-style peers exist, like DFAU (0.12%) and AVLC (0.15%).
• Wide mandate: US stocks of any size, held directly or through other ETFs (including Twin Oak's own), with derivatives permitted.twinoaketfs.com
• Total return is the stated goal, not a yield target or a single market-cap lane.twinoaketfs.com

Worth knowing

• DFAU Those tilts cut both ways: results can drift from a plain Russell 3000 fund for long stretches, in either direction.
• No published index behind it. The trade-off for flexibility is that you're buying Dimensional's process, not a public set of rules you can check line by line.
• Distributions land quarterly, not monthly, and the mandate is long-term capital appreciation rather than income.

• TOS The 0.36% is net of a waiver through December 31, 2026; gross is 0.76%, so the sticker price depends on that waiver staying in place.
• Thinly traded with a modest asset base, so spreads and order size matter more here than in the category's heavyweights.
• Launched January 2026, so the record is short, and the flexible toolkit (other ETFs, derivatives, affiliated funds) makes the holdings harder to eyeball than an index fund's.twinoaketfs.com
