DYNF vs TOS

DYNFAiShares U.S. Equity Factor Rotation Active ETF

TOSCTwin Oak Strategic Solutions ETF

In short

DYNF Most factor funds make you pick a lane: value, momentum, quality. DYNF rotates across five styles instead, letting a factor model decide which one leads, and charges an index-fund-ish 0.26% to do it.

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

DYNF The Fund seeks to outperform the U.S. equity market through diversified, tactical exposure to style factors using a factor rotation model.

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

Why people hold it

• DYNF Five style factors in one ticket (value, quality, momentum, growth, low volatility), reweighted by a rotation model rather than locked to a single tilt.
• 0.26% is well under half the median fee in its active US equity peer group, which is unusual pricing for a strategy with a human-supervised model behind it.
• A multi-billion-dollar fund and one of the more actively traded names in its category, so getting in and out rarely becomes the hard part. Pays quarterly.
• Running since 2019 under one of the biggest ETF shops, and it stands among the strongest overall implementations in the active US equity group we track.

• 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

• DYNF The yardstick isn't the S&P 500: it's a custom blend of 80% MSCI USA and 20% MSCI USA Minimum Volatility, so a low-vol tilt is baked into the benchmark itself.
• Active by design. The factor mix shifts, the book runs to a couple hundred stocks, and a rotation call can leave it out of step with a plain US market index fund.
• Cheap for active, not the cheapest shelf: systematic peers DFAU (0.12%), AVLC (0.15%), DFAC (0.17%) and FELC (0.18%) all undercut it on fee.

• 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
