AFOS vs DYNF

AFOSBARS Focused Opportunity Strategy ETF

DYNFAiShares U.S. Equity Factor Rotation Active ETF

In short

AFOS Active stock picking with no benchmark leash: ARS runs a focused, all-cap book of US companies it judges well-positioned and undervalued, and charges 0.46%, below the typical active US equity fund.

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.

Stated mandate

AFOS The fund seeks long-term capital growth through an actively managed portfolio that identifies well-positioned and undervalued companies across small-, mid-, and large-capitalization ranges.

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

Why people hold it

• AFOS Fee is 0.46%, with no waiver propping it up, and sits below the median for active US equity funds.
• Openly benchmark-free. The prospectus states the fund is not managed against any index or benchmark, so the portfolio can look nothing like the large-cap market.sec.gov
• Hunting ground is the whole US market cap ladder, small through large, not just mega-caps.
• Launched in 2025 and already holds assets in the hundreds of millions, landing in the upper half of a field of more than 100 active US equity funds.

• 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.

Worth knowing

• AFOS Thinly traded. Spreads can be wider and order size matters more than in heavily traded index funds.
• History starts June 2025, so there is only about a year of risk data behind it.
• Systematic rivals cost far less: DFAU at 0.12%, AVLC at 0.15%. You pay up here for a human making concentrated calls.

• 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.
