DYNF vs SURI

DYNFAiShares U.S. Equity Factor Rotation Active ETF

SURIFSimplify Propel Opportunities 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.

SURI A specialist healthcare stock-picker in an ETF shell. Simplify hands the keys to sub-adviser Propel, whose science team hunts global biotech, pharma, health tech and life-science names it believes investors have overlooked.

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.

SURI The Fund seeks long-term capital appreciation.

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.

• SURI A scientist's mandate, not an index screen: Propel sub-advises, using health sciences expertise to pick the names, and the fund is actively managed rather than tracking a benchmark.simplify.us
• Narrow on purpose: biotech, pharma, health care technology and life science tools, global in reach, with long-term capital appreciation as the stated objective.
• Live since 2023, so there is a real record of this team's picks to inspect instead of a backtest, inside standard 1940 Act ETF plumbing that pays quarterly.

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.

• SURI 2.56% net of a waiver through May 31, 2027, against 2.81% gross, well above the category median. Concentrated specialist research is what that fee buys.
• Thinly traded and modest in size, so getting in and out can cost more than with a broad index ETF.
• One slice of one sector, with no index anchoring it, means outcomes ride on the sub-adviser's judgment.
