DYNF vs STRN

DYNFAiShares U.S. Equity Factor Rotation Active ETF

STRNCSMART Trend 25 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.

STRN A retirement advisor's momentum model, boxed into an ETF: 25 U.S. large caps ranked on the prior four quarters of price trend, benchmarked against the S&P 500. Concentrated by design, not by accident.

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.

STRN 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.

• STRN The process is legible: narrow the universe to a top half, keep the top quarter on trailing four-quarter price momentum and trend, then hold 25 U.S.-listed large caps.sec.gov
• At 0.59% a year it runs below the typical active U.S. equity fund (0.65% median) despite a hands-on, quant-ranked portfolio.
• Packages large-cap models the firm built for advisory clients into an exchange-listed wrapper, opened to smaller accounts.natlawreview.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.

• STRN Non-diversified with about 25 names, so a single top holding swings the fund far more than it would inside a broad index.sec.gov
• Ranking on recent price trend means it leans into what has already been working and swaps names as market leadership rotates. Turnover comes with the design.sec.gov
• A 2025 launch with a small asset base and thin trading: spreads can widen, and the live record is still short.
