BROL vs DYNF

BROLBBaron Risk Optimized Large Cap ETF

DYNFAiShares U.S. Equity Factor Rotation Active ETF

In short

BROL Baron has picked growth stocks since 1982. BROL is the buttoned-up version: the same bottom-up research, wrapped in a risk framework targeting low beta and low tracking error so the portfolio strays less from its large-cap benchmark.

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

BROL The Fund seeks capital appreciation.

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

• BROL Active management for 0.45% a year, against a 0.70% median for US active equity funds. Cheap-for-active pricing on a strategy built around Baron's own stock research.
• Risk optimization is the product, not a footnote: defined parameters for beta, growth factor exposure and tracking error sit on top of the stock picks.businesswire.com
• Run by Michael Lippert, a Baron portfolio manager and its head of technology research, inside an active ETF lineup from a firm that has invested this way since 1982.businesswire.com

• 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

• BROL Launched in 2026, so the track record is short, the asset base is small and trading is thin. Spreads can run wider than on the giant funds sharing its shelf.
• Cheap for active is not cheap outright: systematic large-cap peers such as DFAU (0.12%) and AVLC (0.15%) charge a fraction of it.
• Low tracking error cuts both ways: the design keeps the fund close to large-cap growth rather than dramatically different from it.businesswire.com

• 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.
