DYNF vs RULE

DYNFAiShares U.S. Equity Factor Rotation Active ETF

RULEFAdaptive Core 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.

RULE RULE is the algorithm with an exit button: a price-trend model ranks a go-anywhere lineup and can shift the whole portfolio to cash when signals break. The ticker is the pitch; 1.84%, with no fee waiver, is the toll.

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.

RULE The fund seeks long-term growth of capital while also pursuing income.

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.

• RULE Its price-trend model scores assets and can move the entire portfolio into cash or money-market ETFs when signals turn down, a sell discipline most all-equity peers skip.sec.gov
• Go-anywhere by charter: stocks of any size, plus equity and fixed-income ETFs, so one ticker covers ground that usually takes several.sec.gov
• Concentrated rather than sprawling, at roughly 40 positions, so each pick carries real weight.
• Benchmarks itself to the S&P 500 Total Return Index, a yardstick you already know.

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.

• RULE Costs 1.84%, with no fee waiver in place and above the category median; two of the category's standouts run far cheaper, DFAU at 0.12% and AVLC at 0.15%.
• Frequent trading is built into the strategy, which the prospectus flags for higher transaction costs and bigger tax bills in a taxable account.sec.gov
• A small fund that trades lightly, so spreads can run wider than at the category's giants.
