MFMOCMotley Fool Momentum Factor ETF

SEIMASEI QiM U.S. Large Cap Momentum Active ETF

In short

MFMO Momentum run through The Motley Fool's own index instead of one rented from MSCI or S&P. A house-built Momentum Factor Score picks the names, and the fee lands under the typical fund in this corner, above the giants.

SEIM Momentum with a chaperone. SEI's quant model buys U.S. large caps that have been running, then leans on quality, value and low volatility to sand off the edges, all for 0.15% a year.

Stated mandate

MFMO The fund seeks to track, before fees and expenses, the total-return performance of the Motley Fool Momentum Index.

SEIM The Fund seeks long-term capital appreciation by investing primarily in U.S. common stocks with relatively strong recent performance, using quantitative active stock selection and portfolio optimization.

Why people hold it

  • MFMO 0.50% a year undercuts the typical momentum fund in its peer group, where the median sits at 0.69%.
  • One job, stated plainly: track the Motley Fool Momentum Index, a rules-based screen built on the firm's own Momentum Factor Score.
  • Single-factor by design. Momentum is the entire thesis, so it slots beside a broad holding without muddying what you already own.
  • SEIM Charges 0.15% a year, a fraction of the typical fund in its active momentum peer group and level with the cheapest brand-name momentum ETFs like MTUM.
  • Not pure chase-the-winners: the prospectus model also weighs quality, value and low volatility, so recent strength gets vetted, not just ranked.
  • Roughly 70 names, concentrated enough for the factor to actually show up, run as an active quant mandate rather than a fixed index rebuild.
  • Stacks up as one of the stronger implementations among the systematic U.S. momentum funds we cover.

Worth knowing

  • MFMO Cheap for its cohort, not cheap outright. SPMO, VFMO and MTUM run momentum for a fraction of this fee.
  • A small fund that trades thinly, so bid-ask spreads can run wider than at the household-name momentum ETFs.
  • Launched in 2025, so the track record is short, and momentum strategies tend to lurch when market leadership rotates.
  • SEIM Momentum buys what has already moved. When market leadership rotates, this style can turn over quickly and trail the broad market.
  • Launched in 2022, so the live record is short and hasn't spanned many market regimes.
  • Mid-sized and moderately traded, so bid-ask spreads are worth a glance at the moment you trade.
