DFTT vs SEIM

DFTTCDF Tactical 30 ETF

SEIMASEI QiM U.S. Large Cap Momentum Active ETF

In short

DFTT Most momentum funds smear the factor across hundreds of stocks. DFTT goes the other way: a formulaic index ranks the 100 largest U.S. companies on price momentum and keeps just 30. Concentrated, rules-driven, and brand new (it launched in November 2025).

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

DFTT The fund seeks long-term capital appreciation by tracking a formulaic index that allocates to 30 of the largest 100 U.S. stocks using price momentum.

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

• DFTT Concentration by design: the index ranks the 100 largest U.S. stocks on price momentum and holds 30 of them, so the leaders carry real weight instead of being diluted.
• The process is written down. A published benchmark, the DF Risk-Managed Tactical 30 Index, does the selecting, so the portfolio doesn't hinge on a manager's gut call.
• Large-cap universe only: momentum is applied inside the 100 biggest U.S. companies, so the names are familiar blue chips rather than small-cap flyers.

• 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

• DFTT At 0.70% the fee sits near the middle of the active momentum crowd, while index rivals SPMO, MTUM and VFMO run 0.12% to 0.15%. The tactical rules carry a price tag.
• It launched in November 2025, so the public record is short and the fund is still small and lightly traded, which usually means wider bid/ask spreads than category giants.
• Thirty names means each one matters: a single stock's move lands harder here than in a momentum index spread across hundreds of holdings.

• 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.
