MEMEDRoundhill Meme Stock ETF

SEIMASEI QiM U.S. Large Cap Momentum Active ETF

In short

MEME Most momentum funds rank stocks on past price strength. MEME ranks on options-implied volatility, holding roughly 25 of the most heavily traded, most feverishly priced US names. The retail crowd trade, packaged as a plain equity fund.

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

MEME The Fund is an actively managed ETF seeking exposure to meme stocks. It screens highly traded U.S.-listed stocks and ADRs and selects the 25 with the highest implied volatility.

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

  • MEME A genuinely different screen from the rest of the momentum shelf: it sorts heavily traded US stocks and ADRs by implied volatility, not by trailing price gains.
  • Concentrated on purpose. Around 25 names means the meme trade actually shows up in the portfolio instead of being diluted across hundreds of positions.
  • The fee (0.69%) sits right at the median for its actively managed momentum cohort, so the novelty does not come with a novelty markup.
  • Simple plumbing: a registered 1940 Act fund holding US stocks outright, listed on NYSE Arca, not a leveraged or derivatives-based trading vehicle.prnewswire.com
  • 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

  • MEME Screening for the highest implied volatility means deliberately owning the market's jumpiest stocks. Big swings are the design, not a malfunction.
  • You pay 0.69% for the concept. Broad momentum funds (MTUM, SPMO, VFMO) run at a fraction of that, in the 0.12% to 0.15% range.
  • Launched in October 2025, so there is little live history to judge, and it lands in the lower half of its momentum peer group on our review.prnewswire.com
  • 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.
