SIZEAiShares MSCI USA Size Factor ETF

XSMOCInvesco S&P SmallCap Momentum ETF

In short

SIZE The size factor without leaving the large-cap pool: SIZE holds roughly 500 US stocks and leans toward the smaller names in that universe, spreading weight away from the mega-cap giants. An iShares factor original from 2013.

XSMO Momentum, but only among small caps that actually make money. XSMO rides the strongest performers in the S&P SmallCap 600, weighted by momentum score and reshuffled twice a year, for 0.35% with no fee waiver in place.

Stated mandate

SIZE The fund seeks to track an index of U.S. stocks that have smaller market capitalizations relative to their peers.

XSMO The fund is based on the S&P Smallcap 600 Momentum Index and invests at least 90% of total assets in the index's component securities.

Why people hold it

  • SIZE Charges 0.15%, roughly half the typical fee among US factor ETFs.
  • Tracks the MSCI USA Low Size Index tightly, one of the closer index implementations in its peer group.
  • Roughly 500 holdings, so no single name dominates the way it does in a cap-weighted US index.
  • Running since 2013, one of the original iShares single-factor funds rather than a recent launch.ishares.com
  • XSMO S&P demands positive earnings in the latest quarter and the trailing four combined before a stock joins the SmallCap 600, so momentum is drawn from profitable companies.spglobal.com
  • Weighting is float-adjusted market cap times momentum score, so the strongest trends carry the heaviest weight instead of every winner getting an equal slice.spglobal.com
  • Listed in 2005 and now a multi-billion-dollar fund, it has run through several full market cycles rather than one hot stretch.
  • Plain mandate: at least 90% of assets in the index's own components, no discretionary side bets.invesco.com

Worth knowing

  • SIZE Thinly traded next to headline index funds, so bid-ask spreads can run wider and bigger orders need more care.
  • This is a tilt, not a small-cap fund: the index draws from US large and mid caps and favors the smaller end of that pool.
  • A mid-sized fund by category standards, not one of the asset-gathering giants. Pays quarterly.
  • XSMO About 110 names, tilted toward the hottest movers, so the ride is bumpier than a broad small-cap index.spglobal.com
  • The index reshuffles in March and September, so names whose trend breaks mid-period stay put until the next rebalance.spglobal.com
  • At 0.35% with no fee waiver, it sits near the category median, above plainer factor options like SIZE at 0.15% or MGV at 0.05%.

SIZE vs XSMO Holdings

How we measure overlap

Each holding counts at its smaller weight in the two funds, summed over the full Holdings. Sector, country and asset class use the same rule on each fund’s split. Cash, FX and derivative lines stay out of the counts. Two bond funds get no overlap figure.
