RZGCInvesco S&P SmallCap 600 Revenue ETF

VIOOAVanguard S&P Small-Cap 600 ETF

In short

RZG Small-cap growth with no fence-sitters: RZG holds only the S&P 600 names that score strongest on growth, about 130 of them, weighted by growth score instead of size. A 2006-vintage purist in a cap-weighted world.

VIOO Vanguard's version of the S&P SmallCap 600: it owns all of the index's roughly 600 names at index weight, no sampling shortcuts, for 0.07% a year. That is well under half the typical fee among S&P 600 index funds, and it has been running since 2010.

Stated mandate

RZG The Fund is based on the S&P SmallCap 600 Revenue-Weighted Index and invests at least 90% of total assets in securities using a rules-based approach, with no company exceeding a 5% weighting.

VIOO The fund is a passively managed, full-replication ETF designed to follow the S&P SmallCap 600 Index, which represents small U.S. companies. It holds the index constituents in the same capitalization weights.

Why people hold it

  • RZG Pure means pure. S&P splits the 600 into growth and value with no overlap, so this owns the strongest growth scorers rather than a blend of both.invesco.comspglobal.com
  • Position sizes track growth scores, not market caps, so the stocks that rate highest on sales growth, earnings-to-price change and momentum carry the most weight.invesco.com
  • Rules-based, fully replicated and rebalanced once a year. No manager discretion, no constant reshuffling, and a live record going back to 2006.invesco.com
  • VIOO Charges 0.07% a year against a peer-group median near 0.18% for funds built on the same small-cap index.
  • Full replication, not sampling: it holds about 600 index constituents at their index weights, and it tracks the S&P SmallCap 600 very closely.
  • Trading since 2010 and now a multi-billion-dollar fund, it ranks among the stronger implementations in its S&P 600 peer group.

Worth knowing

  • RZG The 0.35% fee runs well above the typical S&P 600 tracker and far above core options like SPSM at 0.03% and IJR at 0.06%.
  • Thinly traded and modest in size, so spreads can run wider than on the core small-cap names, especially in fast markets.
  • About 130 stocks and one rebalance a year make for concentrated, style-tilted exposure that can wander a long way from the broad 600.invesco.com
  • VIOO Two rivals on the identical index undercut it: SPSM at 0.03% and IJR at 0.06%. Thin gaps, but gaps that compound.
  • Moderately traded rather than the volume leader of the trio, so spreads carry more weight on big or rushed orders.
  • This is undiluted small-cap equity. The mandate is to mirror that index, bumps included, not to smooth it out.
