Our read on VIOO

ETF.net Research

AVanguard'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

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

  1. 01Charges 0.07% a year against a peer-group median near 0.18% for funds built on the same small-cap index.
  2. 02Full replication, not sampling: it holds about 600 index constituents at their index weights, and it tracks the S&P SmallCap 600 very closely.
  3. 03Trading since 2010 and now a multi-billion-dollar fund, it ranks among the stronger implementations in its S&P 600 peer group.

Worth knowing

  1. 01Two rivals on the identical index undercut it: SPSM at 0.03% and IJR at 0.06%. Thin gaps, but gaps that compound.
  2. 02Moderately traded rather than the volume leader of the trio, so spreads carry more weight on big or rushed orders.
  3. 03This is undiluted small-cap equity. The mandate is to mirror that index, bumps included, not to smooth it out.
