VIOOAVanguard S&P Small-Cap 600 ETF

In short

SLYG Live since 2000, SLYG splits the S&P SmallCap 600 in two and keeps the growth half: roughly 400 small companies screened on growth and momentum. An old, plain wrapper around a sharp style tilt.

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

SLYG The fund seeks to deliver, before fees and expenses, total returns that generally correspond to the S&P SmallCap 600 Growth Index.

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

SLYG Running since 2000 and now a multi-billion-dollar fund: one of the original ways to own the growth half of the S&P SmallCap 600.
Cheap for a style fund at 0.15%, under the 0.18% median of its S&P 600 peer group, and the portfolio hews closely to its index rather than drifting.
Roughly 400 stocks, cash paid quarterly, and a matching value sibling (SLYV) for the other half of the same index family.

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

SLYG Vanguard's VIOG tracks the same declared index for 0.10%. Same shopping list, lower sticker.
Growth is half the S&P 600 by construction, so it behaves differently from full-index funds like SPSM and IJR, and sits at the jumpier end of small caps.
Moderately traded rather than a firehose. The broad S&P 600 funds see heavier volume, which can show up in spreads on big or hurried orders.

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.
