VIOGBVanguard S&P Small-Cap 600 Growth ETF

VIOOAVanguard S&P Small-Cap 600 ETF

In short

VIOG Vanguard's growth slice of the S&P SmallCap 600, running since 2010 at 0.10% a year. Only one other ETF tracks the same index, and it charges more.

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

VIOG The fund seeks to track the performance of the S&P SmallCap 600 Growth Index, which represents small U.S. growth companies.

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

VIOG At 0.10%, it undercuts the only other fund on the same index (SLYG at 0.15%) and lands well under its peer group's 0.18% median fee.
One published index, one style slice, no manager discretion. It follows the S&P SmallCap 600 Growth Index closely and stands in the upper half of its S&P 600 peer group.
Live since 2010, with a record across several market cycles, and it spreads across roughly 300 small-cap growth names instead of a short list.
A multi-billion-dollar fund from Vanguard, and it pays out quarterly.

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

VIOG Thinly traded next to the S&P 600's core giants, so the bid-ask spread is a bigger slice of your real cost than the expense ratio suggests.
Style slicing carries a surcharge: whole-index cousins like SPSM (0.03%) and VIOO (0.07%) cost less than owning just the growth half.
Narrow by design. The growth half of a small-cap index moves more sharply than a broad US stock fund.

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.
