IJRAiShares Core S&P Small-Cap ETF

VIOOAVanguard S&P Small-Cap 600 ETF

In short

IJR Small caps, but only the ones making money. IJR tracks the S&P SmallCap 600, an index that screens for positive earnings before a stock gets in, and it has been the big, heavily traded way to own that basket since 2000.

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

IJR The fund seeks to track an index representing small-capitalization U.S. equities.

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

IJR The index runs a profitability screen: no positive earnings, no entry. The money-losing tail of the small-cap market never reaches the portfolio.spglobal.com
0.06% a year, against a 0.18% median for funds wrapping this same index. One of the strongest overall implementations in that peer group.
Trading since 2000 and now one of the largest, most actively traded S&P 600 funds available.
Roughly 700 US small-cap positions, cash paid 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

IJR Cheaper twins exist on the identical index: SPSM charges 0.03%, VIOO 0.07%. On headline fee alone, IJR is not the low bid.
Small-cap stocks move more sharply than large caps, and this is straight index exposure with no hedge or cushion.ishares.com
The earnings screen cuts both ways. When speculative, unprofitable small caps run, this index simply isn't holding them.spglobal.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.
