What Is IJT? iShares S&P Small-Cap 600 Growth ETF

Most small-cap growth indexes start from a universe defined only by size, which means they can select the fastest-growing companies from a pool that includes many with no earnings at all. The S&P SmallCap 600 applies an earnings requirement to the universe first. Growth characteristics are then measured within that filtered set. The order of operations is the whole story: companies are screened for profitability before they are screened for growth.

What survives that process is not the archetype of small-cap growth investing. Rather than pre-revenue biotechnology and unprofitable software, the fund fills up with engineering and construction firms, specialist manufacturers, commercial services businesses and profitable niche technology companies. In October 2026 the top ten includes ESCO Technologies, an industrial products manufacturer, Zurn Elkay Water Solutions, which makes water management products, and Armstrong World Industries, a ceiling and wall systems maker. Argan and Everus Construction Group, two construction firms in the August top ten, have since dropped below it.

The healthcare weight of 16% is where the gate shows most clearly. Protagonist Therapeutics at 1.1% and TG Therapeutics at 1.0% are now the top-ten healthcare names, replacing Krystal Biotech and Alkermes from August. Biotechnology companies only reach this index by clearing the earnings requirement, which is why the ones here have revenue rather than only a pipeline.

The August 2026 list included BlackRock Cash Funds Treasury at 1.2%, which is not a company. It is a cash management vehicle used for settlement and collateral, common in iShares funds and not a portfolio position in any meaningful sense. The October list shows ten operating companies, running from FormFactor at 1.4% down to Armstrong World Industries at 0.8%.

Those weights are larger than in a full small-cap index but still modest. FormFactor makes semiconductor test equipment, Viasat operates satellite communications, Ryman Hospitality Properties owns large convention hotels, Madison Square Garden Sports owns the Knicks and Rangers, and StoneX is a financial services and brokerage firm. It is a heterogeneous list, which is what a growth screen applied to a profitable small-cap universe produces: no dominant theme, just companies whose earnings and sales are expanding.

There is a size point buried in the list as well. The S&P SmallCap 600 sits below the mid-cap range, and its growth half is drawn from companies that are profitable but still small. Set against a mid-cap growth fund, these businesses are earlier in their commercial life and more exposed to a single product line or a small number of customers. Set against a size-only small-cap index, they are further along, because the earnings requirement removes companies still funding themselves through capital raises.

At 0.18% the fund costs more than a broad small-cap index fund but sits at the cheaper end of style-specific products. The premium buys the index construction, not management judgment. The 0.78% yield is the lowest sort of figure you will see outside a pure growth fund, since growth companies of this size reinvest rather than distribute.

IJT is the wrong tool for someone wanting exposure to speculative small-cap growth, because the earnings requirement excludes exactly that segment. It is also the wrong tool for anyone who assumes a growth label implies a technology-dominated portfolio, given industrials carry as much weight as technology here. And it duplicates a large part of any broad small-cap holding, since the growth half of an index is drawn from the same companies a total small-cap fund already owns.

Turnover is the other cost worth noting. Companies move between the growth and value halves of the index as their characteristics change, and they leave the parent index entirely when they grow too large or stop meeting the earnings requirement. That produces more trading than a broad market fund, which shows up in the fund's internal transaction costs rather than in the stated expense ratio. It is a general feature of style indexes rather than a flaw specific to this one.

Recent trading shows the volatility that comes with the size bracket. The fund's price rose 12.2% in 2026 through 2026-10-16 and 14.1% over twelve months, but fell 7.8% over the last three months, and Yahoo lists its 3-year beta at 1.08. Assets declined from $8.2B in August to $7.6B in October, a drop that reflects both the price decline and possible outflows; the data does not separate the two.

There are three common ways to get IJT exposure. Buy shares (or fractional shares) of IJT directly at any major broker that lists it. Hold it as a core position and layer more concentrated ideas on top. Or build it into a thematic portfolio in Walnut, so IJT sits alongside other holdings that express the same thesis, with target weights you can rebalance toward. IJT trades like a stock during market hours, so you buy it the same way you would any listed share.
