iShares Morningstar Small-Cap ETF casts a wide net with 1,539 holdings, offering exposure across industrials (19%), technology (16%), and financial services (15%). Its largest positions — Ciena (NYSE:CIEN), Coherent (NYSE:COHR), and Rocket Lab (NASDAQ:RKLB) — each account for less than 1% of assets, reflecting a very diversified approach. The fund has a track record of 21.5 years, and no notable quirks or specialized strategies.
iShares Core SP Small-Cap ETF, by contrast, holds 635 names, with the biggest sector weights in financial services, industrials, and technology. Its top holdings include Hecla Mining (NYSE:HL), Spx Technologies (NYSE:SPXC), and Dycom Industries (NYSE:DY) all with similarly small weightings. Both funds stick closely to mainstream U.S. small-cap exposure, but IJR’s larger size and higher yield may appeal to those prioritizing income and liquidity.

IJR and ISCB both offer access to U.S. small-cap stocks, but they take notably different approaches to capturing this segment of the market.
IJR manages a massive $88 billion in assets with daily trading volume averaging over 6 million shares, making it one of the most liquid small-cap ETFs available. ISCB, by contrast, holds just $257 million in assets with far lighter trading volume. For investors who prioritize easy entry and exit or plan to make large trades, IJR’s liquidity advantage is substantial.
However, ISCB brings compelling benefits of its own. It charges just 0.04% compared to IJR’s 0.06% expense ratio, and its 1,539 holdings provide significantly broader diversification across the small-cap universe. ISCB’s wider net means reduced concentration risk, though both funds maintain similar sector allocations across industrials, financials, and technology.
Investors seeking maximum liquidity and the confidence that comes with massive fund size should favor IJR. Those prioritizing rock-bottom costs and the widest possible small-cap diversification might prefer ISCB, provided they’re comfortable with lower trading volumes.
