Small-Cap ETF Face-Off: Comparing SCHA and ISCB Sector Tilts

The selection between the Schwab U.S. Small-Cap ETF (SCHA) and the iShares Morningstar Small-Cap ETF (ISCB) comes down to a trade-off between institutional scale and sector-specific conviction. Both vehicles provide broad exposure to the U.S. small-cap equity market with an identical expense ratio of 0.04%. While both funds aim to capture the small-cap premium, they utilize different weighting strategies. SCHA is the larger of the two, offering superior liquidity and trading volume, which typically appeals to institutional investors or those managing larger positions. Sector allocation is the primary differentiator. SCHA maintains a stronger tilt toward Technology at 18%, followed by Financial Services and Industrials at 16% each. In contrast, ISCB leans more heavily into Industrials (18%), Financial Services (16%), and Healthcare (14%). ISCB also offers a marginally higher dividend yield. In terms of diversification, SCHA holds 1,729 stocks, while ISCB holds 1,554. Common holdings include Lumentum Holdings Inc. and Revolution Medicines Inc., though SCHA also features Sandisk Corp among its top positions, while ISCB includes Albemarle Corp. Long-term performance has remained closely aligned, with only a $41 difference on a $1,000 investment over five years. The decision for investors rests on whether they seek to avoid further technology concentration or prefer the defensive characteristics of healthcare.
