In the landscape of exchange-traded funds (ETFs), the State Street SPDR Portfolio S&P 1500 Composite Stock Market ETF (SPTM) and the Schwab U.S. Broad Market ETF (SCHB) emerge as prominent vehicles designed to replicate the performance of the expansive U.S. stock market with minimal costs. Each ETF offers an attractive expense ratio of just 0.03%, positioning them as potential core holdings for investors looking to diversify their portfolios effectively.
A comparative analysis reveals that both SPTM and SCHB yield similar returns and expense structures. As of January 25, 2026, SPTM reported a one-year return of 12.91% while SCHB followed closely behind with a return of 12.80%. The dividends from both funds are nearly identical, with SPTM at 1.13% and SCHB at 1.11%. Furthermore, both funds exhibit comparable volatility, with beta values of 1.02 for SPTM and 1.05 for SCHB—indicating similar price movements relative to the S&P 500.
In terms of assets under management (AUM), SCHB holds a significant advantage, boasting $38 billion compared to SPTM’s $12 billion. This larger asset base not only signifies popularity among investors but also enhances liquidity, permitting large-scale transactions without substantially influencing the ETF’s market price. Moreover, SCHB contains 2,401 stocks in its portfolio, whereas SPTM tracks approximately 1,510 stocks. This difference in the number of holdings provides SCHB with a broader market exposure, which could appeal to investors aiming for a more diversified investment approach.
Both ETFs share nearly identical sector allocations, with SCHB allocating 33% to technology, 13% to financial services, and 11% to consumer cyclical sectors. Their leading holdings include industry giants Nvidia, Apple, and Microsoft, which account for approximately 18.35% of SCHB’s portfolio and 19.79% of SPTM’s.
When examining performance metrics, both ETFs display comparable maximum drawdowns over the past five years, with SPTM at -24.15% and SCHB slightly higher at -25.40%. The growth of a $1,000 investment over five years shows SPTM performing marginally better at $1,765 compared to SCHB’s $1,700, although these differences are relatively negligible given the overall market conditions.
Despite their close resemblance in numerous aspects, potential investors may find the choice between SPTM and SCHB hinging on their need for higher liquidity and broader market exposure. With its larger asset pool and a greater number of holdings, SCHB may be more appealing for those prioritizing comprehensive diversification in their investment strategies. Both ETFs, however, represent viable options for investors seeking cost-effective exposure to the U.S. stock market.
