Long-term investors seeking comprehensive exposure to the U.S. stock market often turn to the State Street SPDR Portfolio S&P 1500 Composite Stock Market ETF (SPTM) and the iShares Core S&P Total U.S. Stock Market ETF (ITOT). Both ETFs provide a diversified approach, tracking similar underlying indexes that encompass large-, mid-, and small-cap companies within a single investment vehicle. Here’s a closer look at the key aspects of each fund to help investors choose the one that aligns best with their financial goals.
In terms of expenses, both SPTM and ITOT boast an attractive 0.03% expense ratio, categorizing them among the most cost-effective options for retail investors. As of May 15, 2026, the funds have reported comparable one-year returns, with SPTM at 28.40% and ITOT slightly higher at 28.45%. The dividend yield for SPTM stands at 1.09%, marginally exceeding ITOT’s 1.03%. Both funds maintain a similar beta, with SPTM at 1.01 and ITOT at 1.04, indicating they typically exhibit comparable levels of price volatility relative to the S&P 500.
Analyzing performance and risk metrics further illuminates the distinctions between the two. Over the past five years, SPTM experienced a maximum drawdown of 24.15%, while ITOT’s was slightly more pronounced at 25.35%. When assessing growth of a $1,000 investment over the same timeframe, SPTM shows a more favorable outcome, growing to $1,883 compared to ITOT’s $1,829.
Both ETFs share a similar sector allocation, with technology leading at 34%, followed by financial services (12%) and communication services (10% for ITOT and 11% for SPTM). When examining their stock holdings, ITOT includes 2,504 stocks, making it the broader option, while SPTM holds 1,511. Notable overlaps in top holdings feature tech giants like Nvidia, Apple, and Microsoft, reinforcing a shared investment strategy focused on leading market players.
For investors contemplating which ETF to choose, it’s essential to weigh the benefits of diversification against the specific features offered by each fund. ITOT’s inclusion of approximately 1,000 more stocks can be appealing for those seeking extensive market coverage. Despite this added diversification, both funds present similar risk and return profiles, indicating that the choice may not significantly impact performance.
Furthermore, ITOT’s greater assets under management, totaling $89 billion versus SPTM’s $13.5 billion, may provide enhanced liquidity. This may simplify large transactions without considerably influencing the ETF’s share price—a consideration for many investors, especially those executing substantial trades.
In summary, while both SPTM and ITOT deliver essential exposure to the U.S. stock market, investors must carefully consider their investment goals, preference for diversification, and the ease of trading when deciding between these two ETFs.
