Investors looking to add U.S. equity exposure to their portfolios have a compelling choice between the State Street SPDR Portfolio S&P 1500 Composite Stock Market ETF (SPTM) and the Schwab U.S. Broad Market ETF (SCHB). While both funds aim to capture extensive sections of the U.S. market at a low cost, their underlying structures differ significantly, which can influence investment decisions.
The SPTM ETF targets 1,512 established firms by tracking the S&P Composite 1500 index, while SCHB broadens its reach to 2,410 companies through the Dow Jones U.S. Broad Stock Market Index. Both ETFs have identical expense ratios of 0.03%, making them among the most affordable options in the category. As of June 8, both funds reported a one-year return of 24.9%, showcasing their attractive performance during that period.
A closer look at their metrics reveals SPTM has assets under management (AUM) of $13.3 billion, whereas SCHB boasts a larger AUM of $42.4 billion. This increased size of SCHB contributes to greater liquidity, which may lead to tighter bid-ask spreads, a significant consideration for investors.
The beta values for both funds are nearly identical, with SPTM at 1.00 and SCHB at 1.01, indicating similar levels of market volatility relative to the S&P 500. However, SPTM exhibited a lower maximum drawdown of 24.1% over the past five years compared to SCHB’s 25.4%, suggesting SPTM may offer a slightly more stable investment experience.
In terms of sector allocations, both ETFs are heavily weighted towards technology, each at 37%. Other allocations vary slightly, with the financial services sector at 11% for both, and a slightly higher emphasis on consumer cyclical for SPTM at 10% compared to 9% for SCHB.
Top holdings also differ; SPTM lists Nvidia at 7.37%, Apple at 6.43%, and Microsoft at 4.44%. In contrast, SCHB features Nvidia at 6.99%, Apple at 6.33%, and Microsoft at 4.34%. This highlights SPTM’s more concentrated investment strategy, which may appeal to those seeking targeted exposure to leading firms.
Both funds deliver solid dividend yields, with SPTM yielding 1.04% compared to SCHB’s 1.01% over the trailing twelve months. For investors prioritizing income, SPTM might be a slightly better choice due to its higher payout.
Ultimately, the decision between SPTM and SCHB hinges on individual investment goals. For those leaning towards a focused investment in a smaller number of firms with lower volatility, SPTM appears favorable. Conversely, investors prioritizing broader exposure, including more small-cap stocks, may find SCHB appealing.
As always, potential investors should conduct thorough research and consider their long-term financial goals before making investment decisions. While these ETFs present excellent options for core U.S. equity exposure, selecting the right fund can depend on personal risk tolerance and investment strategy.
