Vanguard (VB) vs. State Street (SPSM) in a Small-Cap ETF Showdown

Vanguard's Vanguard Morningstar Small-Cap ETF (VB) and State Street's SPDR Portfolio S&P 600 Small Cap ETF (SPSM) are two popular options for investors seeking small-cap exposure. However, the two funds differ in their approach to diversification and selection of holdings.

VB boasts an extensive list of 1,357 holdings, offering investors broader diversification across a wide range of smaller companies. This extensive list aims to capture the small-firm effect, which suggests that smaller companies may outperform their larger counterparts over long investment horizons.

On the other hand, SPMG focuses on a more concentrated portfolio of 607 smaller companies. By narrowing its scope, SPMG seeks to provide investors with more concentrated exposure to a specific subset of small-cap stocks.

Both funds share the common goal of offering low-cost exposure to the small-cap market. However, the differing indexes they track—VB follows the CRSP U.S. Small Cap Index while SPMG tracks the S&P SmallCap 600 Index—result in distinct portfolios and risk profiles for investors.

Beta, a measure of price volatility relative to the S&P 500, is calculated using monthly returns over the available fund history, up to five years. This metric allows investors to gauge the relative risk of each ETF in comparison to the broader market.

The one-year return represents the total return over the trailing 12 months, providing a snapshot of each fund's performance during this period. Additionally, investors can consider the dividend yield, which is the trailing-12-month distribution yield, to assess the income potential offered by each ETF.

In conclusion, while both Vanguard's VB and State Street's SPMG offer small-cap exposure, their distinct approaches to diversification and selection of holdings set them apart. Investors should carefully consider these factors in order to determine which fund aligns best with their investment goals and risk tolerance.
