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

Vanguard Morningstar Small-Cap ETF (NYSEMKT:VB) offers significantly broader diversification across 1,357 holdings, while State Street SPDR Portfolio S&P 600 Small Cap ETF (NYSEMKT:SPSM) focuses on a more concentrated selection of 607 smaller companies.

Small-cap ETFs offer growth potential by capturing the "small-firm effect," in which smaller companies may outperform larger peers over long investment horizons. While both of these funds aim for low-cost exposure, they track different indexes -- the CRSP U.S. Small Cap Index versus the S&P SmallCap 600 Index -- resulting in distinct portfolios and risk profiles.

Which looks like the better buy

First things first -- I don't think prospective investors can really "go wrong" with either one of these two small-cap ETFs. VB has delivered annualized total returns of 10.3% since 2013, while SPSM has generated similar returns of 9.6% over the same time.

However, despite stronger returns over the last 13 years, I might lean toward buying SPSM for a couple of reasons. First, its 1.56% dividend yield is reasonably higher than VB's at 1.28%, and SPSM has delivered stronger dividend growth over both the last five and ten years.

Furthermore, SPSM filters entrants to its small-cap portfolio by profitability, which helps make it a steadier, stronger portfolio. VB, meanwhile, doesn't have this profitability filter, making it slightly more volatile and helping explain why it may pay a small dividend with more speculative, growth-style holdings.

Ultimately, they are both fine selections for gaining small-cap exposure, but I'd lean ever so slightly toward SPSM for its higher yield and stronger profitability, especially since both maintain the same expense ratio.
