On CAPS, 90.5% of the 147 members who have rated Vanguard Small-Cap believe the ETF will outperform the S&P 500 going forward. These bulls include Zen1212 and acegdl007.

Last year, Zen1212 succinctly summed up the investment case: "If you're looking for a way to get into small caps but are concerned about the risks and volatility of small cap stocks, this is a good way to diversify a portfolio and spread the risk out."

Vanguard Small-Cap, in particular, sports a low expense ratio of just 0.17%. That's cheaper than that of other small-cap ETF plays like iShares Russell 2000 (0.26%) and iShares S&P Small-Cap 600 (0.20%).

CAPS member acegdl007 expands on the outperform argument:

Vanguard started offering this about 6 years ago as an ETF version of its Small Cap mutual fund. ... Vanguard has a great reputation for offering attractive funds and ETF's with some of the lowest management costs and fees. This is a great ETF/fund to include in a 401k portfolio that will add a comfortable dose of risk with potential for good growth in the long term.
