What this means for investors
It's true that small-cap ETFs offer exposure to overlooked stocks that large investors often miss. Unfortunately, strategies that involve using them to invest in under-the-radar stocks have a fatal flaw. The best companies in the portfolio exit the small-cap index before they get a chance to produce big returns for investors.
Adding dividend payments slightly increases the returns investors can realize over the long term with these small-cap ETFs. That said, the returns have been more than a little disappointing compared to the benchmark S&P 500 index, which produced a 98.33% total return over the past five years.
Folks who bought the iShares SP Small-Cap 600 Growth ETF five years ago have realized a 33.43% return if we include the dividend payments they've received. The State Street SPDR S&P 600 Small Cap Growth ETF produced a slightly more attractive 33.97% return over the same time frame. If you're going to go with one of these ETFs, State Street's seems like the better option.
