There are plenty of broader market U.S. exchange traded funds with “small-cap” in their names, but different small-cap ETFs track different indices. That can mean, you guessed it, differing returns for different investors.
The Russell 2000 is the gold standard of small-cap indices and serves as the underlying index for the iShares Russell 2000 ETF (IWM) . With $23.1 billion in assets under management, IWM is the largest U.S. small-cap ETF.
However, the Russell 2000 and IWM face competition from a credible challenger: The S&P SmallCap 600. That index is benchmark for the iShares Core S&P Small-Cap ETF (IJR) and the SPDR S&P 600 Small Cap ETF (SLY) , which have $13.8 billion in combined assets under management.
“Since its launch, the S&P 600 has beaten the Russell 2000 in 12 of 19 years. The S&P benchmark is ahead for the five-, three- and one-year periods through the end of May, including leading by 20.2% to 16.8% over the latest 12 months,” reports Tom Lauricella for the Wall Street Journal.
Academics and index providers can debate which approach is better – the Russell 2000 or the S&P SmallCap 600 – and each has its merits. For example, a case can be made that the Russell 2000’s deeper bench is a more accurate, less biased gauge. On the other hand, the S&P SmallCap 600 has advantages of its own, including the exclusion of unprofitable companies, according to the Journal. [Investors Come Back to Small-Cap ETFs]
Recent weakness in small-caps has highlighted the importance of studying index differences. Over the past three months, IWM is down 3.9% while IJR and SLY are lower by 1.8%. The Vanguard Small-Cap ETF (VB) , which tracks the CRSP US Small Cap Index, is off 1% over the same time. With almost 1,460 holdings, VB has more than twice holding that IJR does, but the Vanguard fund is still holds far fewer stocks than does IWM. [Small-Cap ETF Riddle]
Recently, several of the top-performing small-cap ETFs have not been cap-weighted funds. Rather, some of the more durable small-cap funds have been dividend or low volatility plays.
For example, the WisdomTree SmallCap Dividend Fund (DES) is higher by 1% over the past 90 days. The nearly 680 companies in DES are pulled from the WisdomTree Dividend Index after the 300 largest market value firms are removed. The WisdomTree Dividend Index is the underlying index for the WisdomTree Total Dividend Fund (DTD) .
The WisdomTree SmallCap Dividend Index has a dividend yield of almost 3.3%. At a time when small-cap valuations are considered frothy, noteworthy is the 24.7 P/E ratio on DES, which while still above the S&P 500, is well below the P/E of almost 30 for IWM. [Small-Cap Dividend ETFs Winning]
