Single Factor Focus: Ranking The Top 'Low Volatility' ETFs

August 01, 2016

Low-volatility ETFs are in vogue. That's clear to see with just a cursory glance at the fund flows page. Year-to-date, the iShares Edge MSCI Min Vol USA ETF (USMV | A-76) picked up $6.7 billion from investors, putting it at No. 3 on the inflows leader list, according to FactSet data.

But it's not just USMV. There are 11 single-factor, low-volatility products on the market, and in total they've seen inflows of $14.1 billion so far this year.

It's not necessarily surprising to see the strong interest in these products. They've broadly outperformed their vanilla, market-cap-weighted counterparts in 2016. Moreover, academic research suggests low-volatility is one of the six factors that have delivered long-term outperformance.

There's no guarantee that low-volatility ETFs will continue to outperform going forward; and in fact, there's been concern among some analysts that low-vol stocks have become overvalued. Nevertheless, for investors wanting to get exposure to the low-volatility factor, it's never been easier.

Here we take a look at the different ETF options available to invest in.

US-Focused Low-Vol ETFs

There's six low-volatility ETFs that target U.S. equities. The aforementioned USMV is the most popular, with more than $15 billion in assets. It targets a broad swath of the U.S. stock market, including large caps and midcaps. USMV follows an index "that screens for low volatility stocks, takes into account the correlations among them, and then generates an optimized portfolio with guardrails in place to limit sector concentrations."

The PowerShares S&P 500 Low Volatility Portfolio (SPLV | A-70), with $8 billion in assets, takes a more straightforward approach by simply holding the 100 S&P 500 stocks that exhibited the lowest daily volatility over the past year.

Another low-vol ETF heavy on the large-caps is the SPDR Russell 1000 Low Volatility ETF (LGLV | B-76). The fund, which failed to attract much in the way of assets in its 3 1/2 years on the market, currently only has AUM of $77 million. LGLV tracks the 200 least-volatile stocks in the Russell 1000, optimized "to neutralize exposure to other factors, such as beta and momentum."



The other three low-volatility U.S. ETFs currently available focus on either midcaps or small-caps. The PowerShares S&P MidCap Low Volatility Portfolio (XMLV | A-54), one of the sister funds to SPLV, tracks the 80 least-volatile stocks in the S&P MidCap 400 Index. The other sister fund, the PowerShares S&P SmallCap Low Volatility Portfolio (XSLV | A-48), tracks the 120 least volatile stocks from the S&P SmallCap 600 Index.
