The Minimum-Volatility Phenomenon

Exchange-traded fund (ETF) flows can be a good indicator of investor sentiment.

So far this year, sentiment toward developed international equities has been tempered—of the top 30 flow gatherers, none are focused on this segment of the market.1

But in developed markets broadly, both the U.S. and internationally, there has been significant movement into funds that target minimum volatility.

With so much demand for holdings that exhibit lower historical volatility, what exactly are the characteristics of these stocks?

Let’s focus on the developed international universe, where the most compelling case for that market seems to come down to favorable valuations.

Watch the Price Tag

Basic finance theory tells us that a riskier basket of stocks should command a greater equity risk premium than a less volatile basket. Thus, it makes sense that a minimum volatility index would trade at a premium to the broader market.

We can test this theory by looking at the valuations of the MSCI EAFE Index and the MSCI EAFE Minimum Volatility (USD) Index. Going back to 2012, the valuation gap between the two indexes has oscillated between premium and discount. Oddly enough, investors have often gotten away with not paying a premium for lower-vol stocks.

Why? In part because those stocks have at times been discounted since they are over-weight in sectors with lower growth expectations, such as Utilities and Real Estate.

Today’s nearly 15% multiple premium for the min-vol index is near the most expensive valuation gap over the past five years. At these elevated valuations, investors modeling long-term returns based on this min-vol index need to dampen return expectations relative to the broader index.

Looking for Quality?

Min-vol indexes tend to have greater exposure to profitable companies, which explains in part the high correlation between the min-vol and quality factors. The loading to quality is evident from the table below that shows factor loadings across the Fama-French five-factor model. The trade-off for a 0.53 loading to quality is the -0.30 loading to value
