Low-volatility exchange-traded funds are by now the market’s worst-kept secret. These ETFs, which own stocks that have moved less or are likely to move less than the broad market, have been among this year’s most popular investments. More than $16 billion has poured into the funds over the past year, causing so-called low-vol stocks to rise to record-high valuations. That may sound like a reason to sell, but running for the exits based on valuation defeats the purpose of owning low-volatility ETFs—to help stay invested in stocks through choppy markets.
