First Trust Dorsey Wright Momentum & Low Volatility ETF (DVOL)

DVOL screens for stocks displaying momentum — recent price appreciation — but only among names that have not swung wildly. The result is equities gaining ground steadily, without the stomach-turning daily moves.

The methodology. Each rebalance period, typically quarterly, Dorsey Wright ranks all eligible stocks on recent momentum (three to twelve month price appreciation) and on realized volatility (the standard deviation of daily returns). A stock must clear both hurdles: positive momentum and low volatility relative to peers. Those that do make the cut; the rest drop out. The logic: if a stock is rising and doing so calmly, it may represent genuine strength. If it is rising but wildly volatile, that rise may be speculative and unsustainable.

What this actually buys. Roughly 100 to 150 large and mid-cap U.S. stocks, overwhelmingly from defensive sectors — utilities, consumer staples, healthcare, real estate, communication services. Industrials, technology, and discretionary consumer stocks rarely clear the volatility bar unless they happen to be the rare calm winners. The portfolio tilts heavily toward quality-of-earnings factors: stable revenues, predictable cash flows, modest leverage. Growth is sparse. The typical holding is a business that is quietly gaining share or benefiting from demographic trends, not one inflicting daily 5 percent swings on its holders.

The tension. Low-volatility strategies historically lag in broad bull markets, because the most volatile names — the high-beta growth stocks — often outperform. By adding momentum, DVOL tilts toward that segment of low-vol names that are rising, which should reduce the lag. But the momentum filter is still subordinate to the volatility ceiling, so DVOL will never own the highest-flying growth names. It trades upside for stability. That is the explicit bet.

Costs and structure. Expense ratio in the 0.50 to 0.75 percent range, reflecting the ongoing rebalancing. No leverage, no inverse mechanics — a plain ETF. Liquidity is good. Turnover varies with how much the momentum and volatility rankings shift each period; moderate to high is typical. Tax efficiency suffers in taxable accounts; tax-deferred retirement accounts avoid the drag.

The overestimation of safety. Many investors interpret “low volatility” as “downside protection” and assume DVOL provides a cushion in crashes. This is incorrect. A 20 to 30 percent market decline will still produce losses in DVOL, even if the daily swings are smaller on the way down. The volatility filter reduces the amplitude of moves, not the direction. A stock that typically moves two percent per day will trade smaller swings than one moving five percent daily, but both fall when the market falls. Investors expecting DVOL to be a hedge against equity declines will be disappointed.

When it works. In choppy, grinding markets where the most brutal volatility comes from a handful of mega-cap growth names. If technology is ripping and dragging the broad market higher, but with daily 3-5 percent swings, DVOL captures some of the gain while side-stepping the worst of the chop. In a steady bull market where winners move straight up, DVOL looks like an anchor. In a market where volatility is a drag — rising rates, geopolitical uncertainty, earnings misses — the calm discipline often pays.

When it fails. Across a strong bull market where growth names are serene and rising together (as in 2017), DVOL lags because it is still screened for low volatility, not growth. In a sharp crash, the filter provides no protection. In a period where the quietest stocks are the worst performers — a moment of widespread complacency — DVOL captures that underperformance without any upside to offset it.

The research task. Pull multiple years of trailing returns and volatility metrics. Compare DVOL to pure low-vol funds, pure momentum funds, and broad indices. Note which environments favor it (choppy markets, rising rates) and which penalize it (smooth rallies, rate cuts). The turnover rate matters enormously for tax planning. In taxable accounts, a 60 percent annual turnover can cut returns by 0.5 to 1 percent annually depending on cost basis and gain distribution. In IRAs, turnover is irrelevant.

The honest read. DVOL is not a defensive hedge. It is a systematic bet that combining momentum and low volatility identifies stocks with favorable risk-adjusted characteristics. Whether that bet works depends on market regime and time horizon. For a taxable, medium-term horizon, it requires careful tax planning. For a longer-term, tax-deferred account, it may offer useful risk reduction without sacrificing too much return.
