First Trust Utilities AlphaDEX Fund (FXU)

FXU was launched in the mid-2000s as part of First Trust’s growing AlphaDEX family — rule-based funds that apply quantitative screening to traditional stock-market sectors. From inception, it has screened utilities for value and momentum, carving out a concentrated portfolio that differs from the cap-weighted utility indices most investors own.

The AlphaDEX approach arrives in utilities

When the AlphaDEX platform was developed, First Trust applied it across major sectors including industrials, technology, energy, and utilities. The utilities version was designed to answer a straightforward question: within the regulated utility sector, which stocks are cheaply valued and gaining momentum?

The sector itself is defined by companies that distribute electricity, natural gas, or water — regulated monopolies in most cases — and a smaller set of energy-infrastructure firms that own transmission lines, renewable generation, or similar assets. Utilities tend to be dividend-paying, stable-earnings businesses that attract conservative investors and retirees seeking income. They are among the least volatile sectors in the stock market.

FXU takes that stable sector and applies a quantitative lens that screens for relative value and positive momentum. The result is a concentrated portfolio of 40–80 utility names that the algorithm judges to be attractively priced and gaining upward traction relative to their peers.

From launch through the dividend boom

FXU’s inception in the mid-2000s put it on the market before the 2008 financial crisis. Through that period, utilities proved their defensive reputation — stocks that stayed relatively stable while growth sectors crashed. As the recovery unfolded, utilities became a popular holding for investors fleeing low interest rates and seeking yield, particularly after the Federal Reserve kept rates near zero throughout the 2010s.

The rising interest-rate environment of 2022 and beyond created headwinds for utilities — when bond yields climb, the relative attractiveness of utility dividends falls — yet the sector remains a staple of conservative and income-focused portfolios. FXU, with its value and momentum tilt, captures the sector but with a bias toward names that appear cheaper and are showing relative strength.

Over its history, FXU has competed against broader utility ETFs and specialized dividend-focused funds. Its value-and-momentum screening has led to periods of outperformance (when those factors favored utilities) and underperformance (when growth or mega-cap utilities outpaced the rest).

Composition and sector characteristics

Utilities typically comprise regulated electric and gas distributors, diversified utility conglomerates, and independent power producers. Examples include large-cap names like Duke Energy and Exelon, mid-cap companies like smaller regional utilities, and specialized infrastructure firms focused on transmission or renewable generation.

FXU tilts toward mid-cap and smaller large-cap utilities, typically holding 40–80 stocks. The AlphaDEX screen removes mega-cap utility leaders in favor of names that score well on relative valuation and momentum metrics. This means FXU will often underweight the largest utility franchises and overweight smaller, faster-growing utilities or infrastructure firms.

The fund rebalances quarterly, modifying positions as the quantitative screen updates its rankings. Turnover is moderate, higher than a passive cap-weighted utility index but disciplined by the screen’s fixed rules.

How utilities have changed since FXU’s launch

The utility sector in the mid-2000s was primarily about regulated distribution — local monopolies with stable, predictable cash flows. Today, the sector has broadened to include renewable energy generation, battery storage, and smart-grid infrastructure. Many traditional utilities are transitioning toward cleaner generation and are investing heavily in transmission upgrades.

This shift affects FXU indirectly. The screens the fund applies are purely mechanical — valuation and momentum metrics — so they do not explicitly favor utilities moving into renewables. However, a utility transitioning away from fossil fuels might experience positive momentum (if investors are rotating into the trend) or negative momentum (if its traditional earnings are seen as at risk before the renewable buildout yields returns). The fund captures those transitions through its factor lenses but does not tilt toward them by design.

Costs and practical structure

FXU trades on NASDAQ with a standard expense ratio typical of active ETFs — usually in the 0.60–0.70 percent range. The bid-ask spread is generally tight. The fund is considerably smaller and less widely held than a mega-cap utility ETF, which can mean slightly wider spreads in off-peak hours.

The tension in utilities factor investing

Utilities are perhaps the most stable sector in equities — earnings are regulated, growth is predictable, and volatility is low. The value-and-momentum factors that FXU chases are often most potent in volatile, fast-growing sectors where cheap stocks can rapidly rerate higher if sentiment shifts.

In utilities, a “cheap” utility is often cheap for structural reasons — it faces transition challenges, operates in a struggling region, or has aging infrastructure. A “momentum” utility might be gaining share because of renewable investment trends or because a major project is coming online. These patterns are real, but they operate in a narrower band of volatility than in growth sectors.

As a result, the outperformance of FXU relative to a broad utility index tends to be modest and inconsistent. Years when value and momentum factor strongly favor utilities will see FXU shine; years when cap-weighted mega-cap utilities dominate (which is frequent, because the largest utilities are enormous), FXU will lag.

How to research FXU

Start with First Trust’s fact sheet and prospectus, which detail the AlphaDEX screening process and the fund’s current holdings. Compare FXU’s historical performance to a standard utilities ETF — either a cap-weighted fund like the Vanguard Utilities ETF or a dividend-focused alternative — to understand how often and by how much the factor tilt has added or subtracted value.

Review the specific holdings at different time periods to see how the screen behaves when interest rates are rising (a headwind for utilities) versus when rates are stable or falling. Monitor whether the utility sector’s transition toward renewables is helping or hurting FXU’s momentum scores.

For investors in the utilities sector, the key question is whether the value-and-momentum tilt will outperform a simpler, cap-weighted approach over their time horizon. Utilities are inherently conservative; applying factor tilts to them is a more sophisticated bet that assumes those factors will continue to be rewarded even in a slow-growth, dividend-focused sector.
