First Trust United Kingdom AlphaDEX Fund (FKU)

The First Trust United Kingdom AlphaDEX Fund (ticker FKU) applies a systematic, factor-based stock-selection approach to the British stock market, holding a focused portfolio of UK-listed companies identified by a computer algorithm that blends valuation and momentum signals.

The United Kingdom’s stock market is one of the world’s most mature and liquid, but it has underperformed global markets over the past 15 years. Slow economic growth, Brexit-related uncertainty, and the relative decline of traditional industries like banking and energy have weighed on returns. FKU is not a passive tracker that buys every major UK stock in market-cap proportions. Instead, it uses AlphaDEX—a quantitative selection system developed by Research Affiliates—to hunt for British stocks that appear cheap on traditional valuation measures while simultaneously showing upward momentum in price.

The algorithm ranks stocks on multiple dimensions: valuation (price relative to earnings, cash flow, book value), momentum (has the stock been rising?), profitability (do they make real earnings?), and quality (financial stability). It then selects stocks that score well on a blend of these signals, particularly favoring combinations where value and momentum both exist. The logic is straightforward: a stock that is both undervalued and rising is more likely to be a genuine opportunity than one that is simply cheap. By requiring momentum alongside value, the system tries to avoid value traps—stocks that are cheap because the business is deteriorating and will keep getting cheaper.

FKU typically holds 80 to 120 UK stocks across the full spectrum of the British market: the London Stock Exchange’s largest companies (often called FTSE 100 names) in sectors like banking and insurance, oil and gas, pharmaceuticals, consumer goods, mining, and industrials, alongside mid-sized and smaller-cap names. The fund applies sector limits so it is not overwhelmed by one industry, but within those boundaries the algorithm determines which specific companies get selected each quarter when the portfolio rebalances.

The largest holdings often include familiar multinationals like oil majors, banks, and mining groups. The algorithm is indifferent to whether a company is enormous or merely large; it cares about the valuation and momentum signals. This means FKU can tilt away from the market-cap-weighted index, potentially overweighting smaller components of the UK market that happen to signal well. This introduces tracking error relative to a passive UK index—sometimes a benefit, sometimes not, depending on whether the AlphaDEX factors are in or out of favor.

Because the system is rules-based and transparent, there is no hidden stock-picking judgment or market-timing discretion. First Trust follows the algorithm’s conclusions consistently. This brings discipline and lowers fees compared to a fund run by humans debating each stock, but it also means FKU has no special insight if the AlphaDEX logic breaks down in a particular market environment. The system is only as good as the factors it was designed around, which have worked well in some periods and disappointed in others.

FKU trades on US stock exchanges during normal trading hours, so investors can buy and sell shares at whatever price the market quotes. The fund’s expense ratio is moderate for an actively managed strategy, typically in the 0.4% to 0.7% range annually. Liquidity is generally adequate though tighter than in larger UK equity funds, particularly if trading large blocks. The fund does not distribute much income since UK companies have historically paid more modest dividends than US counterparts. Total return depends almost entirely on capital appreciation.

FKU’s holdings are priced in pound sterling, so investors face currency exposure. A weakening pound drags on returns for US-based investors (you get fewer dollars when you sell); a strengthening pound boosts them. The fund does not hedge this currency exposure, so it is a true UK equity bet, not a pound-neutral one. British stocks sit in the context of a mature, developed economy growing slowly and facing structural challenges: an aging population, underinvestment in infrastructure, and a weaker geopolitical position after Brexit. These are not problems FKU can overcome; they are the permanent backdrop investors inherit by owning British equities. A rules-based approach can find relatively better-valued stocks within that backdrop, but it cannot erase the backdrop itself.

FKU’s success depends on whether the combination of value and momentum signals actually identifies outperforming stocks in the UK market. This is an empirical claim, not guaranteed. Momentum-based strategies have delivered strong returns in certain periods and disappointing returns in others. Value investing itself lagged growth for much of the 2010s and 2020s, though periods of rotation toward value do occur. Investors comparing FKU to a simple, broad UK index fund should examine whether FKU’s factor bets have historically added value net of the fund’s fees.

To research FKU, read the fund’s fact sheet and prospectus on the First Trust website. Examine the current holdings to understand what kinds of UK companies the algorithm favors. Compare FKU’s total returns over three, five, and ten-year periods against a simple broad UK equity index fund to see whether the AlphaDEX overlay has paid for itself. Finally, understand the specific valuation and momentum metrics that AlphaDEX uses by consulting Research Affiliates’ publications on the system. This will help you grasp what FKU is betting on and whether you agree with that bet.
