Xtrackers FTSE Developed ex US Multifactor ETF (DEEF)

The Xtrackers FTSE Developed ex US Multifactor ETF (NASDAQ: DEEF) is an international stock fund that takes a mathematical approach to stock selection. Rather than simply buying all the large companies in developed Europe, Japan, Canada, and Australia, the fund selects companies that score highest on multiple financial factors — quality of earnings, valuation relative to fundamentals, momentum, and other measures. The result is a concentrated, tilted version of developed international markets rather than a vanilla index.

International investing presents a choice that many U.S. investors have not fully considered: why own a foreign stock at all if the economy and earnings are denominated in another currency, the regulatory environment is uncertain, and the timezones make trading inconvenient? The answer is diversification. A portfolio of only U.S. stocks is implicitly betting that American companies will outperform their global peers indefinitely — a wager that felt true from 2010 to 2024 but has not always held, and may not hold forever. Adding developed-market exposures elsewhere hedges that concentration and potentially smooths returns by capturing gains in regions where valuations are lower and the growth story less crowded.

The FTSE Developed ex US index that DEEF builds on includes large and mid-cap companies across Europe, Japan, Canada, and Australia. It excludes the United States — the “ex US” in the name — and also excludes emerging markets. This leaves investors with the most established, liquid, transparent markets outside America. The index itself is broad and neutral, weighting companies by market capitalization. DEEF goes further, applying a multifactor screen that seeks to concentrate the portfolio in the stocks most likely to outperform based on historical patterns.

Multifactor strategies rest on academic research showing that stocks with certain characteristics — cheap valuations, high profitability, recent price momentum, low volatility — have delivered above-market returns over long periods. No single factor works all the time; value beats growth for years, then growth crushes value; momentum works until it reverses sharply. A multifactor approach mixes these bets, hoping that combining factors smooths out the periods when any single one is in a drawdown. DEEF targets companies scoring high on quality, value, and momentum simultaneously, plus a dividend tilt that favors companies with steady payouts.

The result is a portfolio of roughly 400 to 500 companies, weighted more heavily toward the highest-scoring names and lighter toward lower-scoring ones. A Japanese pharmaceutical company with high earnings quality, a cheap valuation relative to its growth prospects, and steady momentum might be a 3% position in DEEF, while a European oil giant with worse metrics might be 0.5%. The fund is rebalanced quarterly, as new data updates the factor scores and positions are shuffled to reflect changing factor rankings.

An investor buying DEEF is making several bets at once. First, the bet on developed markets ex-US performing reasonably well — a bet on Europe not sliding into stagnation, on Japan’s economy continuing to reform and grow, on Canada and Australia remaining stable. Second, the bet that the specific multifactor screen — quality, value, momentum, and dividend — identifies outperformers more often than chance would suggest. Third, the bet that concentrating the portfolio around the highest-scoring names — making the portfolio less diversified than a cap-weighted index — will amplify returns over time rather than creating uncompensated risk.

The costs of this approach are material. The fund’s expense ratio is roughly 0.30% to 0.40%, higher than a plain-vanilla developed-markets index fund, which might charge 0.10% to 0.15%. The factor-tilted construction creates more trading and rebalancing turnover than a cap-weighted index, which can drag on returns through transaction costs and tax drag. Over five years, an investor might find DEEF’s returns closely tracking the underlying developed-markets index, with the multifactor tilt providing a slight boost or bust depending on whether the selected factors worked.

The timing matters enormously. In periods when value stocks outperform growth and momentum favors stocks with steady fundamentals, DEEF’s screen does well and the fund beats its benchmark. In periods when expensive, fast-growing tech stocks dominate international markets, the factor screen becomes a drag; DEEF owns neither the expensive companies that are driving returns nor the cheap commodity plays that everyone else has abandoned. An investor committing to DEEF should be comfortable with the possibility of 3-5 year stretches of underperformance relative to a cap-weighted developed-markets benchmark, on the belief that the factors will eventually work and the outperformance will compensate.

For a U.S.-based investor, DEEF also introduces currency risk. Japanese yen, euros, Canadian dollars, and Australian dollars fluctuate against the U.S. dollar. When the dollar weakens, international stocks are worth more in dollar terms, providing a tailwind. When the dollar strengthens, the same stocks are worth less in dollar terms, becoming a headwind. An investor could hedge that currency risk away using forwards and currency contracts, but DEEF does not — it leaves the full exposure. A strong dollar environment is a headwind for returns; a weak dollar is a tailwind.

The fund is most suitable for investors who have already established a U.S. equity core and are comfortable with the case that international diversification adds value despite the currency exposure and the timing risk. It is less suitable for someone building their first equity position or someone uncomfortable with factor-tilted strategies or currency hedging. DEEF’s strongest use case is as a satellite position — say, 10% to 25% of an international allocation — held with conviction that the multifactor approach will work over years, not expected to beat the market decisively in any single year.

Prospective owners should review the fund’s holdings, the current factor tilts, and the breakdown by country and sector. The quarterly rebalancing results, published by the fund, show how the screen is moving; widening the allocation to value factors indicates the screen is leaning heavily on cheap valuations, while a tilt to quality indicates a preference for high-return-on-equity companies. Understanding those tilts helps an investor understand what market environment might be a headwind or tailwind for the strategy over the next several quarters.
