Düsseldorf. For the past few years, the global stock market narrative has been dominated by a single, powerful force: the artificial intelligence (AI) boom. While this surge in technological innovation has driven unprecedented gains for major indices, it has created a profound and, for many risk-averse investors, increasingly uncomfortable side effect: a structural imbalance in global equity portfolios.
As concentration risk reaches historic highs, market analysts are increasingly questioning whether the traditional "passive" approach—exemplified by the MSCI World—is still the most prudent path for the long-term investor. With the technology sector now commanding a disproportionate share of global indices, a shift toward more diversified, factor-based, and equal-weighted investment strategies is gaining traction.
The Problem with Concentration: A Market Out of Balance
The primary concern for modern investors is the extreme concentration within global benchmarks. In the MSCI World, the two technology-centric sectors—Information Technology and Communication Services—now account for nearly 40 percent of the total index weight. Furthermore, the geographical concentration is even more striking, with US-listed equities comprising nearly 72 percent of the index.
This creates a scenario where the performance of a supposedly "global" portfolio is tethered almost entirely to the fortunes of a handful of US-based mega-cap companies. The market’s reliance on the "Magnificent Seven" (Alphabet, Amazon, Apple, Meta, Microsoft, Nvidia, and Tesla) has turned the MSCI World into a high-beta bet on tech innovation. When these stocks rally, the index soars; however, when the sector cools, the entire index suffers, regardless of the health of companies in other industries or geographies.
To address this, the Handelsblatt partnered with the data comparison platform ExtraETF to identify exchange-traded funds (ETFs) that offer a more balanced, diversified alternative to the traditional market-capitalization-weighted approach.
Chronology of the Shift: From Tech Dominance to Factor Diversification
The recent volatility in tech-heavy indices has sparked a notable rotation in investor sentiment. While 2023 and 2024 were characterized by a singular focus on AI-driven growth, the start of 2025 marked a shift.
- 2023–2024: The AI rally was in full swing. Investors flocked to market-cap-weighted indices, driving the MSCI World to double-digit gains. During this period, alternative strategies—such as equal-weighted or dividend-focused ETFs—often underperformed because they lacked the explosive growth of the semiconductor and software giants.
- Early 2025: The market began to show signs of fatigue. The "Magnificent Seven" faced increased scrutiny regarding valuation sustainability. Simultaneously, the US dollar began a significant decline, losing more than 10 percent against the Euro. This created a dual headwind for European investors in US-heavy funds: a softening of tech prices compounded by currency losses.
- Late 2025–2026: Alternative strategies began to prove their worth. Funds that diversified away from US tech and focused on quality, value, or geographic spread started to outperform the MSCI World, capturing the gains of a broader economic recovery rather than relying on a single theme.
Case Study 1: The L&G Gerd Kommer Multifactor Equity ETF
Developed by the renowned asset manager Gerd Kommer in collaboration with Legal & General Investment Management (LGIM), the L&G Gerd Kommer Multifactor Equity UCITS ETF (ISIN: IE0001UQQ933) represents a fundamental departure from the status quo.
A Macro-Economic Approach
Unlike the MSCI World, which weighs stocks strictly by market capitalization, the Kommer ETF utilizes a dual-weighting methodology. Country weights are determined 50 percent by market capitalization and 50 percent by Gross Domestic Product (GDP). This ensures that emerging and smaller developed economies are not sidelined, providing a more accurate reflection of the global economic footprint.
Factor-Based Selection
At the individual stock level, the ETF applies filters for valuation, size, and quality. Crucially, it imposes a one-percent maximum weight per security, with quarterly rebalancing. This prevents any single company from dominating the fund’s performance.
Performance Implications
The results of this strategy have been stark. While the ETF lagged behind the MSCI World by six percentage points in 2024—a year defined by the concentrated tech rally—it turned the tables in 2025. The Kommer ETF returned 10 percent, outpacing the benchmark by two percentage points. By 2026, the outperformance widened to nearly five percentage points. The lower reliance on US tech and the mitigation of currency risks from a weaker dollar have made this a compelling, if different, vehicle for growth.
Case Study 2: VanEck World Equal Weight Screened
For those seeking to remove the influence of market-cap dominance entirely, the VanEck World Equal Weight Screened UCITS ETF (ISIN: NL001040870) offers a radical alternative.
The Power of Equality
In this fund, all 250 constituent companies are weighted equally. By ignoring market capitalization, the ETF forces a massive reduction in the influence of US tech giants. The US allocation in this fund drops to approximately 39 percent, while the financial sector’s weight rises to 29 percent, and the healthcare sector to 13 percent.
Geographic and Sector Benefits
This structure provides a natural hedge against the "AI bubble." Furthermore, the ETF includes companies from South Korea—a country often excluded from the MSCI World because it is classified as an "emerging market." This geographic diversification helped the fund achieve a 14 percent return in 2025, beating the MSCI World by six percentage points.
Risk Considerations
However, the equal-weight strategy is not without its risks. Because it treats every company the same, it lacks the "winners-run-hot" benefit that propelled the MSCI World in 2023 and 2024. Investors must be prepared for periods of relative underperformance when a few tech companies are driving the broader market.
Case Study 3: Vanguard FTSE All-World High Dividend Yield
The Vanguard FTSE All-World High Dividend Yield UCITS ETF (ISIN: IE00BK5BR626) takes yet another path by filtering the investment universe through the lens of profitability and cash distribution.
Strategy and Methodology
The fund invests in over 2,000 companies globally that have a history of paying significant dividends. By focusing on firms that actually return cash to shareholders, the fund naturally filters out many high-growth, non-profitable, or speculative tech companies.
Implications of the Strategy
The result is a portfolio where the weight of the two main tech sectors is reduced to roughly 11 percent, and none of the "Magnificent Seven" occupy significant space. Conversely, the weight of financial, energy, and consumer staple stocks is effectively doubled compared to the MSCI World.
Market Results
This strategy has proven remarkably resilient over the last 18 months. With a 14 percent return in 2025, it outperformed the MSCI World by over two percentage points, building on a strong 2024 where it also outperformed by nearly five percentage points. It serves as a reminder that "boring" companies with stable cash flows can provide a safer harbor during times of tech-sector turbulence.
Summary of Implications for the Private Investor
The data from the past two years suggests a clear trend: the era of "set it and forget it" with a single, tech-heavy index may be reaching a point of diminishing returns for the prudent investor.
The Verdict on Concentration Risk
The concentration risk in the MSCI World is no longer a theoretical concern—it is a tangible driver of volatility. Investors who are heavily exposed to the AI theme are currently riding a wave that could crash if valuations in the semiconductor or software sectors are corrected.
Diversification as a Defensive Tool
The success of alternative ETFs like those from L&G, VanEck, and Vanguard demonstrates that diversifying by factor (quality, value), by weight (equal-weighting), or by objective (dividend yield) can lead to superior risk-adjusted returns. These strategies do not eliminate the AI factor—as many of these companies are still included in these funds—but they ensure that the portfolio’s fate is not tied solely to the volatility of a handful of stocks.
Strategic Advice
- Assess Portfolio Overlap: Investors currently holding an MSCI World ETF should calculate their exposure to the top ten holdings. If that concentration exceeds 20 percent, it may be time to consider a "satellite" allocation in a more diversified fund.
- Understand the Trade-off: Strategies that underperform during tech-bull runs (like the equal-weighted approach) require patience. Investors must be willing to accept that these funds will not match the index during years of extreme growth in a single sector.
- Currency and Geography: For European investors, funds that reduce US exposure naturally provide a hedge against the volatility of the US dollar.
As the AI boom matures and the market enters a potentially more fragmented phase, the focus for the individual investor must shift from chasing the highest-performing index to constructing a portfolio that is resilient to the inevitable shifts in market leadership. Whether through GDP-weighted indices, equal-weighting, or dividend strategies, the path to long-term wealth creation appears to be widening well beyond the narrow confines of the current tech giants.
