Investors urged to look beyond US as diversification gains traction

Goldman Sachs' global strategy team is advising investors to diversify beyond long-dominant US stocks and the dollar, asserting that the 'era of diversification has begun.' This strategic shift is predicated on high US market concentration and valuations, particularly in tech, which are no longer justified by relative earnings growth, alongside rising US deficits and a weakening dollar. Concurrently, stronger growth signals from China and looser fiscal policies in Germany are attracting capital to cheaper ex-US markets, presenting broader opportunities in areas like European mid/small-caps and diverse investment strategies.

Analysis

Goldman Sachs' global strategy team posits that the prolonged period of United States market and dollar dominance is reaching an inflection point, heralding an 'era of diversification.' The core of their argument rests on the observation that over a decade of US outperformance has resulted in significant concentration risk for investors, tied to a single geography, currency, and a narrow group of stocks. This concentration is becoming less justifiable as US equity valuations, particularly in the technology sector, have outpaced relative fundamentals; the report notes that the rise in US price-to-book ratios began to exceed underlying earnings and return on equity growth around 2022. Concurrently, macro-level shifts are undermining the US-centric thesis, including rising US deficits and policy uncertainty that are weakening the dollar. In contrast, emerging fundamental strengths elsewhere, such as stronger growth signals from China and looser fiscal policy in Germany, are enhancing the appeal of more attractively valued international markets. The analysis specifically highlights opportunities in European mid- and small-cap equities and a broader mix of investment styles, as the US now commands a valuation premium over European and Asian peers that is above its long-term average.

Key Decisions for Investors

• Investors with heavy allocations to US large-cap equities should reassess their portfolio concentration in light of the valuation and risk factors identified, as the justification for the US valuation premium appears to be weakening.
• Consider initiating or increasing exposure to non-US markets, specifically focusing on European mid- and small-cap stocks and other regions where valuations are more attractive and supported by improving local fundamentals.
• Monitor the trajectory of the US dollar, relative earnings growth between the US and international markets, and shifts in fiscal policy in key economies like the US and Germany, as these are the primary catalysts for the recommended diversification strategy.
