Global markets are entering a new ‘postmodern' era. This is how investors can win big, says Goldman Sachs

Goldman Sachs' Peter Oppenheimer asserts that global markets are entering a new 'postmodern cycle,' characterized by reversing globalization, elevated bond yields, and persistent inflation, which will significantly temper returns for broadly diversified portfolios and index funds. This paradigm shift, moving away from the favorable conditions of the past four decades, necessitates a strategic pivot towards skillful stock picking across diverse sectors, styles, and geographies to identify winners and losers, with opportunities potentially expanding beyond U.S. mega-cap tech into areas like Europe.

Analysis

Goldman Sachs global equity strategist Peter Oppenheimer posits that markets are transitioning into a 'postmodern cycle,' departing from the four-decade paradigm of falling interest rates, disinflation, and increasing globalization that broadly lifted equity indexes. This new era is defined by reversing globalization, elevated government debt sustaining higher bond yields, and more persistent inflation, which collectively are expected to lead to disappointing returns for broad market indices like the S&P 500. The rationale is that stretched valuations and historically high corporate profit margins leave minimal scope for further multiple expansion to drive returns. Consequently, the environment is shifting to favor skillful stock picking over passive index-tracking strategies. The AI revolution is identified as a primary catalyst that will widen the performance gap between corporate winners and losers across various sectors and geographies. While acknowledging the past dominance of U.S. technology leaders like Nvidia and Microsoft, the report cautions against the high concentration in these names and advises investors to diversify. Specifically, it highlights potentially 'enticing opportunities' in Europe, where companies are increasing capital expenditures to enhance productivity and innovation.

Key Decisions for Investors

• Investors should re-evaluate heavy allocations to passive index funds like those tracking the S&P 500, as their future returns are projected to be significantly lower than in previous supercycles.
• Consider shifting capital from passive to active strategies to exploit the expected increase in performance dispersion among individual stocks, styles, and geographies.
• It is prudent to reduce concentration risk in U.S. mega-cap technology stocks and actively seek diversification by exploring non-U.S. markets, with a specific focus on European equities poised to benefit from productivity-enhancing investments.
• Focus security selection on identifying companies across all sectors, not just technology, that can effectively leverage AI to generate tangible productivity gains, as this will be a key determinant of outperformance.
