From Assets to Alpha: David Kostin on US Equities
Goldman Sachs Chief U.S. Equity Strategist David Koston forecasts a 20%+ return for U.S. stocks in 2026 based on economic stability and earnings growth, while distinguishing between the fundamentally grounded public AI market and a potentially bubble-ridden private sector driven by reflexive capital inflows. Despite projecting long-term annualized returns of 6.5% over the next decade, Koston identifies immediate opportunities in undervalued healthcare, stable middle-income consumer sectors, and AI-driven revenue generators as institutional funds struggle to outperform benchmarks. As Koston transitions from the Chief U.S. Equity Strategist role to an Advisory Director position in 2026, his successor Ben Snyder will inherit a market characterized by high concentration risk and shifting investor behavior from asset accumulation to alpha generation.

Should investors worry about market concentration?
David Kostin, Owen Lamont, Alison Nathan
Strategists David Kostin and Owen Lamont converge on the projection that U.S. equity markets face a decade of sub-10% returns driven by extreme concentration and elevated valuations, though they diverge on whether the top ten stocks' dominance itself constitutes the primary risk. Kostin warns that the current 36% market cap concentration creates a negative equity risk premium and recommends shifting to equal-weighted indices, while Lamont argues that future volatility will stem from AI-driven creative destruction and mean reversion rather than portfolio structure. Both analysts acknowledge that the sustainability of the "magnificent seven's" growth and potential AI bubbles remain critical variables that could accelerate a decline in market performance over the next ten years.
