Reflecting on Three Decades: David Kostin on Market Outlook, AI, and the Evolution of Equity Strategy

As David Kostin prepares to transition from his role as Chief U.S. Equity Strategist at Goldman Sachs after a distinguished 31-year tenure, he offers a comprehensive retrospective on the current state of equity markets, the reality of the AI landscape, and the structural shifts he has witnessed in global finance.

Market Sentiment and the "AI Bubble" Debate

Addressing the pervasive anxiety regarding a potential "AI bubble," Kostin provides a nuanced framework, distinguishing between price and capital availability in both public and private markets. He argues that in the public space, companies like NVIDIA have seen their share prices increase by 12-fold alongside a commensurate 12-fold increase in earnings, suggesting that valuations are grounded in fundamental growth rather than speculative excess.

Kostin contrasts this with the private market, drawing on George Soros’s theory of reflexivity—the idea that price changes themselves influence the valuation of an enterprise. He warns that while public markets are experiencing healthy capital availability, the private AI sector risks a "recursive process" where growth is driven by circular vendor financing, which may prove unsustainable.

Navigating Current Market Volatility

Reflecting on the 2025 landscape, Kostin characterizes market volatility as being "right in line with the last five years," with the VIX hovering around 19. While investors have felt challenged—notably due to the difficulty mutual funds have had in outperforming style benchmarks—Kostin identifies three key areas of opportunity for the future:

  1. Healthcare: Statistically the cheapest it has been in 30 years on a relative basis.
  2. Consumer Retail: Stabilizing middle-income components of the economy poised to benefit from future tax reforms.
  3. AI Revenue Beneficiaries: A shift in focus from companies merely using AI for margin improvement to those utilizing it to drive concrete revenue growth.

The Long-Term Outlook for S&P 500

Kostin maintains a cautious, albeit positive, long-term view for the S&P 500. With the index trading at approximately 23 times forward earnings, he anticipates annualized total returns over the next decade to fall within a 3% to 10% range, likely landing toward the lower end. He cites high market concentration as a primary risk factor, noting that a narrow portfolio typically warrants higher prospective volatility, which is currently not being adequately priced in by investors.

Evolution of the Strategist’s Role

Looking back at his career, which began during the turbulent market of 1994, Kostin highlights how the discipline of equity strategy has evolved. He describes a shift from an "asset-focused" approach to an "alpha-focused" one, where investors increasingly trade based on specific company attributes—such as balance sheet strength or exposure to non-U.S. revenues—rather than viewing companies merely as generic assets.

Despite these changes, he emphasizes that the fundamental framework—the "four legs of the table" consisting of the economy, earnings, valuation, and money flow—remains the bedrock of successful investment strategy. His advice to those entering the workforce remains anchored in this perspective: to succeed, one must deeply understand how their specific role contributes to the broader commercial process and to remain curious about the varying risk tolerances and horizons of a diverse global client base.

As he moves into an advisory director role in 2026, Kostin leaves behind a legacy defined by his ability to bridge complex economic theory with actionable market insights, setting a standard for his successor, Ben Snyder, to continue in the decades to come.
