What the S&P 493 represents

The S&P 493 is gaining attention as investors look beyond the Magnificent Seven and reassess where growth and diversification may come from in today’s equity markets. With market concentration at historic highs, a handful of mega cap companies have driven much of the S&P 500’s returns, raising questions about what lies beneath the surface.

In this episode of The Bid, host Oscar Pulido speaks with Ibrahim Kanan, Head of the U.S. Core Equity Team within BlackRock’s Fundamental Equities Group, about the growing relevance of the S&P 493 — the broader set of companies outside the largest names. They explore how market concentration has evolved, why a $200 billion company represents only a small fraction of the index, and what that means for portfolio exposure.

The conversation highlights how earnings growth is beginning to broaden beyond mega cap stocks, supported in part by the expanding impact of AI investment across sectors. From industrials and healthcare to consumer and financials, companies are both benefiting from AI infrastructure spending and adopting AI to improve operations. As dispersion across companies increases, the discussion also examines how active investing, differentiation, and stock selection may play a larger role in navigating today’s equity market.
