When One Stock Becomes the Market

NVIDIA crossed $5 trillion — roughly 8% of the S&P 500. Index funds are becoming more concentrated in a few names, whether investors intend it or not.

NVIDIA has crossed a $5 trillion market cap — roughly 8% of the S&P 500 and 16% of U.S. GDP. One company now holds a market value larger than many national economies.

Over the last decade, millions moved from stock-picking to index investing via ETFs. It's simple and historically effective — but there's a growing hidden risk.

As giants like NVIDIA, Apple, and Microsoft grow faster than others, index funds become more concentrated in just a few names. When you buy "the market," you're actually buying more technology than you may intend.

• In the U.S., the top 5 companies account for over 30% of the S&P 500
• In India, the top 10 companies in the Nifty 50 make up nearly 60% of the index's weight

How to stay smart - Check index composition before you invest - Explore equal-weight or sector-balanced ETFs - Add exposure to international, alternative, and commodity assets - Don't let passive investing turn into blind investing

Indexes are a great starting point — but not the whole portfolio.
