Think You’re Diversified with the S&P 500? Think Again.
It’s a 40% bet on 10 companies — and that’s a problem.
TL;DR: TODAY’S EDITION
The S&P 500 isn’t diversified anymore — the top 10 stocks make up ~40% of the index.
Those same 10 only generate 32% of earnings, while trading at far higher valuations (P/E 29.8 vs. 20.6 for the rest).
Buying the index today means betting heavily on Nvidia, Microsoft, Apple, Amazon, Meta, Broadcom, Alphabet, Tesla, and Berkshire Hathaway.
The Smart Money Portfolio, built from the best investors’ filings, holds 34 stocks and is already outperforming the S&P 500 by +4.8% YTD.
S&P 500
The Index Illusion
For decades, the S&P 500 has been sold as the safest way to “own the market.” A simple, diversified basket of America’s biggest companies. Buy it, hold it, and forget it.
But here’s the uncomfortable truth: in 2025, that diversification is mostly an illusion.
The Top-Heavy Problem

Credit: JP Morgan
The top 10 stocks in the S&P 500 now make up almost 40% of its market cap.
The other 490 stocks? They share the remaining 60%.
Yet those 10 giants only generate about 32% of the index’s earnings.
And it gets worse:
Top 10 average P/E ratio: 29.8
The other 490: 20.6
Translation: You’re paying a premium price for the biggest names, while under-owning the rest of the market.
Meet Your Real Portfolio
When you “buy the market” today, you’re actually loading up on just a handful of giants:
Nvidia, Microsoft, Apple, Amazon, Meta, Broadcom, Alphabet, Tesla, and Berkshire Hathaway.
Great companies, sure. But if they stumble, your “diversified” portfolio isn’t nearly as safe as you think.
A Smarter Way
Index investing used to be a good shortcut. Today, it means paying up for overvalued mega-caps and underweighting hundreds of solid businesses.,
That’s why we built the Smart Money Portfolio. Instead of blindly following market hype, it’s built from the real portfolios of the world’s best investors. Right now it holds 34 stocks, diversified across sectors — and since January it’s up +15.7% vs. +10.9% for the S&P 500.
Two of our positions posted double-digit gains in the last week alone: Broadcom (+15.9%) and Micron (+11.0%) — both riding trends beyond the Mag7 hype.
