In 1990, the top 10 stocks made up about 18% of the S&P 500.
By 2015, still around 19%.
Today? Over 40%.
That's not a bull market. That's a handful of AI mega-caps carrying an index that 500 companies are supposed to share.
Here's why that matters. When 10 names drive nearly half the index, a single earnings miss, one bad quarter, can move your entire "diversified" portfolio.
Most investors don't know this. They own the index, they feel protected, and they move on.
But diversification used to mean something different. It meant spreading risk across sectors, geographies, and asset classes that don't move together. Not owning 500 companies where 10 of them call the shots.
This is exactly why high-net-worth investors are looking beyond public markets. Private credit. Real assets. Strategies that don't live and die by the Nasdaq's mood on a Tuesday.
The S&P can keep climbing. But climbing with 40% of your weight on 10 stocks isn't the same ride it used to be.
What does your diversification actually look like right now?
