Most Americans who invest do it without ever picking a single stock.
They put money into an index fund, usually one that tracks the S&P 500, and let the market do the work
For years, that felt close to a free lunch. Buy the whole market, keep costs near zero, and ride the long climb of American business. The catch is that the S&P 500 stopped being the whole market in any real sense.
A small cluster of technology giants now sits at the top, and their combined weight has grown so large that owning the index means making an outsized bet on a handful of names. Seven stocks, the group often called the Magnificent 7, made up about 32.5% of the S&P 500 as of July 2026, according to The Motley Fool, which drew on figures from Stock Analysis. So when the second largest money manager on the planet decides to sell investors more ways to own American stocks right now, it is worth asking why.
