And where are the opportunities beyond the Mag Seven? Morningstar Holland’s Chief European Market Strategist Michael Field is one of the researchers who investigated this.

Key Quote on Opportunities Beyond Magnificent Seven Stocks in 2026
It’s great to have the reward, but what are we risking to get that? And if indeed we’ve got more than a third of our market caps generated all on one sector, then that’s a huge bet, particularly now on AI, as that ramps up. So great, if it works, we’re all going to make a lot of money, but if it doesn’t work, then we’ve got the potential to lose a lot of money.

The Takeaway: Be aware of how much exposure you have in your portfolio to Magnificent Seven stocks. Field says it’s fine being exposed to Nvidia and other members of Big Tech.
