The 'Magnificent Seven' is no more. Time to pick winners and losers as group's correlation breaks down

The "Magnificent Seven" doesn't trade as a monolith anymore, challenging investors to be more discerning when picking through the market's biggest stocks rather than viewing them as a single trade. CNBC calculated the rolling 60-day correlation of daily returns for each of the 21 unique pairs among the Magnificent Seven — which comprises Alphabet , Amazon , Apple , Meta Platforms , Microsoft , Nvidia and Tesla . The average of those correlations recently fell to its lowest level in more than a decade, suggesting the group is trading less like a cohesive block than it has historically. This marks a departure for a group that's often discussed together because of its size and influence over the broader market.
