Apple's New CEO Faces Challenges as Giant Hits $4.6 Trillion

John Ternus has taken over as CEO of Apple, inheriting a $4.6 trillion giant facing questions about its next growth engine and innovation.

Cook transformed Apple from a sub-$350 billion company into a global powerhouse during nearly 15 years as CEO.

The shares soared 2,258% under Cook's tenure, with the stock benefiting from its image as an anti-AI play during periods of angst over the technology.

Ternus will face an early test at a critical event next week, where he is expected to unveil a foldable version of the iPhone, along with other product updates.
