👉 See what’s happening beneath the surface →

The market is entering a new phase.

For the last two years, investors have rewarded companies willing to spend aggressively on AI.

Now they're starting to ask a tougher question:

Who will actually turn those investments into profits?

This earnings season will begin answering that question.

Companies like IBM and Apple are showing that AI isn't just about building bigger models—it's about creating products that customers will actually use.

At the same time, Buffett's warning serves as an important reminder.

Markets often become the most optimistic just before expectations become the hardest to meet.

The opportunity remains enormous.

But as valuations climb, selectivity matters more than ever.

The next winners may not simply be the companies spending the most on AI—they'll be the ones that prove those investments can generate durable earnings growth.
