Caterpillar's stock is on fire right now.

The momentum suggests the market is rethinking how traditional sectors stack up in an AI-driven economy. For crypto investors watching macro trends, this pivot in how capital flows toward tech-enhanced legacy industries is worth paying attention to—it signals where institutional money sees long-term value creation, and those signals often ripple across asset classes including digital assets.
