Investors are flocking to Deere and McDonald's as the latest 'HALO' companies—businesses believed to have AI immunity in an era of rapid technological disruption. These firms have become unexpected darlings on Wall Street, with their stocks gaining favor among investors seeking shelter from the AI revolution's potential impact on traditional industries.

Deere, the agricultural machinery giant, has long been considered resistant to automation due to the complex, hands-on nature of farming operations. Meanwhile, McDonald's continues to thrive as a consumer staple, with its business model relying heavily on human service and local franchise operations that are difficult to fully digitize. Both companies represent a shift in investor strategy, moving away from tech-heavy portfolios toward businesses with tangible, human-centric operations.

The 'HALO' investment thesis reflects growing concerns about AI's potential to disrupt white-collar jobs and traditional business models. As AI capabilities expand, investors are increasingly seeking companies with durable competitive advantages that technology cannot easily replicate. Deere and McDonald's exemplify this trend, with their established market positions and operational models that require significant human involvement.
