A top strategist has a warning for retail investors chasing the AI rally

Maxx Kettner, HSBC's chief multiasset strategist, is cautioning retail investors about the pace of change in artificial intelligence investing, noting that the goal posts are constantly moving. His warning comes as AI-linked names have driven much of the market's recent gains, drawing heavy attention from individual investors.

The core of Kettner's point is about expectations rather than any single stock or sector. In a fast-evolving theme like AI, the benchmarks investors use to judge companies—technological leadership, revenue timelines, competitive position—can shift quickly. What looked like a durable advantage months ago may be reassessed as new entrants, products, or spending trends emerge. That makes it harder for anyone, particularly those without deep research resources, to rely on a fixed view of who the winners will be.

For markets, the remark is a reminder that thematic enthusiasm can outrun fundamentals, and that concentration in popular trades can amplify volatility when narratives change. What to watch: how AI-related earnings and capital spending guidance evolve, whether leadership broadens beyond the largest names, and how strategists revise their frameworks as the technology matures. None of this predicts direction—it simply frames the uncertainty investors are navigating.
