The U.S. tech sector is emerging as investors' top concern heading into what could be a volatile market period. Deutsche Bank's latest investor survey reveals a striking consensus: 57% of respondents identify a potential collapse in tech valuations as their primary market risk—particularly if enthusiasm around artificial intelligence momentum falters.

This worry isn't casual speculation. It reflects genuine anxiety about whether current valuations can be sustained once AI hype cycles normalize. The danger zone appears concentrated in companies trading at premium multiples, betting everything on continued AI-driven growth. If those narratives shift even slightly, the repricing could be swift and severe.

For traders monitoring cross-asset correlations, this is worth tracking. Tech sector rotation often precedes broader market adjustments. When AI enthusiasm begins to cool—and historically, every bubble eventually does—capital flows can migrate unpredictably across equities, bonds, and alternative assets including crypto.
