Stocks dip on AI jitters, big banks kick off US earnings season - Reuters

Global equity markets opened the US earnings season on a cautious note, with major indexes slipping as renewed concerns over artificial intelligence valuations weighed on sentiment. The pullback comes as investors reassess the pace of AI-related spending and its near-term payoff, tempering the enthusiasm that drove much of last year's rally.

Against that backdrop, the largest US banks began reporting quarterly results, offering an early read on consumer health, credit conditions, and net interest income. Bank earnings are often viewed as a bellwether for the broader economy, since lending activity and loan-loss provisions can signal where growth and risk are heading.

What to watch: whether the AI-driven selloff proves to be a short-term repositioning or a deeper revaluation, and whether bank results confirm resilience or reveal strain. For now, the market appears to be balancing optimism about corporate profits against uncertainty over how quickly AI investments translate into earnings.
