BofA Warns 'AI Put' Now Drives Stock Market More Than Bond Yields
BofA Global Research strategists argue the so-called 'AI put' has overtaken rising bond yields as the dominant risk factor for U.S. equities.
As bond markets remain volatile and global yields climb, many investors have focused on the threat that rising rates pose to U.S. stock valuations. But strategists at BofA Global Research say that framing misses the bigger picture, pointing instead to what they describe as the "AI put" as the more consequential force shaping equity markets.
The concept of a market "put" traditionally refers to a backstop — an implicit or explicit floor beneath asset prices provided by a central bank or policy intervention. In this context, BofA's strategists appear to be applying that framework to artificial intelligence, suggesting that investor confidence in AI-driven earnings growth has effectively become a self-reinforcing support mechanism for stock prices broadly.

BofA's warning reflects a wider debate on Wall Street about concentration risk and the degree to which a single thematic trade has come to underpin broader market sentiment. While surging bond yields can raise borrowing costs and compress valuations, a crack in the AI narrative could simultaneously remove both the earnings growth story and the sentiment premium investors have attached to the market.
