How the ‘AI put’ has become the only thing that matters for stocks

Bank of America Global Research strategists argue that the primary risk to U.S. equities is not rising global bond yields, but the sustainability of the AI-driven earnings narrative. The "AI put" refers to the market's implicit assumption that artificial intelligence investment will keep corporate profits growing fast enough to justify current valuations, effectively cushioning stocks against other macro shocks.

That framing matters because it shifts how investors might interpret bad news. A yield spike is typically treated as a mechanical headwind for equity valuations, since higher discount rates compress the present value of future earnings. If strategists are right, however, the more consequential question is whether AI-related capital spending and revenue translate into durable profit growth, or whether expectations have run ahead of results.

What to watch: forward earnings guidance from major technology and semiconductor companies, AI capital expenditure trends, and whether bond yields rise because of stronger growth or rising inflation risk. Each scenario carries different implications for equity leadership, making the source of yield moves as important as the moves themselves.
