Sean Peche, founder and portfolio manager at Ranmore Fund Management, has taken a bearish position on stocks tied to artificial intelligence, urging caution among investors as the largest technology companies pour billions into AI infrastructure.
"I’m a bear for AI-related stocks," Peche said. "The large technology companies are spending an absolute fortune on AI capex, and I think investors need to be very careful." His stance reflects a focus on measurable financial metrics rather than promotional narratives.
Peche emphasized that Ranmore prioritizes data when evaluating opportunities. "We look at the numbers, not the story. Most people listen to the story, but the problem with falling for stories is knowing when you’re wrong," he said. That empirical approach underpins his concern that investors often assume past high performers will continue to deliver similar returns, a pattern he warns is not guaranteed.
Describing the market enthusiasm for AI as a wave that could break, Peche said investors must recognize when to step aside. "You’ve got to exit these waves before they crash. And in AI, we’ve got a big wave going on," he said.
Peche’s remarks arrive after a difficult period for stocks associated with AI. The Nasdaq Composite experienced a sharp decline last week, logging its worst trading day since April 2025, with the selloff concentrated in AI infrastructure names. That rout followed Democratic gains in the midterm elections that, according to market reactions, raised concerns about potential delays to data center construction.
Spending on AI infrastructure remains significant. Microsoft has projected $175 billion in capital expenditures for the 2026 calendar year, a forecast that has drawn investor scrutiny over whether such large-scale spending will produce commensurate returns. At the same time, the cash impact of ramped-up investment has surfaced in corporate cash flows.
Quarterly free cash flow turned negative at Meta and Alphabet in the third quarter, and Meta, Alphabet and Amazon have paused share buybacks while broadening their funding activities through additional equity and debt issuance.
Not everyone shares Peche’s bearish view. Bernstein, in a recent note, said it does not find the bear case on AI "particularly compelling" and remains positive over a longer horizon, while acknowledging that the near-term outlook is difficult to predict.
The divergence in views highlights a market grappling with very large near-term capital commitments and mixed cash-flow dynamics among major technology companies. Investors and analysts are weighing whether elevated capex and shifting funding strategies will ultimately translate into sustainable returns or whether the current enthusiasm for AI-related investments is vulnerable to a pullback.
