Carlisle Warns All AI-Impacted Stocks Face Extended Underearning Period

What was said

"I think the risk is just that for a period of time, and I don't know how long this is, but could be 5 years, they just under-earn on what they've invested and the multiples come down as a result."

Tobias Carlisle argued that major tech companies including Meta and Booking face a prolonged period of underperformance as they overspend on AI infrastructure that may not generate expected returns. He warned that AI chips age faster than traditional infrastructure, creating greater risk than past technology build-outs like fiber optics.
