Dot-Com Fears Rise with Tech Stocks Seeing $100 Billion Swings

Investors are excited about OpenAI’s expansion driving big gains in technology stocks, but a rising number of Wall Street pros fear that the wild pops that add tens of billions of dollars in value in mere minutes are signaling an unhealthy market reminiscent of the dot-com era.

Advanced Micro Devices Inc. took this rocket ride on Monday, as the company’s stock soared, briefly boosting its market capitalization by roughly $100 billion at an intraday high, after the chipmaker signed a deal with OpenAI that could lead to billions of dollars in revenue. This follows a 36% jump in Oracle Corp. shares last month, which added $255 billion to the software firm’s market value in a single session, after it gave blockbuster guidance for its cloud business, including an agreement with the ChatGPT operator worth $300 billion over five years.

“If any one of these deals falls through it has this domino effect downstream that I think is concerning,” said Brian Mulberry, client portfolio manager at Zacks Investment Management Inc., which has about $12 billion in assets. “It reminds me of what happened with telecom back in the mid-nineties.”

The moves come amid growing concern about a bubble forming around artificial intelligence as the key players — namely Nvidia Corp. and OpenAI — pledge billions of dollars in deals with a cohort of companies making infrastructure for the technology. As more money is spent, there’s mounting fear that the trend will end in a crash the way it did 25 years ago following the dot-com euphoria, when heavy investments were made in anticipation of internet traffic that took much longer to materialize.
