Tech guru Cathie Wood says Nvidia is the Cisco of the AI boom and warns its growth may falter

Cathie Wood has sounded the alarm on Nvidia, warning its spectacular growth is likely to slow, and comparing its stock surge to Cisco during the dot-com bubble.

The tech evangelist and Ark Invest CEO made the striking comments in a letter to her shareholders on Thursday.

She drew a parallel between Cisco riding high on demand for network hardware during the internet boom in the early 1990s, and Nvidia selling record amounts of graphics chips to companies developing artificial intelligence today.

It’s a “similar technology moment in time,” Wood said. She recalled that Cisco stock soared by 31 times in the 3.5 years to March 1994, then tanked 51% over the next four months as recession fears and the release of rival offerings caused customers to cut back on orders.

“Today, Nvidia is that company,” Wood said. She highlighted that the microchip stock has jumped 117-fold in the nine years since February 2015, and 23 times since October 2018, when the crypto winter hammered chip sales and sent Nvidia stock down 56% in three months.

Blistering growth

Wood’s point seemed to be that just as Cisco’s routers and switches enabled the internet revolution, Nvidia has emerged as the AI era’s defining company. And when a company plays such a key role in a new tech paradigm, it can see dramatic swings in its stock price.

Indeed, Nvidia has grown at a blistering pace in recent quarters as companies like Tesla and Oracle have scrambled to buy its chips. But the mad rush could mean its customers end up with…
