AI Stock Pickers Grapple With Dot-com Deja Vu

Investors seeking to capitalize on artificial intelligence are harkening back to another period when a technological advancement caused a market frenzy: the dot-com era.

Stocks are far from the mania that developed around internet-based businesses in the 1990s when the Nasdaq 100 soared more than 800% in five years. But surges in tech shares are posing similar challenges: how to pick winners and losers based on a nascent technology with vast potential that has yet to alter the economic landscape.

The similarities are undeniable for Michael O’Rourke, a chief market strategist at Jones Trading. While he says it’s still early in the investing cycle, O’Rourke is keeping a close eye on valuations, where fear of missing out can quickly send stocks into fantasy territory.

“If you pay a bad price even for a good asset it’s still a bad price and that’s where the risk is,” he said in an interview.

These days, conversations about frothy valuations start with Nvidia Corp., the chipmaker whose grip on the market for semiconductors powering generative AI programs like ChatGPT has made it the best-performing stock in the S&P 500 by far.
