Technology investors had gotten used to a good thing — positive momentum that seemed unstoppable. Giants in the industry led the Nasdaq to two years of double-digit gains — and the individual stocks themselves offered shareholders mind-boggling returns. For example, Nvidia (NASDAQ: NVDA), the world’s leading artificial intelligence (AI) chip designer, saw its stock surge 1,600% over the past five years, and Palantir Technologies, an AI-driven software player, advanced more than 800% since its 2020 market debut.
