Astera Labs, CoreWeave, Nebius, Rocket Lab, Teradyne rise on Nasdaq-100 index inclusion announcement
Tech stocks Astera Labs, CoreWeave, Nebius, Rocket Lab, and Teradyne have risen as much as 8.9% in premarket trading on Friday, thanks in part to Nasdaq’s announcement that the five companies will join its flagship Nasdaq-100 index starting June 22.
As part of the index operator’s quarterly rebalance, which affects some $1.4 trillion in assets within the Nasdaq 100 ecosystem, the companies will replace Charter, Zscaler, Cognizant, Insmed, and Verisk — relatively slow-growth legacy businesses that have lingered around the bottom of the index in market cap terms of late. Most of those stocks slipped slightly on the news.
With CoreWeave and Nebius as two of the major players in the neocloud space, and Astera Labs and Teradyne specializing in making AI hardware and semiconductors, the latest additions reflect how the index is upping its exposure to the AI infrastructure stack. Back in December, Nasdaq also added AI data storage names Seagate Technology Holdings and Western Digital, as well as AI server manager Monolithic Power Systems as part of its quarterly rebalance.
