Rocket Lab USA, Inc. (RKLB) shares plummeted 5.05% during intraday trading on Monday, extending recent losses for the aerospace company.

The decline comes as Rocket Lab continues to face pressure following its recent inclusion in the Nasdaq 100 index. Historical data shows that new entrants to the Nasdaq 100 often experience short-term declines, with Rocket Lab having fallen more than 15% in the week after joining the index on June 22 amid a broader tech sector selloff.

Other recent additions to the Nasdaq 100 have shown similar patterns, with CoreWeave and Nebius also experiencing significant declines post-inclusion, highlighting the challenges new index constituents often face in their initial trading periods.
