Rocket Lab USA, Inc. (RKLB) saw its stock price plummet 11.84% during Monday's intraday trading session, following a massive surge in the previous month. The steep decline is likely attributed to investors taking profits after the aerospace company's shares skyrocketed 155% in November.

According to a report from Barron's, RKLB's plunge on Monday was part of a broader selloff in the aerospace and defense sector, with several other companies like Joby Aviation, Archer Aviation, and Intuitive Machines also experiencing double-digit declines. The report suggests that these sharp drops may be a result of profit-taking by investors, as many of these stocks had seen significant gains in recent weeks or months.

RKLB's stock price had surged in November, following a strong third-quarter earnings report that showed continued growth in the company's space systems and launch services businesses. However, after such a substantial run-up, it appears that investors decided to cash in on some of those gains, leading to Monday's steep sell-off.
