Rocket Lab (RKLB +10.38%) stock is getting hit with strong selling action in Tuesday's trading. The company's share price had fallen 7.9% as of p.m. ET. Meanwhile, the S&P 500 was off 0.3% at the same point in the daily session, and the Nasdaq Composite was off 0.6%. The stock had been down as much as 11% earlier in the session.
Rocket Lab is seeing big sell-offs today in conjunction with bearish momentum for the broader market connected to valuation concerns for top artificial intelligence (AI) stocks and also the market at large. Geopolitical risk factors are also weighing on valuations across sectors today, and companies with growth-dependent valuation profiles are being hit particularly hard.

Rocket Lab sinks amid uptick in bearish AI sentiment
While Rocket Lab is much more of a space stock than an AI stock, that doesn't mean that it's immune to the impacts of reappraisals for valuations in the AI category. Bullish momentum for AI stocks has played a big role in supporting positive sentiment for the broader market over the last year, and it's not shocking to see the company's share price sink in a day when investors are feeling skittish about AI valuations.

Key Data Points
There are a couple of key AI-specific catalysts that are driving sell-offs for stocks today. For starters, news hit the wire that Chinese artificial intelligence company DeepSeek is developing its own AI chips to compete with Nvidia's offerings. Investors also had a negative reaction to Samsung's recent quarterly report. While Samsung posted impressive results, it also laid out ambitious spending targets -- and there's some doubt among investors as to whether the long-term demand outlook justifies its ambitious spending plans.
Geopolitical uncertainty is also weighing on Rocket Lab
Iran resumed strikes on oil tankers passing through the Strait of Hormuz today, upending hopes that its conflict with the U.S. could be drawing to an imminent close. Iranian officials said they would not resume peace talks if U.S. leaders continued to make threats.
Additionally, President Donald Trump's comments at a summit that began in Turkey today appear to have once again called his support for NATO into question. While it's possible that today's surge in bearish momentum related to geopolitical risk factors could reverse in the not-too-distant future, investors should also move forward with the understanding that geopolitical dynamics could continue to be a major source of volatility.
