U.S. stocks opened higher today. The Dow Jones Industrial Average increased by 0.33%, the S&P 500 rose by 0.48%, and the Nasdaq Composite led the gains with a 0.58% increase.

In individual stocks, NVIDIA, the AI chip giant, performed notably, opening with a 1.5% gain. The company recently announced the launch of the Nemotron 3 series open-source large model, further consolidating its technological position in the AI field. The launch of this product line reflects the tech leaders' continued investment in generative AI competition.

However, there was also clear market divergence. The stock of robotic vacuum manufacturer iRobot experienced a tragic fall—opening with a 69% plunge. The company had previously announced bankruptcy protection, and this sharp drop in stock price also reflects market pessimism about its prospects. This also reminds investors that even once-flourishing consumer electronics companies need to be cautious of risks amid changing market conditions.
