Nvidia is a company that makes computer parts, like special chips that help computers think and learn. Their shares, or pieces of the company that people can buy, are not doing very well today. One reason is because another company, Super Micro Computer, did not make as much money as people thought they would.
Nvidia is also working with another company, Samsung, to make better chips for their computer parts. This is good news for Nvidia, and people think it will help them make more money in the future. But for now, the shares are not doing well.
