Nvidia ($NVDA) experienced significant fluctuations in its stock value, with a pre-market rise of ~4% and a potential value accretion of over $1 trillion this year. The company's stock split rumors and nearing $1,000 mark generated market interest, but it faced a sharp decline, erasing gains and falling 5% in a single day, marking its largest percentage decrease since October 2023. Despite recent volatility, Nvidia remains a key player in the AI chip business and is on track to overtake Apple as the second-most-valuable company.
