Nvidia's stock has been experiencing a significant surge, closing the market value gap with Apple. Two and a half years ago, Nvidia was $2 trillion behind Apple in stock market value, but recent weeks have seen this gap narrow dramatically to $400 billion, fueled by optimism around the future of artificial intelligence (AI). A year ago, Nvidia was $2.7 trillion behind Apple, but now it's only $400 billion short of overtaking Apple as the most valuable company. This surge in Nvidia's stock is attributed to its role in powering AI supercomputers, with its shares hitting record highs, last up 2.5% and reaching $900 in premarket trade. Analysts are watching closely as Nvidia continues to gain value, with some predicting it could surpass Apple if the latter doesn't impress investors with AI advancements soon. Broadcom's upcoming earnings report is also highly anticipated, given its potential impact on Nvidia's stock value.
