Nvidia's market capitalization has surged back above $3 trillion, making it the third-largest company in the world. This resurgence is driven by a 37% increase in its stock price over the past seven weeks, bolstered by strong investor interest in generative AI and significant investments in AI data centers. Nvidia's market cap swing since yesterday's low has reached $235 billion. The company now ranks behind Apple and Microsoft, with market caps of $3.4 trillion and $3.2 trillion, respectively. The broader semiconductor sector has also seen gains, with major chip stocks like Intel, Advanced Micro Devices, and ON Semiconductor rising in premarket trading. Nvidia shares rose 2.4% premarket following Micron's 15% surge.
