On Monday, NVIDIA, ranked first in US stock trading, fell 2%, marking the second consecutive day of decline, with a transaction volume of $57.765 billion. The research team of JPMorgan Chase stated that compared to the average level of the past five years, the valuations of the seven tech giants are relatively low compared to other components of the S&P 500 index, and stocks such as Nvidia are far from reaching their peak. According to reports, Nvidia has been sued by three writers who claim that Nvidia used their copyrighted books without permission to train its artificial intelligence framework NeMo.
