Nvidia shares jumped over 14 in pre-market trading on Thursday after reporting strong fourth-quarter earnings that beat analyst estimates. Nvidia reported revenue of $22.1 billion for the fourth quarter, up 265 year-over-year, with net income rising 769. The results were driven by continued strong demand for Nvidia's chips in artificial intelligence applications.
