Shares of artificial intelligence (AI) giant Nvidia (NASDAQ: NVDA) traded nearly 4.5% higher in the final half hour of trading on Friday. While there was no obvious catalyst behind the move, the stock market rebounded today after another difficult week and Nvidia also seems to be benefiting after a positive update from one of its suppliers. Taiwan-based Foxconn, also known as Hon Hai Precision Industry, reported fourth-quarter net income of $1.41 billion, which missed analyst estimates and also declined 13% year over year.
