On Wednesday night, Nvidia released its highly anticipated-slashed-dreaded quarterly earnings report — and Wall Street let out a sigh of relief, at least initially. Nvidia’s stock spiked by over four percent when trading resumed on Thursday morning. Other tech stocks received a boost, too, as did the S&P 500 overall. While headlines were still trickling out today about the stock market’s rally in the wake of Nvidia’s awesome third quarter, Nvidia’s stock did a swift 180, plunged again, and is now down by over 4 percent over the course of the day. And once again, other tech stocks followed.
