Artificial intelligence chipmaker Nvidia on Wednesday announced another quarter of astounding quarterly growth as investors try to decipher whether technology’s latest craze is overblown hyperbole or a springboard into a new era of prosperity and productivity. The results for November-January period blew past the analyst projections that shape investors’ perceptions, as has been the case since Nvidia’s high-end chips emerged as AI’s best building blocks three years ago. Nvidia’s fiscal fourth-quarter revenue surged 73% from the previous year to $68.1 billion while its profit nearly doubled. Nvidia’s stock price rose nearly 4% in extended trading after the numbers came out, but then backtracked and was slightly down a few hours later.
