Shares of semiconductor manufacturer Nvidia (NASDAQ:NVDA) -- a supplier of chips for everything from playing video games to mining cryptocurrency to performing artificial intelligence tasks -- are posting a tidy 2.3% gain as of 2:25 p.m. EDT Wednesday. And you can thank the friendly analysts at Rosenblatt Securities for that. Image source: Getty Images. So what In a note out this morning, Rosenblatt raised its price target on Nvidia stock 25% to $250 -- that's incidentally about 25% above where the stock trades today. Rosenblatt cites Nvidia's earnings power on "best-in-class AI" and its opportunities in next generation networking and data processing as well as autonomous driving software, and apparently believes even the company's 94-times-earnings valuation currently is not too much to pay for Nvidia stock.
