Nvidia’s stock NVDA, -8.99% tumbled 9% in afternoon trade, putting it on track to suffer the biggest one-day percentage loss in 5 1/2 years. It has now shed 15% since closing at a record high of $119.13 on Feb. 7. Volume of 28.1 million shares was nearly double the full-day average.
Troubling times ahead for NVIDIA - I assume the Ryzen launch has had an affect also. A strong AMD is bad news for NVIDIA. Think of all the profits from Ryzen that AMD will pour into it's GPU division etc!
I'm very happy that NVIDIA is moving down and AMD is moving up - hopefully they'll reach an equilibrium in the next few years, that will be awesome for us consumers, from a competition point of view
