Pacific Crest lowered its rating on Nvidia to underweight from sector weight, saying a survey of the chipmaker's customers indicate earnings will come in below expectations this coming year.
"We are downgrading NVDA … due to signs of desktop GPU [graphics processing unit] market saturation, lower margins from incremental Nintendo Switch revenue and a possible pause in the company's datacenter business this summer," analyst Michael McConnell wrote in a note to clients Tuesday. "Desktop graphics card manufacturers are noting material demand deceleration in sell-through since February."
Shares of Nvidia, which makes chips for the desktop graphics cards, are up 203 percent in the past 12 months through Monday on a successful launch of its new Pascal line of graphics chips. However, the stock is down 7 percent since the company's fourth-quarter earnings report Feb. 9.
