Shares of Nvidia (NASDAQ: NVDA) were trading down 2.4% as of 9:35 a.m. ET on Wednesday after one analyst issued a warning about the graphic chip maker's near-term growth. Susquehanna analyst Christopher Rolland cited declining selling prices for Nvidia's graphics processing units (GPUs) designed for playing video games on a PC, which presents near-term risk to one of Nvidia's largest sources of revenue. Nvidia has benefited from soaring demand for advanced computing applications, including data center operators buying high-powered graphics chips to process large data workloads with artificial intelligence.
