Advanced Micro Devices Inc.’s stock fell Wednesday, bucking the sharp gains enjoyed by its peers and the broader stock market, amid growing concerns that cryptocurrency miners may start going elsewhere for their graphics cards. The chip-maker’s stock AMD, -1.27 closed down 1.3% at $13.23, paring earlier losses of as much as 2.3% at an intraday low of $13.09. With volume of 84.8 million shares, the stock was the most actively traded on the Nasdaq exchange. Meanwhile, the PHLX Semiconductor Index SOX, +1.77 climbed 1.8% and the S&P 500 index SPX, +0.88 rallied 0.9%. Analyst Christopher Rolland at Susquehanna Financial said that after a recent trip to Asia, he can confirm recent media reports that key rival Nvidia Corp.NVDA, +3.53 will release two new cryptocurrency-specific graphics processing units (GPUs) during the third quarter. Nvidia’s stock surged 3.5% to snap a four-session losing streak. “As these new products are more price competitive, they may pose a risk to AMD’s current offerings in the market,” Rolland wrote in a note to clients. “[The] new cards may upset AMD’s alt-crypto coin dominance.” Nvidia said it had no comment. AMD did not respond to a request for comment. via
