Shares of Advanced Micro Devices (AMD) opened more than 5% lower Thursday—eventually slipping more than 9% in early morning trading—following the release of a key analyst note.

Today’s Warning

Analyst Toshiya Hari of Goldman Sachs initiated coverage on AMD with a “sell” rating and a 12-month price target of $11, which would represent a 22% slide from Wednesday’s closing price.

Although Hari credited the company for improving its execution of strategic initiatives under CEO Lisa Su, the analyst cited concerns that the stock has already priced in improvements in its competitive position. Hari also warned that AMD’s primary competitors, Intel (INTC - Free Report) and NVIDIA (NVDA - Free Report) , would likely fight back if the company did steal some market share.

“If AMD were to gain meaningful traction with its new products (e.g. Ryzen CPU, Naples CPU, Vega GPU) in 2017, we believe Intel and Nvidia would be likely to fight back in late-2017 and/or 2018 in the form of pricing concessions,” he said.

AMD has been a darling stock for the past year or so, gaining more than 400% over the last 52 weeks. Nevertheless, Hari expects AMD to underperform the market after its investor day in May.

Project Scorpio

The analyst’s warning comes on the same day that Microsoft (MSFT - Free Report) revealed the technology inside its next Xbox system, codenamed “Project Scorpio.” Integral to the new console will be Microsoft’s new Scorpio Engine, a “system-on-chip” that was designed alongside AMD.

There were some rumors that Project Scorpio would feature AMD’s new Ryzen CPU technology, but that doesn’t seem to be the case. Last month, shares of slid after an unfavorable review of the Ryzen 7’s PC gaming performance.

Bottom Line

AMD remains a Zacks Rank #2 (Buy). The company has seen positive earnings estimate revisions, and our current consensus estimates suggest that this will be a year of impressive EPS and sales growth. While short-term volatility is always a possibility, there is plenty of strength here.
