Advanced Micro Devices, Inc. (ISIN US0079031078) stock rose 2.19 percent to about USD 504.20 on September 15, 2026 on Nasdaq as investors responded to strong second-quarter 2026 AI-driven growth and a new Overweight rating from Piper Sandler with a USD 600 price target, according to International Business Times and Ad-hoc News.
Q2 2026 results highlight AI-driven momentum
AMD reported second-quarter 2026 revenue of USD 11.54 billion, up 50 percent year over year, underscoring how rapidly the business is expanding, according to International Business Times.
In the same quarter, earnings came in at USD 1.66 per share, beating the consensus expectation of USD 1.62 per share, which signals a modest but clear upside versus analyst forecasts and shows that profitability is keeping pace with top-line growth, according to International Business Times.
A key driver was the data-center segment, where revenue doubled year over year to USD 6.7 billion in Q2 2026 and reached about 58 percent of total company sales, highlighting how central AI infrastructure and server demand have become to AMD's overall business model, according to International Business Times.
Piper Sandler sees further upside for AMD stock
Analyst David O'Connor at Piper Sandler initiated coverage of AMD with an Overweight rating and set a USD 600 price target on September 9, 2026, positioning the stock for further upside relative to its recent trading range, according to Ad-hoc News.
According to the same report, O'Connor's valuation is based on an expected annual EPS increase of 65 percent and revenue growth of 50 percent per year between fiscal years 2026 and 2030, applying a multiple of 24 times estimated fiscal-year 2028 earnings, which implies a premium valuation but reflects strong confidence in AMD's AI-oriented growth trajectory, as Ad-hoc News summarizes based on Yahoo Finance data.
That target sits meaningfully above the recent Nasdaq close around USD 504.20, leaving room of roughly 19 percent for potential appreciation if the analyst scenario plays out, while also underscoring how elevated expectations have become in the AI chip segment.
Valuation and risk context around the rally
On valuation metrics, AMD's market capitalization stood at about USD 823.1 billion at a share price of USD 503.99 on September 16, 2026, placing the company among the most valuable names in the S&P 500 and illustrating how aggressively the market is pricing its AI prospects, according to Ad-hoc News.
Separately, an analysis using the GF Value metric indicated that AMD was trading at USD 505.34 per share, about 79.4 percent above an intrinsic value estimate of USD 281.72, signaling significant overvaluation from that model's perspective and highlighting the risk that expectations embedded in the stock price may prove too optimistic if growth slows, according to GuruFocus.
Even against that cautious backdrop, AMD's share price has risen more than 213 percent over the past year as of around USD 504.62, reflecting strong investor demand for AI-exposed semiconductor names and suggesting that momentum investors continue to favor the stock despite valuation concerns, according to Invezz.
