Advanced Micro Devices (AMD) stock is back in focus after record Q1 2026 results, stronger Q2 revenue guidance, and new AI focused partnerships with Meta, Samsung, TCS, OpenAI, and other large customers.

Even after a strong run, the share price is still moving around short term, with a 1 day share price return of 3.07% in the red following a 7 day share price return of 15.22%. The 30 day share price return of 84.38% and 1 year total shareholder return above 300% point to powerful momentum that recent Q1 results, higher Q2 guidance and fresh AI partnerships have brought back into focus.

With AMD shares up more than 300% over the past year and trading just below many analysts' targets, the key question is simple: is there still mispricing here, or is the market already baking in years of AI growth?

Most Popular Narrative: 9.2% Undervalued

AMD’s most followed narrative pegs fair value at $450 per share, above the last close at $408.46, which puts current pricing in the spotlight.

Advanced Micro Devices (AMD) released its Q1 2026 financial results on May 5, 2026, delivering a "blowout" performance that has fundamentally shifted investor sentiment. Driven by a massive structural pivot toward AI infrastructure, the company exceeded analyst estimates across every primary metric. AMD is no longer just "the other chip company." It has successfully rewritten its thesis as a primary architect of the AI era. While the valuation is stretched, the fundamental growth in data centre revenue and the raised long-term TAM suggest that the premium may be justified if execution remains flawless.

Want to see what sits behind that $450 figure and 9.2% gap? The narrative leans heavily on acceleration in earnings, high AI infrastructure demand, and richer long term margins.

According to oscargarcia, the narrative treats AMD as a full scale AI infrastructure platform, not just a chip supplier, with data center, client, gaming, and embedded all feeding into that fair value. It also assumes that current earnings growth and margin trends can support that valuation at a discount rate of 9.54%, even with the share price already up sharply over the past year.

Result: Fair Value of $450 (UNDERVALUED)

However, this hinges on AMD keeping pace with Nvidia in high end AI GPUs, as well as managing export controls that could pressure margins and limit AI chip sales.

Another View: Earnings Multiple Sends a Louder Warning

That 9.2% “undervalued” fair value at $450 sits awkwardly next to where the market is actually pricing AMD today. The stock is on a P/E of about 135x, compared with a fair ratio of 75.8x, the US Semiconductor industry at 59.8x, and peers at 38.2x.

In plain terms, the current price asks you to accept a much richer earnings multiple than both the sector and peer group, and even the fair ratio that the market could move toward over time. If sentiment cools or forecasts reset, how much compression in that gap are you comfortable with?
