Advanced Micro Devices (AMD) stock crossed $300 for the first time, closing at $303 after a 6% increase, with an additional 4% rise in after-hours trading. This surge is attributed to a positive shift in investor sentiment, driven by strong demand for AI chips and favorable analyst upgrades. Investment firm Stifel raised AMD's price target to $320 from $280, while Bank of America set a target of $310. The semiconductor sector is thriving, particularly due to AI, with AMD's growth closely linked to Taiwan Semiconductor Manufacturing Company (TSMC), which reported strong results that further boosted confidence. AMD's CEO Lisa Su's recent visit to South Korea also played a role in enhancing investor confidence. Despite a strong Q4 2025 earnings report, which showed earnings per share of $1.53 and revenue of $10.3 billion, the stock initially fell due to high expectations. Analysts now anticipate that AMD's stock may trade between $296 and $315 in the short term, with the upcoming May 5 earnings report being pivotal for the stock's future trajectory.
