Analysts Upgrade Microsoft, Palantir and Marvell on AI Growth

Wall Street analysts upgraded three technology stocks to buy ratings during the second week of October 2026, citing catalysts in artificial intelligence. Melius Research upgraded Microsoft on October 5, pointing to the growth of Azure cloud services and the adoption of AI agents.

Goldman Sachs upgraded Palantir Technologies on October 8, noting increased demand for the company's Artificial Intelligence Platform as businesses seek to maintain control over proprietary data. TD Cowen upgraded Marvell Technology on October 7 following the company's Investor Day on October 6.

Marvell CEO Matt Murphy raised the company's fiscal 2028 revenue outlook to approximately $20 billion, driven by demand for custom silicon for AI workloads and connectivity equipment. While all three firms show AI-driven potential, analysts identified Marvell as having the most attractive valuation relative to its expected growth.
