SA analyst upgrades/downgrades: NVDA, GOOG, ORCL, SMCI

Seeking Alpha reports analyst rating changes across major tech names, with Nvidia receiving a positive revision and Alphabet upgraded on the view that its capital raise is well-timed amid favorable market conditions and emerging agentic AI use cases. Nvidia’s recent pullback is framed as a buying opportunity because commercial momentum remains strong, revenue estimates are still being revised higher, and visibility is robust. The piece also notes that Super Micro Computer was downgraded due to equity dilution risk, rising net debt, and reputational/legal concerns. Overall, the market tone is constructive for NVDA and GOOG, while caution is highlighted for SMCI.
