Seeking Alpha reports rating changes for MU, AMD, AMZN and RIVN

what happened

Seeking Alpha reported several analyst rating changes involving four companies. Rivian Automotive was upgraded to Positive after third-quarter deliveries rose 45.8% year over year, supported by strong adoption of the lower-cost R2 SUV. The analyst said the delivery momentum could lead to higher estimates, revenue gains and an improving profitability profile.

Micron Technology was upgraded to Neutral. The analyst believes the shares may be approaching the final phase of a major shakeout, while AI inference tailwinds and shareholder-related catalysts could provide support after CHIPS Act restrictions expire on December 9, 2026. The analyst also expects Micron to make major investments before the end of this year.

Amazon.com was downgraded to Hold. Although the stock has gained 13% since June, the analyst cited mounting margin pressure from inflation, higher fuel costs and increased interest expenses, along with the risk of slower e-commerce growth. Advanced Micro Devices was also cut to Hold by Louis Gerard, who noted a gain of more than 41% since early September and stretched valuation metrics, despite management’s projection that data-center revenue will double to $70 billion by 2027.

why it matters

The rating changes highlight different market concerns around operating momentum and valuation. Rivian and Micron were assessed through the lens of deliveries, investment and AI demand, while Amazon and AMD faced greater scrutiny over costs, margins and share-price valuation.
