SA analyst upgrades/downgrades: AMD, MU, META, DPZ

Seeking Alpha reports analysts upgraded Meta Platforms and Micron Technology while downgrading Advanced Micro Devices. Analysts pointed to Meta’s attractive valuation after a pullback and to Micron benefiting from an AI-driven memory supercycle, helping MU’s strong intraday move. AMD was singled out for a downgrade, creating headwinds for the chip supplier despite a notable price move shown in the related-stocks table. Market tables show sizable short-term moves (MU +13.15%, AMD +8.06%), indicating the analyst actions had immediate market impact on semiconductor and big-tech names. Overall, upgrades to META and MU support a bullish view for those names, while the AMD downgrade adds a bearish tone for that single-stock exposure, resulting in a mixed market signal for tech and chip sectors.
