SA analyst upgrades: NVDA, BABA, C, BA, SWKS, DVAX

Here are the latest stock rating upgrades by Seeking Alpha analysts:

Nvidia (NASDAQ:NVDA). Sell to hold by Sungarden Investments.

Alibaba (NYSE:BABA). Hold to buy by Oliver Rodzianko. “Alibaba Group Holding Limited delivered solid 7% revenue and 36% EBITA growth despite geopolitics; its cloud segment’s surging AI demand signals massive long-term potential—but watch U.S.-China relations closely.”

Citigroup (NYSE:C). Sell to buy by Bay Area Ideas. “While caution is warranted due to recent consolidation, I believe Citi’s technical and fundamental strength justifies a bullish outlook and multiple expansion.”

Boeing (NYSE:BA). Sell to hold by Envision Research. “The backlog changes reported in its Q1 earnings report suggest profit stability ahead for BA. With the latest new orders from Qatar Airways, its current capacity is fully booked for the next 8~10 years. Its Global Services division is another positive, given the recurring nature of its revenue and the vast existing customer base.”

Skyworks (NASDAQ:SWKS). Hold to buy by The Techie.

Dynvax (NASDAQ:DVAX). Hold to buy by Out of Ignorance.
