Midday movers: Boeing, HP, Micron and more

Investing.com -- U.S. stocks were wobbling on Monday, with last week’s positive sentiment diluted by Moody’s rating agency downgrading its outlook for the U.S. long-term credit rating.

Here are some of the biggest U.S. stock movers today:

• Boeing (NYSE:BA) stock rose 4.3% after Bloomberg News reported that China is mulling potentially resuming purchases of the planemaker's fast-selling 737 Max jets.

• HP (NYSE:HPQ) stock rose 0.6% after Citigroup upgraded the computer hardware manufacturer to ‘buy’ from ‘neutral’, citing a favorable valuation, substantial cost reductions and the possibility for AI integration on PCs.

• Micron (NASDAQ:MU) stock fell 1.3% after Chinese chipmaker Yangtze Memory Technologies filed a lawsuit against the U.S. rival alleging infringement of eight of its patents.

• Robinhood (NASDAQ:HOOD) stock rose 1.7% after Google-parent Alphabet (NASDAQ:GOOGL) said it had dissolved its stake in the trading app operator, a few months after the tech giant slashed its stake in the company by nearly 90%.

• Novo Nordisk (NYSE:NVO) stock rose 0.3% after the drugmaker presented data over the weekend showing that the heart protective benefits of its popular obesity drug Wegovy are not solely due to weight loss.

• Plug Power (NASDAQ:PLUG) stock rose 2.2%, continuing Friday’s hefty losses after the hydrogen fuel-cell firm pulled its 2023 guidance, citing “unprecedented supply challenges.”

• Tyson Foods (NYSE:TSN) stock fell 2.8% after the food processor announced the closing of two of its case-ready meat production facilities in the US.

• Capital Product (NASDAQ:CPLP) stock rose 3.9% after the transport tanker and vessel owner said it has acquired 11 newbuild LNG carriers from Capital Maritime for $3.1 billion.
