• Plug Power (NASDAQ:PLUG) (PLUG) stock fell 14% after the alternative-energy company said it had begun a $200 million stock offering, the latest chapter in its liquidity issues.

• Arm Holdings (NASDAQ:ARM) stock rose 3.7% after analysts upgraded its stance on the semiconductor to ‘overweight’ from ‘equal-weight’, while lifting its price target to $190 from $107, saying Arm products will be “fundamental to the successful emergence of edge AI.”
