Micron and Alibaba fuel AI rally, Powell cautious, lithium deal

US stocks rebound after Tuesday’s dip, with Micron (MU) and Alibaba (BABA) driving AI optimism.

Alibaba surged to a four-year high after pledging to boost AI spending above $50B and launching a new language model while partnering with Nvidia (NVDA).
