Other chip companies also fell Friday, including a 4.1 per cent drop for Nvidia. After soaring earlier this year as its revenue surged on the AI frenzy, Nvidia's stock has been shaky since mid-July as investors question whether they took it too high. Because of its massive size, Nvidia's stock is one of the most influential on Wall Street, and it fell 13.9 per cent over the week. That's even though Nvidia has continued to top analysts' expectations for growth. On the winning side of Wall Street was US Steel, which rose 4.3 per cent after the CEO of rival Cleveland Cliffs told MSNBC that his company would still be interested in acquiring US Steel if the White House were to block its proposed sale to Japan's Nippon Steel.
