description: "Several semiconductor/optical companies had a rough night, with Tianyue Advanced and Innoscience continuing to fall. It seems the semiconductor sector hasn't fully heated up yet, but the faithful fans are holding strong. On the other hand, Sunny Optical's profit alert + buyback this round is truly enviable—the FOMO feels so real. I'm basically just passively watching Cambridge Technology's paper gains now, hoping the AI sector can show some strength. As for Foxconn Interconnect Technology's insider selling—utterly ridiculous. Working folks are exhausted."
