At 10:30, gave a shout in the TG group, then the Korean government stepped in to stabilize, SK Hynix rebounded, and A-share Zhongji Innolight started to recover and bounce back. Sure enough, everything turned green in the afternoon, happily pocketed 5% (probably going to ride this wave for a bit). PCB -> Semiconductors (a few other sectors will gradually take their turn, focusing on the main rebound first). Later, we can shift to sub-sectors to catch another bounce.
