The upstream PCB market is way hotter than I expected. Besides holding onto Shengyi Technology, I sold off copper foil and electronic cloth way too early—missed out on almost 50 points. Started positioning in PCB back in April, knew materials were going up, but didn’t expect upstream materials to surge like this. ‍ When I built my position, Shengyi Technology was over 50 yuan, and Nomura previously set a target of 96 yuan for Shengyi Technology. If Jukan hadn’t posted multiple times about the CCL shortage and price hikes, I might’ve sold at 100 too.
