China’s STAR 50 Jumps 4.5% at Midday as Semiconductor and Computing-Power Stocks Rally

The STAR 50's outsized move relative to the Shanghai Composite points to a concentrated, hardware-led bid rather than broad risk appetite, with optical modules and PCBs doing the heavy lifting. Breadth of nearly 4,200 advancing stocks alongside falling travel and auto names suggests rotation into domestic semiconductor and computing supply chains rather than a uniform rally. Whether that leadership holds once the midday momentum fades, and whether turnover sustains, is the open question.
