China Stocks Slump on Semiconductor Selloff

2026-08-19 02:08 By Czyrill Jean Coloma 1 min. read

The Shanghai Composite tumbled 2.40% to close at 3,894.4 on Wednesday, while the Shenzhen Component slumped 5.01% to 13,890.2, as a broad selloff in semiconductor stocks weighed heavily on both benchmarks.

Chipmakers came under pressure worldwide as government bond yields surged amid persistent inflation, elevated fiscal spending, and heavy debt issuance.

In addition, geopolitical tensions fueled concerns over energy supply disruptions, reinforcing fears that inflation and financing costs could remain elevated.

The decline followed GigaDevice's H1 2026 results, which slightly missed the company's expectations despite revenue soaring 178.7% year-on-year to RMB 11.57 billion and net profit surging 1,091.5% to RMB 6.86 billion.

SMIC (-5.16%), Cambricon Technologies (-9.64%), Hygon Information Technology (-7.26%), GigaDevice (-7.56%), Hua Hong Semiconductor (-11.92%), Zhongji Innolight (-9.36%), Eoptolink Technology (-9.0%), and NAURA Technology (-8.24%) were among the biggest decliners.

The Shanghai Composite fell 0.88% to close at a near three-month low of 3,767.2 on Wednesday, while the Shenzhen Component slumped 1.97% to a more than one-year low of 12,110.6, as investors weighed mounting cost pressures against resilient external demand. Producer price inflation climbed to 5.0% from 3.8%, its strongest increase since June 2022, as renewed Middle East hostilities and risks to global oil supplies drove up input costs and squeezed corporate margins.

On the trade front, China’s trade surplus widened to $133.53 billion in September from $88.72 billion a year earlier, its largest since January 2025.
