People walk past the logo of Samsung Electronics in Seoul on July 7, 2022. South Korea’s Samsung Electronics Co Ltd turned in its best April-June profit since 2018 on Thursday, underpinned by strong sales of memory chips to server customers even as demand from inflation-hit smartphone makers cools.

Global semiconductor and associated stocks fell on Wednesday, following a steep plunge in Nvidia’s share price in the U.S. overnight.
In the U.S., chipmaker Nvidia plunged more than 9% in regular trading, leading semiconductor stocks lower amid a sell-off on Wall Street. Economic data published Tuesday resurfaced jitters about the health of the U.S. economy. Nvidia shares continued sliding in post-market trading Tuesday, falling 2%, after Bloomberg reported that the company received a subpoena from the Department of Justice as part of an antitrust investigation.
Around $279 billion of value was wiped off of Nvidia on Tuesday, in the biggest one-day market capitalization drop for a U.S. stock in history. The previous record was held by Facebook-parent Meta, which suffered a $232 billion fall in value in a day in February 2022.
Nvidia’s value chain extends to South Korea, namely, memory chip maker SK Hynix and conglomerate Samsung Electronics.
Samsung shares closed 3.45% lower, while SK Hynix, which provides high bandwidth memory chips to Nvidia, slid 8%.
Tokyo Electron dropped 8.5%, while semiconductor testing equipment supplier Advantest shed nearly 8%.
Japanese investment holding company SoftBank Group, which owns a stake in chip designer Arm, fell 7.7%.
Contract chip manufacturer Taiwan Semiconductor Manufacturing Company declined more than 5%. TSMC manufactures Nvidia’s high-performance graphics processing units which power large language models — machine learning programs that can recognize and generate text.
Taiwan’s Hon Hai Precision Industry — known internationally as Foxconn — lost nearly 3%. It has a strategic partnership with Nvidia.
The selling in Asia filtered through to European semiconductor stocks. Shares of ASML, which makes critical equipment to manufacture advanced chips, fell 5% in early trade. Other European names such as ASMI, Be Semiconductor and Infineon, were all lower.
