Nvidia's sell-off on Wall Street causes Asian chip stocks to decline.

• In Asia, chip and tech stocks began the day with a sharp decline on Wednesday, mirroring the steep drop in Nvidia's US share price the previous night.

The decline in Nvidia's share price in the U.S. led to a drop in Asia's semiconductor and associated stocks on Wednesday morning.

In the U.S., a chipmaker plummeted more than 9% in regular trading, causing semiconductor stocks to decline. This happened amid a sell-off on Wall Street, which was triggered by economic data published on Tuesday. Nvidia shares continued to slide in post-market trading on Tuesday, falling 2%, after Bloomberg reported that the company received a subpoena from the Department of Justice as part of an antitrust investigation.

SK Hynix and Samsung Electronics are part of Nvidia's value chain in South Korea.

The decline in Samsung shares by 2.6% and SK Hynix by more than 6% led to a 2.5% drop in the Kospi index, while the Kosdaq index fell by 3%. SK Hynix produces high bandwidth memory chips that are used in Nvidia's AI chipsets.

While other direct suppliers to Nvidia dropped 7%, semiconductor testing equipment suppliers shed more than 8%.

A Japanese investment holding company that holds a stake in a chip designer experienced a 6% decline.

Nvidia has a strategic partnership with Taiwan's Foxconn, which recently lost 5%.

On Tuesday stateside, Nvidia wiped out $279 billion in market cap.
