Stock indexes in Japan and South Korea plunged over 2% on Thursday as investors took cues from Wall Street overnight.

Japan’s Nikkei 225 fell 2.13%. South Korea’s Kospi index slipped 2.20% to its lowest level since early January.

South Korea’s Kosdaq index tumbled over 3%. Shares of South Korean tech stocks were also pressured by a 3.63% fall in chipmaker SK Hynix after its announced quarterly results.

Investors also assessed data from South Korea that showed the economy grew at a slightly higher-than-expected pace in the third quarter.

Shares of South Korean chip supplier SK Hynix fell 3.92% after the firm announced a 2.18 trillion won ($1.61 billion) net loss for its third quarter, in contrast to a 1.11 trillion won net profit in the same period a year ago.

Revenue fell 17% year on year to come in at 9.07 trillion won. The company also recorded an operating loss of 1.79 trillion won compared to an operating profit of 1.66 trillion won in the third quarter of 2022.

However, SK Hynix highlighted that on a quarter on quarter basis, its losses narrowed as its net loss and operating loss shrank 27% and 38% respectively compared to the second quarter.

“With the effect of the production reduction by global memory providers starting to be seen and customers, following efforts to reduce inventories, placing new orders now, semiconductor prices are starting to stabilize,” the company said.

South Korea’s economy grew at a slightly faster-than-expected pace in the third quarter, according to data from the Bank of Korea.

Gross domestic product grew 0.6% in the July-September quarter from the prior quarter. A Reuters survey had forecast a median 0.5% increase for the third quarter.

Focus will now move to the Bank of Korea’s next policy meeting in late November, where it is to be seen how economic data points like these will impact the central bank’s monetary policy decision.

Investor sentiment around artificial intelligence has soured on the back of the U.S. government’s recent export curbs on AI chips — but Goldman Sachs is still bullish.

“While investor sentiment around AI is weaker of late especially following new U.S. regulations, we think global competition could make the introduction of AI to major industries a primary focus,” the investment bank’s analysts wrote in an Oct. 23 note to investors.

CNBC Pro takes a look at some of the stocks in Goldman’s conviction list. They belong to two categories: those that enable AI and those empowered by AI.

U.S. chipmaker Nvidia has been getting a lot of love from market watchers this year – and growth investor Nick Griffin is no exception.

The founding partner and chief investment officer at the Australia-headquartered Munro Partners says he has “always liked” Nvidia, even while it might be considered “a very difficult stock to own.”

Nvidia “is in about 700 ETFs [exchange-traded funds] and it goes all over the shop. I think I said at the start of 2022 that I thought Nvidia would be the biggest company in the world – and it fell 60% that year and has since risen another 300% since then,” Griffin said during CNBC’s Pro Talks.

Year-to-date, shares in the chipmaker are up nearly 200%, even as it experienced a pullback in the past week following the U.S. government’s curbs on the export of artificial intelligence chips to China over concerns they could be used for military development purposes. This will restrict the export of chipmaker Nvidia’s A800 and H800 chips, according to the officials.

Pershing Square’s Bill Ackman pocketed about $200 million from his latest Treasury trade, the Financial Times reported Wednesday, citing people familiar with the bet.

The hedge fund manager revealed Monday he covered his bet against 30-year Treasurys, believing that investors may increasingly buy bonds as a safe haven because of growing geopolitical risks.

“There is too much risk in the world to remain short bonds at current long-term rates,” Ackman said in a post on X, formerly known as Twitter, on Monday morning. “We covered our bond short.”

The firm’s flagship fund has rallied 11.6% this year through Oct. 17.
