The U.S. stock market in New York opened trading on the 9th (after 11:30 p.m. Korean time) with all three major indexes rising simultaneously. This marks a rebound after overcoming the shock of the sharp selling that hit AI-related technology stocks last week. However, uncertainty surrounding Nvidia and caution ahead of the U.S. inflation data release still linger.

After 11:30 p.m. Korean time on the 9th, the Dow Jones Industrial Average on the New York Stock Exchange (NYSE) stood at 51,873.64, up 587.91 points (1.15%) from the previous trading day. The S&P 500 index rose 77.03 points (1.04%) to 7,453.89, while the tech-heavy Nasdaq Composite climbed 303.57 points (1.24%) to 24,882.99.

The Nasdaq started from the previous day's close of 24,579.42 and moved above the 24,800 level, briefly surpassing the 24,900 mark during the session with an intraday high of 24,906.62. The S&P 500 rose as high as 7,458.42 intraday, and the Dow reached 51,951.86. The small- and mid-cap-focused Russell 2000 also gained 171.81 points (1.83%) to 9,562.06, showing the upward momentum spreading across the broader market.

■ Rebound After AI Selloff Shock... Regulatory Concerns Were the Starting Point

This rally draws attention as it comes after the AI-related stock selloff that battered U.S. markets last week. U.S. stocks underwent a sharp correction amid overlapping concerns over potential regulation of the AI industry and doubts about the profitability of massive data center investments.

In particular, after the Democratic Party's victory in the U.S. midterm elections, the possibility of regulation on the AI industry and data center expansion emerged as a new market variable. Reuters reported on the 6th that the Democrats' election victory fueled concerns about tighter regulation of the AI industry in connection with the recent sharp volatility in U.S. markets. Massive expansion of AI data centers raising issues such as power demand, burdens on local communities, and rising investment costs has weighed on technology stock investor sentiment.

Amid these concerns, the Nasdaq plunged 5.52% and the S&P 500 fell 4.36% in U.S. markets on the 5th. In the following session on the 6th, the Nasdaq rebounded 1.09% and the S&P 500 rose 0.31%, but the Dow fell 0.46%, preventing a market-wide recovery. However, with all three major indexes rising simultaneously in early trading on the 9th, the possibility of a recovery in investor sentiment is once again being highlighted. In the market, buying is flowing into stocks that posted the largest declines, with moves also underway to assess whether the recent plunge was excessive.

■ Nvidia Uncertainty... Independent Probe Launched Over CEO Jensen Huang

Still, it remains difficult to judge whether this rebound will lead to a full-fledged uptrend. New uncertainty surrounding Nvidia has emerged as a variable in the technology stock market.

According to Reuters, Nvidia's board has launched an independent investigation following recent reports that CEO Jensen Huang became a target of a foreign intelligence agency's intelligence-gathering activities. The board plans to review the matter with support from outside legal experts, and stated that there is currently no basis to conclude that national security or the company's confidential information has been compromised.

However, upon the news, Nvidia's shares fell about 5% in pre-market trading on the 9th. Investors are closely watching, as increased volatility in the shares of Nvidia, a bellwether of the AI industry, could also affect semiconductor and data center-related stocks.

■ Interest Rate and Inflation Variables... CPI Release on the 10th in Focus

The outlook for U.S. monetary policy is also a key variable. U.S. nonfarm payrolls rose by 165,000 in October, beating market expectations, while the unemployment rate came in at 4.1%. A stronger-than-expected labor market could be interpreted as a signal that the U.S. economy's underlying strength remains intact, but it could also act as a factor weakening expectations for Federal Reserve rate cuts. The market is even discussing the possibility of a benchmark rate hike in December.

The U.S. October Consumer Price Index (CPI), due out on the 10th, is also cited as a major variable that will determine the stock market's direction. If inflationary pressure comes in higher than expected, Treasury yields could rise and weigh further on technology stocks. Conversely, if a trend of price stability is confirmed, investor sentiment toward recently battered growth stocks could improve.

■ What to Watch Going Forward

The simultaneous rally on Wall Street on the 9th shows that buying is flowing in after last week's plunge, but it is hard to say the burdens of regulatory uncertainty in the AI industry and the interest rate outlook have been fully resolved. With the Nasdaq briefly topping the 24,900 level in early trading, whether the upward momentum can be sustained at that level is a short-term point of focus. Whether the S&P 500 can settle above the 7,450 mark and the Dow's potential approach to the 52,000 level are also drawing attention.

Whether U.S. stocks continue their recovery from last week's plunge or volatility expands again ahead of the inflation release depends on supply and demand during the remaining trading hours and the movement of large-cap technology stocks. Current index levels are intraday figures and may differ from final closing results.
