Overnight, the three major U.S. New York stock indexes ended mixed. On the 26th (local time) at the New York Stock Exchange (NYSE), the Dow Jones Industrial Average finished at 49,499.20, up 17.05 points, or 0.03%, from the previous session.
In contrast, the Standard & Poor's (S&P) 500 fell 37.27 points, or 0.54%, to 6,908.86, and the Nasdaq composite lost 273.69 points, or 1.18%, to 22,878.38 at the close.
The previous day, Nvidia, the No. 1 company by market capitalization, announced it posted record-high revenue. Nvidia disclosed that revenue for the fourth quarter of the fiscal year (November last year to January this year) was $68.13 billion (about 98 trillion won), up 73% from a year earlier. But when the market opened, investors began selling Nvidia. It is interpreted as selling on the "news." Nvidia fell 5.46%.
Min Kyung-won, a Woori Bank researcher, said, "Overnight, the New York stock market plunged despite Nvidia's strong results," and added, "Deteriorating investor sentiment toward growth stocks led to a rise in the dollar index (which reflects the value of the U.S. dollar against major currencies)."
