About ten minutes after the stock exchange opened, the broad S&P 500 index and the technology-heavy Nasdaq composite index have fallen by 0.3 and 0.2 percent, respectively, and the Dow Jones industrial index by 0.6 percent.
Processor manufacturer Intel is still struggling with a decline of 0.6 percent.
This is after Wednesday's fall of 7 percent.
Also, five of the very index-heavy so-called "magnificent seven" companies – e-commerce giant Amazon, iPhone manufacturer Apple, Facebook's parent company Meta, software company Microsoft, semiconductor company Nvidia, and electric car company Tesla – have started Thursday in negative territory.
The other two, Google owner Alphabet and semiconductor company Nvidia, have risen.
After the stock exchange closed on Wednesday, all seven were in the red.
Also, retail giant Walmart, minus 5.2 percent, is weighing down Thursday's development.
