The S&P 500 (SPX) dipped on Wednesday as investors learned about the effects of a chip export ban to China. This ban doesn’t allow for advanced AI chips from U.S. companies to be sold to companies and other entities in China.
Nvidia (NVDA) revealed the negative effects of this chip export ban today when it said it would suffer a $5.5 billion charge related to it. This upset investors and caused NVDA stock to drop 6.79% as of this writing.
The S&P 500 isn’t performing well on the chip export ban, with the index down 1.07% as of this writing. Investors will note that the SPX has dropped 10.01% over the last three months and has fallen 8.25% year-to-date.
