The U.S. stock market experienced a downturn, influenced largely by a decline in the shares of tech powerhouse Nvidia, which contributed to a pullback from record highs.

On Monday, the S&P 500 index decreased by 0.6%, marking the end of its streak from what was the 57th record high this year. Simultaneously, the Dow Jones Industrial Average saw a reduction of 0.5%, while the Nasdaq composite mirrored the trend with a 0.6% dip, leaving both indexes below their respective peaks.

Nvidia emerged as a significant drag on the market following reports that Chinese authorities are investigating the company for possible antitrust issues. Interestingly, stocks in Hong Kong surged as Chinese leadership committed to a policy that favors a “moderately loose” monetary stance. Additionally, the prices of oil and gold increased in response to the recent political shifts in Syria, particularly the removal of President Bashar Assad.

The specifics for the day were as follows:
The S&P 500 dropped 37.42 points, or 0.6%, closing at 6,052.85.

The Dow Jones Industrial Average declined by 240.59 points, equivalent to 0.5%, ending at 44,401.93.

The Nasdaq composite fell 123.08 points, or 0.6%, finishing the day at 19,736.69.

The Russell 2000 index, representing smaller firms, decreased by 16.16 points, roughly 0.7%, to settle at 2,392.84.

Looking at year-to-date performance, the S&P 500 has gained 1,283.02 points or 26.9%, while the Dow has risen by 6,712.39 points, equating to 17.8%. The Nasdaq has advanced by 4,725.34 points, reflecting a growth of 31.5%, and the Russell 2000 is up by 365.76 points, or 18%.
