The September Effect and Historical Data

It is stated that historically, the average return rate in Septembers has stood at approximately minus 1.17 percent.

Psychological and Economic Reasons for the Decline

Behind the September slump in the markets lie psychological factors stemming from investors' expectations of weak performance from past periods.

As the year-end approaches, profit-taking, tax-loss harvesting strategies, and the Federal Reserve's economic decisions also play a role in the declines.

Status of Artificial Intelligence Stocks

While artificial intelligence stocks may also be affected by potential broad market pullbacks, companies like Nvidia and Micron Technology maintain their strong portfolio positions.

Nvidia's fiscal 2027 second-quarter revenue more than doubled year-over-year to reach $96.2 billion, and its earnings per share came in at $2.22.
