AI-generated summary

As the Democratic Party reportedly took control of all federal congressional powers, including the House of Representatives and the Senate, concerns about regulation of AI data centers arose, leading to concerns about demand for semiconductors. However, the sharp decline calmed down as analysis emerged that AI regulations would only amount to the imposition of some power-related environmental taxes.

In particular, as AMD achieved record-high performance in the third quarter due to a surge in demand for AI data center chips and presented performance guidance that exceeded market expectations in the fourth quarter, its stock price rose significantly not only in regular trading but also in after-hours trading, acting as a positive factor for the domestic stock market.
However, as the U.S. midterm election counting began and Nasdaq 100 index futures fell, KOSPI also lost its upward momentum and began to plummet.
As the Democratic Party is said to be taking control of all federal congressional powers, including the House of Representatives and the Senate, concerns about semiconductor demand have arisen due to regulations on AI data centers.
However, as analysis emerged that AI regulations would only amount to the imposition of environmental taxes related to some electricity, the sharp decline calmed down and the KOSPI also rebounded.
Kim Dae-jun, a researcher at Korea Investment & Securities, said, “From the Democratic Party’s perspective, it is essential to secure an edge in the competition for technological hegemony with China,” and added, “Excessive regulation of the AI industry is realistically difficult.”

KOSPI, which started strong thanks to the rebound in U.S. semiconductor stocks, plunged more than 4% during the day, but then made up for the loss, showing a roller KOSPI market. Samsung Electronics and SK Hynix stock prices also fluctuated significantly. Analysis suggests that the Democratic Party's possibility of a landslide victory in the U.S. midterm elections and concerns about strengthening data center regulations have increased uncertainty in the semiconductor industry.

With net selling by foreign investors continuing for seven consecutive months, securities companies pointed out the shift to foreign net buying as a key to the KOSPI's rebound. However, due to external uncertainties such as high interest rates, semiconductor peak-out, and the U.S. midterm elections, it is predicted that the return of foreign net purchases will likely take at least three months.
