Samsung and Hynix fell before the South Korean market opened.

In pre-market trading in South Korea's Nextrade on Friday, Samsung Electronics' stock price plummeted by nearly 8%, while SK Hynix's stock price fell by as much as 9.3%. This sharp decline indicates that market volatility during regular trading hours may increase, especially in the semiconductor sector and other stocks related to artificial intelligence. On Thursday, the U.S. stock market experienced a dramatic reversal, with benchmark indices falling to their lowest levels in over two months. Despite Nvidia's optimistic profit forecast and its previous boost to the stock market, ongoing concerns about valuations suppressed the surge, leading to a 3.2% drop in the stock price of this leading company in the field of artificial intelligence.
