According to BlockBeats, on July 27, the South Korean presidential office, Cheong Wa Dae, announced on July 25 that, taking advantage of the San Francisco Artificial Intelligence Summit, South Korean companies and global technology giants reached semiconductor cooperation agreements totaling $950 billion.

Specifically, Samsung Electronics and Broadcom signed a memorandum of understanding to collaborate over the next five years on a $200 billion supply of high-end memory chips and AI chip wafer foundry production; SK Group will advance a five-year, $750 billion long-term supply partnership for high-end memory chips with major global technology companies such as Nvidia.

However, large orders are not enough to save the South Korean stock market. According to Bitget, SK Hynix opened higher this morning but has continued to fall, currently down more than 0.8%. As a result, the South Korean KOSPI index has fallen by 0.93%.

Analysis indicates that the frequent occurrence of "sell-on-news" reactions to positive news proves that the global market is no longer responding positively to AI-related benefits.
