On February 9th, SK Hynix's stock price surged 6.3%, closing at 892,000 won, benefiting from the progress of HBM4 mass production and the soaring NAND prices. The market reacted positively to its plans to build a new advanced packaging plant at its Cheongju factory. Samsung Electronics' GDR fell slightly by 0.423% that day, closing at $2,828.00, a normal adjustment due to short-term market volatility. It remains strongly supported by the memory supercycle in the long term, and its stock price on the Seoul Stock Exchange rose in tandem, with a cumulative increase of over 30% this year.
