Since the start of this year, SK Hynix's stock price has witnessed an extraordinary surge of nearly 240%. This remarkable rise has led the Korean Exchange to take the unusual step of issuing a cautionary note to investors, subtly suggesting that the stock might be experiencing an overheating phase. On Monday evening, the exchange formally issued an "investment caution notice," highlighting the substantial spike in SK Hynix's stock price. It's worth noting that this notice remains effective for just one day. On Tuesday, SK Hynix's shares experienced a significant drop of up to 5.3% on the Korean Stock Exchange, marking the steepest decline in three weeks. Such a move by the exchange is quite rare when it comes to large-cap stocks. For context, similar warnings were also issued last month for Doosan Co. and Hanwha Ocean Co.
