SK Hynix's stock price surged 20.6% this week, driven by two major positive developments: Singapore's sovereign wealth fund Temasek announced on Wednesday its investment in the company and Samsung, and Counterpoint Research's latest NAND memory market report indicated that SK Hynix benefited from competitors' supply constraints, with its subsidiary Solidigm also achieving strong growth. Furthermore, the overall bullish sentiment in the South Korean stock market also boosted the share price.
