Why is the After-Hours Block Trade Important?

Should I Invest in SK Hynix Now?
SK Hynix is a key beneficiary of the AI market and leads the HBM market. Strong performance, solid financials, active technology investment, and shareholder return policies enhance its long-term investment value. However, macroeconomic uncertainty, raw material price fluctuations, and intensified competition are risk factors. Overall Opinion: BUY
