On One Side: Unstoppable AI Giant

SK Hynix is a key player behind artificial intelligence. They produce HBM, a specialized memory that serves as the "brain" of AI chips like those made by Nvidia.

· Market Dominance: They control about 60-70% of the HBM4 supply for the Nvidia Vera Rubin platform and have established long-term development partnerships with Nvidia.
· Financial Performance: Operating profit for the second quarter of 2026 is estimated to reach a record 60-70 trillion Won, far surpassing previous records.
· Super Cycle: Bank of America calls this a "super cycle" reminiscent of the semiconductor boom of the 1990s.

🌪️ On the Other Side: A Storm Strikes

However, this greatness makes its stock highly sensitive to market sentiment. On June 26, 2026, SK Hynix stock plunged more than 10% in a single day on the Korean market.

What Caused It?

1. Technical Correction Report: SK Hynix stock had actually risen more than 300% throughout 2026. This increase caused technical indicators, such as the RSI, to enter overbought territory, making it prone to a correction.
2. Apple's Domino Effect: Apple raised prices on Macs and iPads due to high memory costs. Investors interpreted this as a signal that chip cost pressure had reached a limit that even Apple could not bear, triggering massive sell-offs in memory producers like SK Hynix.

Reflection

SK Hynix shows two faces: extraordinary fundamental strength and extremely fragile market sentiment. This reminds us of the teachings of Mbah Joyo: "Prices go up and down, but value never disappears." Can we see the value behind the panic?
