Samsung Electronics surged 7%, CEO made a bold statement: "Samsung is back," HBM4 wins back customer trust.

```

Boosted by positive statements from the company's top management regarding the renewed customer recognition for its HBM4 (fourth generation high bandwidth memory) business, Samsung Electronics' stock price surged 7.2% on Friday, setting a new historical closing high and pushing South Korea's KOSPI index up by 2.3%, breaking the 4300-point mark for the first time in history.

Jun Young Hyun, Samsung Electronics' usually low-profile co-CEO, revealed in a New Year's address to employees that the company's HBM4 products have demonstrated "differentiated competitiveness" and have earned customers' high praise that "Samsung is back."

This statement greatly boosted investor confidence, with the market expecting that Samsung is gradually narrowing its previous gap with SK Hynix in the crucial high bandwidth memory market and is likely to re-enter Nvidia's core supply chain in 2026 with the next-generation HBM products.

The stock surge is also attributed to the overall resonance of Asian tech stocks and the strong support from industry fundamentals.

On Friday, fueled by the AI investment frenzy sparked by Biren Technology’s listing performance and related developments from DeepSeek, the Hang Seng Tech Index once soared by 4.3%.

On the macro front, South Korea's semiconductor exports in December surged 43% year-on-year, also confirming the importance of Samsung and SK Hynix in the global AI hardware boom.
