Key Highlights
- Samsung Electronics shares climbed 10.1% to close at an all-time high on Monday, June 1, 2026.
- Nvidia’s CEO Jensen Huang is scheduled to travel to South Korea this week for meetings with Samsung, LG, and additional Korean technology leaders.
- The company started delivering sample units of its cutting-edge HBM4E (high-bandwidth memory) technology to clients, gaining an edge over competitors.
- Potential work stoppage involving approximately 48,000 unionized employees was prevented following a 74% approval vote on a revised compensation package.
- LG Electronics reached its daily trading cap of 29.9% for consecutive days, while Naver climbed 16% amid anticipated meetings with Huang.
Samsung Electronics (005930) witnessed a historic trading session on Monday, posting a remarkable 10.1% gain as three pivotal developments materialized simultaneously. The anticipated South Korea visit by Nvidia CEO Jensen Huang this week, significant progress in advanced memory chip technology, and resolution of labor disputes combined to fuel one of the company’s most impressive daily performances in recent memory.

The rally elevated Samsung’s total market capitalization beyond the 2,000 trillion won threshold when including preferred stock — a significant benchmark that highlights the transformative impact of artificial intelligence investment trends on the Korean semiconductor giant’s valuation.
Huang’s arrival in Seoul is anticipated later this week. His itinerary includes a meeting with LG Group’s Chairman Koo Kwang-mo alongside other prominent Korean technology executives. Nvidia will additionally host a “Korean Partner Night” event during the COMPUTEX technology conference in Taipei, which will feature participation from both Samsung and SK Hynix leadership.
“Jensen’s visit to Korea has a major implication. Nvidia needs Korea,” said Jeff Kim, analyst at KB Securities.
This trip carries substantial weight. Last year, Nvidia made commitments to deliver more than 260,000 of its cutting-edge AI processors to South Korea’s government agencies and major corporations, including Samsung and Hyundai Motor Group.
HBM4E Breakthrough
On the technology front, Samsung announced it has initiated shipments of groundbreaking 12-layer HBM4E sample units to significant global partners. HBM4E represents the next evolution in high-bandwidth memory technology — specialized chips that integrate with sophisticated AI processors to deliver data at exceptional speeds.
This development carries particular significance because Samsung has lagged behind SK Hynix in the HBM market throughout most of the artificial intelligence revolution. The HBM4E shipment announcement provided investors with evidence that this competitive deficit may finally be narrowing.
“Samsung has been valued at a discount to SK Hynix due to its weaker competitiveness in HBM, but the news appears to be supporting share price gains,” said BNK Investment & Securities analyst Lee Min-hee.
Nvidia’s most sophisticated processors require dependable HBM supply chains. While a CEO visit to a memory manufacturer doesn’t guarantee a contract — it clearly signals where critical supply constraints exist.
Labor Conflict Resolved
Contributing to the positive momentum, Samsung eliminated a significant labor uncertainty that had been pressuring the stock. Approximately 48,000 union members voted to accept a revised compensation and benefits package, preventing a scheduled 18-day work stoppage. The agreement secured roughly 74% approval.
The settlement incorporates a performance-based bonus framework, allocating 10.5% of semiconductor division operating profits toward special payments for chip manufacturing employees.
For market participants, the primary concern centered less on labor-management relations and more on potential supply chain disruption. Samsung’s semiconductor manufacturing facilities play a crucial role in global memory chip supply, and any interruption would have arrived at a particularly inopportune moment.
A judicial decision had already minimized the possibility of complete production shutdown by mandating essential staffing levels at certain facilities during any strike action. The official ratification eliminated the final remaining uncertainty.
The optimistic sentiment rippled through South Korea’s technology sector. LG Electronics reached its maximum daily trading limit of 29.9% for the second consecutive session, also achieving a record high. Naver advanced 16% following confirmation that senior executives would meet with Huang on Friday.
South Korea’s semiconductor exports climbed to an unprecedented level in May, contributing to the nation’s overall export growth posting its largest increase in more than four decades.
