Analysis
The recent 40% surge in the iShares MSCI South Korea ETF (EWY) marks a definitive turning point for the global semiconductor industry, signaling that the AI recovery has moved from speculative software valuations into the hard infrastructure of memory and logic. This rally is particularly significant as it is being fueled by an unexpected demographic: retirees. Traditionally risk-averse, this group is increasingly viewing South Korean chipmakers not as volatile cyclical plays, but as essential utilities for the global AI ecosystem. This shift in retail sentiment suggests a broader market confidence that the AI supercycle is a fundamental shift in global industrial capacity rather than a localized tech bubble.
At the heart of this resurgence are Samsung Electronics and SK Hynix, the twin pillars of the South Korean economy. For much of the previous cycle, these firms faced headwinds from a sluggish smartphone market and excess inventory. However, the explosion in generative AI has created an insatiable demand for High Bandwidth Memory (HBM), a specialized type of DRAM that sits adjacent to AI processors like those produced by Nvidia. SK Hynix, in particular, has emerged as a primary beneficiary, leveraging its early-mover advantage in HBM3E to secure a dominant position in Nvidia’s supply chain. The company’s recent unveiling of the world’s first 1c-based LPDDR6 chip further cements its role as a technical vanguard in the AI era.
The company’s disclosure of a staggering $25.6 billion investment in research and development for 2025 underscores its all-in strategy.
Samsung Electronics, while initially slower to pivot its HBM production, has responded with overwhelming force. The company’s disclosure of a staggering $25.6 billion investment in research and development for 2025 underscores its all-in strategy. This capital expenditure is focused on narrowing the gap with SK Hynix in HBM4 development and expanding its foundry business to compete with TSMC. For investors, this massive R&D commitment serves as a signal of long-term durability, suggesting that the current recovery is backed by fundamental technological advancement rather than mere market sentiment. The scale of this investment is nearly unprecedented in the memory sector, reflecting the high stakes of the AI hardware race.
What to Watch
Beyond the technical specifications, a significant driver of the EWY surge is a shift in South Korean corporate governance. The Value-Up program, initiated by the South Korean government to address the perennial Korea Discount, has finally begun to show results. The recent decision by Samsung and SK to cancel a combined $14 billion in treasury shares is a landmark move for shareholder returns. By reducing share counts and improving transparency, these companies are making themselves more attractive to retail investors and retirees who prioritize capital efficiency and dividend potential. This structural reform is providing a floor for valuations that were previously suppressed by complex corporate hierarchies.
However, the path forward is not without risks. Recent geopolitical tensions briefly wiped out nearly $200 billion in combined market value from the sector, highlighting the fragility of global semiconductor supply chains. Furthermore, as Broadcom and other ASIC designers ramp up their own AI chip efforts, the competition for memory capacity will only intensify. Analysts suggest that the HBM4 race will be the next critical battleground, with SK Hynix’s leadership already coordinating closely with Nvidia to define the next generation of AI hardware standards. For the AI and machine learning sector, the message is clear: the bottleneck is no longer just compute power, but the memory bandwidth required to feed that compute. As retirees and institutional investors alike pile into South Korean equities, they are betting that the world’s appetite for data will continue to outpace the industry’s ability to store and move it.
