Shares of SK Hynix surged by as much as 11% on Wednesday, pushing the market capitalization of the South Korean semiconductor giant beyond $1 trillion. This increase is part of a broader trend, as investors flock toward companies linked to artificial intelligence, particularly in the semiconductor sector.
The remarkable rise of SK Hynix shares — which have skyrocketed approximately 250% since the beginning of the year — is attributed largely to rising demand for high-bandwidth memory chips, essential components used in artificial intelligence servers and accelerators. SK Hynix has positioned itself as a crucial supplier to AI chip leader Nvidia, thereby solidifying its role at the nexus of the global AI supply chain.
This recent rally comes soon after Samsung Electronics, a domestic competitor, also surpassed the $1 trillion market capitalization milestone. On the same day, Samsung’s shares grew by more than 6%. Collectively, these two semiconductor powerhouses now represent over 40% of South Korea’s benchmark Kospi index, illustrating an important correlation between the index’s performance and global demand for AI-related semiconductors and memory chips. Data from LSEG reveals that the Kospi index has nearly doubled since the year’s onset.
However, analysts have cautioned that such concentration within the index could increase market volatility and expose it to potential risks, including supply chain disruptions and a decline in global data center investments. Despite these concerns, analysts believe SK Hynix’s stock may have further upward potential. Peter Kim, a global investment strategist at KB Financial Group, noted that earnings upgrades are currently outpacing share price increases, suggesting that the fundamentals and valuations for SK Hynix and Samsung Electronics remain solid.
Kim remarked that, in fact, SK Hynix is becoming “cheaper” as earnings forecasts are revised upwards more rapidly than its share price has risen. This observation points to a potentially favorable outlook for the company in the fast-evolving semiconductor market.
