Investment Bank Ups Outlook for Korean Tech Giants as Demand for Semiconductors Surges

Table of Contents Shares of SK Hynix rocketed 12.5% higher Monday, reaching an all-time peak as international capital flooded into South Korean semiconductor manufacturers. Samsung Electronics also advanced, posting a 5.4% gain, though significantly lagging behind its competitor. Samsung SDI Co., Ltd., 0L2T.L The rally followed robust quarterly results from multiple prominent U.S. technology corporations last week, which reinforced their commitment to capital expenditures focused on artificial intelligence infrastructure. SK Hynix serves as a critical provider of high-bandwidth memory chips, the sophisticated components essential for AI processing accelerators. Positive messaging from American tech giants regarding AI data center requirements typically triggers rapid movements in memory semiconductor equities. SK Hynix has emerged as one of the most obvious winners from this pattern. Barclays released an optimistic research report coinciding with Monday’s market action, increasing its valuation target for SK Hynix’s Frankfurt-traded shares by over 20%, moving from €900 to €1,100. The firm simultaneously raised its Samsung London-listed stock target from $4,000 to $4,250. Both companies maintained Overweight recommendations. The investment bank stated that the supply-demand disparity in the memory semiconductor sector “shows no signs of improving any time soon.” Barclays projects worldwide memory supply expansion in the low twenties percentage range for both 2026 and 2027, while anticipating demand growth to outpace supply, indicating the shortage will persist through both years. Barclays anticipates SK Hynix will maintain its dominant position in high-bandwidth memory production. The bank elevated its earnings valuation multiple for the stock to 6x 2026 projections, up from 5x, bringing it closer to how its U.S. research team evaluates Micron. Samsung’s relative weakness stemmed from workforce-related concerns. The company’s labor union staged a significant demonstration on April 23, pressing for increased profit-sharing from the semiconductor business unit. Management’s proposal including bonuses and salary adjustments was turned down. The union has now issued an ultimatum for an 18-day work stoppage beginning May 21 unless an agreement is achieved. This threat is dampening investor confidence during a period when AI memory chip demand remains robust. Samsung stated it intends to pursue ongoing negotiations with the union and has prepared contingency plans to handle any manufacturing interruptions. However, market analysts remain skeptical about the company’s ability to avoid disruption. Citigroup has already reduced its Samsung projections, highlighting probable expenses from labor concessions or enhanced compensation programs. Additional workforce-related costs could compress profit margins in a business segment that has been generating substantial earnings from AI-driven demand. Barclays increased its Samsung revenue projections by approximately 8% for 2026 and 17% for 2027, reflecting stronger-than-anticipated semiconductor pricing dynamics. The firm forecasted Samsung’s high-bandwidth memory revenue will triple in 2026. SK Hynix resolved its own employee profit-sharing negotiations earlier, providing the company with a workforce stability benefit now visible in its market valuation. Additional Asian semiconductor companies also gained Monday. MediaTek and ASE Technology Holding both experienced favorable price movements as investor sentiment toward AI chips strengthened. Barclays identified China as a potential concern, observing that Chinese memory manufacturers are increasing production capacity and making progress in mid-to-low tier smartphone markets, though the bank doesn’t expect this to impact the data center segment. Citigroup’s Samsung expectation reduction and heightened analyst focus on SK Hynix as a comparative outperformer represented some of the most recent developments entering the trading week.
