Global semiconductor stocks experienced a sharp sell-off on Tuesday, with industry giants like SK Hynix and Samsung Electronics seeing significant share price drops. This downturn reflects ongoing volatility in the chipmaking sector, influenced by Wall Street performance and growing uncertainties surrounding the AI investment cycle.
Experts suggest that while the long-term outlook for AI remains strong, current market fluctuations are exacerbated by limited visibility into AI’s economic impact and the potential influence of leveraged trading products. Analysts also point to China’s growing ambitions in chip manufacturing as a factor contributing to investor caution.
SK Hynix Plunges 13% as Global Chip Sell-Off Intensifies
By A Wall Street News Editor
South Korean semiconductor stocks experienced a significant downturn on Tuesday, mirroring a broader rout in the chipmaking sector that extended from Wall Street. SK Hynix saw its shares plummet over 13%, while Samsung Electronics also suffered substantial losses. This sharp decline highlights the increasing volatility and sensitivity of the semiconductor market to global economic shifts and investor sentiment.
The semiconductor industry faced a brutal trading session on Tuesday, with major players across Asia and Europe experiencing significant share price drops. The sell-off echoed a weak performance on Wall Street, signaling a deepening concern among investors about the future of chip demand and valuations.
SK Hynix, a key player in the AI chip market, saw its shares tumble by 14.65% by the close of trading. Rival Samsung Electronics was not spared, falling over 13%. The downturn extended to other AI-linked companies, with Samsung SDI dropping 11.37%, LG Innotek falling 16.29%, Seoul Semiconductor down 8.78%, and LG Chem losing 7.5%.
The turmoil was not confined to South Korea. In Japan, semiconductor stocks also declined sharply. Tokyo Electron closed down 10.96%, while Advantest slid over 10%. SoftBank Group, a significant investor in AI through its stake in Arm, fell 4.43%. Japan's memory chip manufacturer, Kioxia, bore the brunt of the selling, plunging more than 18%.
Taiwan's TSMC finished the day nearly 3% lower. Mainland China's tech-heavy ChiNext 300 index was down 6.49%, and the Hang Seng China Semiconductor Chips Index fell 7.02%.
The weakness permeated into European markets, where key chip companies saw considerable losses in early trade. ASML shares were slightly lower, following reports that a Chinese company is reportedly mass-producing its own immersion deep ultraviolet lithography machines, challenging ASML's dominance in this critical area. ASML had already experienced an 8% drop on Monday.
Other European semiconductor firms, including ASM International and BE Semiconductor, also saw their share prices fall between 2% and 3% in early trading.
This broad market decline in semiconductors follows another challenging session for U.S. chip stocks on Monday. The VanEck Semiconductor ETF (SMH) lost over 2%, adding to its recent losses. Companies like AMD, Teradyne, and Micron Technology all experienced significant drops, shedding 5%, 4%, and 2% respectively.
The interconnectedness of Asian technology shares and the U.S. AI trade was evident in this widespread sell-off. Companies like Samsung Electronics and SK Hynix are critical suppliers of high-bandwidth memory chips essential for AI servers, making their stock performance highly sensitive to the spending plans of major U.S. tech giants.
Owen Lamont, senior vice president at Acadian Asset Management, commented on the situation, highlighting the significant uncertainty surrounding the AI investment cycle. He noted that investors have limited visibility into AI's long-term economic impact, leading to potential market volatility. Lamont also suggested that leveraged exchange-traded products could be exacerbating these market swings.
Sundeep Gantori, chief investment officer for equities at Standard Chartered, pointed to a broader deterioration in sentiment toward semiconductor stocks, partly driven by reports of China's advancements in memory chips and lithography equipment. Despite the current turbulence, Gantori maintains a positive long-term outlook, emphasizing the substantial market opportunity for multiple industry players and the continued support from the AI investment cycle for leading technology firms. He also noted that recent broker reports suggesting a memory price peak in 2027 align with Standard Chartered's view, and that current valuations present an improved risk-reward profile.
