SK hynix shares fell on September 11 and 12. The stock recorded a 2.2% decline. Investors reacted to reports that DeepSeek developed AI technology requiring less high-bandwidth memory (HBM).
Market analysts describe the sell-off as a potential overreaction. DeepSeek claims model-level efficiency, but global HBM demand remains driven by overall AI service throughput. Long-term consumption depends on broader AI system memory requirements.
The decline occurred during a period of broader volatility for memory stocks. Analysts maintain a positive outlook for SK hynix due to its dominant HBM market position. Rising demand for AI infrastructure continues to support the company's long-term prospects.
